SkyQ Controls — Sales Reference

Start Here

The 60-second version

What SkyQ is, in six lines

SkyQ is the Verasys replacement. Same job — light-commercial equipment controls, zoning and a building-level front end — new hardware, new software, new protocol.
Built with Prolon. Bosch partners with Prolon, who have been doing light-commercial controls for decades. Prolon stocks and drop-ships every component.
The NC2000 is the heart. Everything wires back to the network controller: up to 127 devices on one Modbus trunk.
On our own equipment it is nearly plug-and-play. Smart Equipment Controls (SEC/SSE/UCB) auto-recognize, the graphics build themselves, and you get full SEC menu access — no graphics to draw, no points to map.
On third-party equipment you are back to the normal grind. A BACnet bridge if the unit has a card, a thermostat-style controller plus sensors if it does not.
You only buy hardware. Desktop, mobile and cloud software are free, with no license or subscription.

Know this before you promise it SkyQ is not a BAS and does not integrate upward. There is no BACnet/IP, and it is not designed to sit under a supervisory system. If the job needs to report into a building automation front end, SkyQ is the wrong answer — find that out on the first call, not at submittal.

Which controller do I need?

The equipment is…	Zoning	What you quote	Notes
Our Smart Equipment (SEC / SSE / UCB)	Single zone	Wire straight to the COM card	Add an NS8000 wall sensor. No extra controller.
Our Smart Equipment (SEC / SSE / UCB)	Multi zone	ZONEQ	Plus VC2000 zone controllers and SkyQ wall sensors.
Third party with a BACnet MS/TP card	Either	BAC-EQB	Cheapest and fastest. Up to 32 exposed points.
Third party without a card	Single zone	M2000‑RTUS / ‑HPS	Wires like a thermostat. You add supply, return and outside-air sensors.
Third party without a card	Multi zone	M2000‑RTU / ‑HP	Same wiring, zoning logic on board.
Sun Premier	Either	BAC‑EQB	Premier is treated as third party for now — 32 points, same as anyone else’s unit. Full integration targeted for roughly mid‑2027.
Not a packaged unit at all	n/a	M2000‑FLX	Flexible I/O for exhaust fans, pumps, lighting, SCR reheat. Boiler and simple chiller applications exist too.

Rule of thumb If the third-party unit already has a BACnet card, use the BAC‑EQB — it is the cheaper device, it is one communication wire, and existing wall sensors can stay on the wall. Reach for the M2000 only when there is no card to talk to.

The Hardware

11 devices · every part number

Everything below hangs off the NC2000. Part numbers are the ones you will see in Sel Nav and on the data sheets at skyqcontrols.com.

NC2000 — Network Controller

The gateway, and the direct replacement for the Verasys Smart Building Hub (SBH300). Everything wires back to it. It carries the global functions — scheduling, trending, shared data — and it is what the desktop, mobile and cloud apps connect to. One NC2000 supports up to 127 devices.

Panels Available as a loose controller or pre-mounted in a service panel with the transformer and terminal blocks already installed. Two-controller panels ship today; three- and four-controller panels are coming, which is how you would land a couple of ZoneQs in one enclosure. The panel with the HMI display is not released yet — it was still in cyber testing as of the 9/2026 training, targeted for end of year.

The full lineup

SkyQ hardware — everything hangs off the NC2000 network controller. Bosch SkyQ deck, rev. 8/1/26.

Part	What it is	Use it when
NC2000	Network controller / gateway	Always. One per system.
SEC / SSE / UCB	Smart Equipment Controls already on our units	Direct integration — set the COM card to Modbus and wire in.
ZONEQ	Zoning controller for Smart Equipment multi-zone	Any multi-zone job on our own equipment — VAV or changeover bypass.
BAC‑EQB	BACnet equipment bridge	Third-party unit that already has a BACnet MS/TP card.
M2000‑RTU / ‑HP M2000‑RTUS / ‑HPS	Application controller for third-party equipment	Third-party unit with no card. Up to 4 cooling stages; you add the sensors.
M2000‑FLX	Flexible I/O controller	Anything that is not a packaged unit — exhaust fans, pumps, lighting, reheat.
VC2000	Zone controller (zone damper / VAV box)	Every zone. Pressure-independent or pressure-dependent versions; with or without pressure ports.
VC2000‑BYP	Bypass damper controller	Changeover bypass systems only — dedicated part number for the bypass damper.
TREE‑COM	Wireless adapter	When a run cannot be wired. 2,000 ft line-of-sight; several hundred feet realistically.
485‑BT	Service tool (Bluetooth or wired)	Not required, but it is how the mobile app connects on site without cloud.
T1000 wall sensor	Zone wall sensor with display	The common pick for zones on our equipment. A full-touchscreen replacement in black or white is coming.
Thermostat coming	2-stage thermostat for simple third-party units	Not released. Up to 2 stages, no economizer control. Targeted end of 2026.

Reading an M2000 part number RTU or HP tells you rooftop or heat pump; FLX is the flexible I/O version. A trailing S means single zone — M2000‑RTUS is single-zone, M2000‑RTU is multi-zone. Get that letter wrong and you have ordered the wrong logic.

Coming From Verasys

Mapping, migration and the hard limit

Most of this team has Verasys hours. The device-for-device mapping is clean; the protocol change is the thing that will bite you.

Verasys → SkyQ, device for device

Verasys (discontinued) against SkyQ, role by role.

Role	Verasys (discontinued)	SkyQ
Gateway	SBH300	NC2000
Thermostat	TEC3000	T xxxx coming
Wall sensors	NS8000	S xxxx coming
RTU controller	SSE / VEC100 (3rd party)	SSE / M2000 (3rd party)
Zone coordinator	VZC100	ZONEQ
Zone controller	ZEC310 / ZEC510	VC2000
Application controller	VAC1000	M2000‑FLX
Wireless	TMR100	TREE‑COM

You cannot mix the two

Hard limit SkyQ runs Modbus. Verasys ran BACnet MS/TP. You cannot drop a SkyQ device into a Verasys system or a Verasys device into a SkyQ system. There is no adapter. A site is one or the other.

Verasys parts stay stocked for replacement and limited expansion for seven years, and Verasys tech support stays with Johnson Controls at 866‑663‑6105 or be-verasyssupport@jci.com. So an existing Verasys site is not an emergency — but every expansion beyond what JCI still stocks is a conversion conversation.

Swapping an old YCCS or Verasys site to SkyQ

The good news: the wiring stays. A previous YCCS or Verasys system converts using the same cable.

Pull the wire off the SEC controller — the one that ran to the first zone controller — and re-route it to the ZoneQ. That single move is the structural change: Verasys ran the zone bus off the equipment, SkyQ runs it off the ZoneQ.
JCI NS sensors can stay for single-zone applications. Leave them on the wall and reuse the wiring.
Every other device gets swapped. Zone controllers, coordinators, application controllers, the gateway — all of it.

What changes structurally: Verasys ran the zone bus off the equipment, SkyQ runs it off the ZoneQ.

Single-Zone

Three paths

1 · Our Smart Equipment — wire straight in

Set the unit’s COM card to Modbus and land it on the interface bus. There is no intermediate controller.

Auto-recognizes the SEC controls — no device type to pick.
Graphics build themselves to match how the unit is configured.
Full SEC menu access — the same menu tree you know from GoTempPro or the MAP tool.
Alarms and notifications from the unit route through the NC2000.
Use an NS8000 wall sensor, not a thermostat.

Why this is the easy sale Hundreds of points come across with no mapping, no graphics work and no commissioning of the front end. That is the part Prolon’s own system cannot do on our equipment, and it is the whole argument for pairing SkyQ with our rooftops.

Single-zone on our Smart Equipment — wire the COM card to the NC2000, add an NS8000 sensor.

2 & 3 · Third-party equipment

BAC‑EQB — the unit has a BACnet MS/TP card. One communication wire, then a discovery that lists every point the unit exposes; you pick up to 32. Existing wall sensors can stay where they are.

M2000‑RTUS / ‑HPS — no card. Wires up like a thermostat and controls the unit like one, up to 4 cooling stages. You must add return, supply and outside-air sensors, plus a SkyQ wall sensor.

Coming, not here The 2-stage thermostat is the third path — simple units, up to two stages, no economizer control. It was not released as of the 9/2026 training; targeted for end of 2026. Do not quote it yet.

Single-zone third party — the three paths, and what each one wires to.

Multi-Zone

ZoneQ, VAV and changeover bypass

Our Smart Equipment — the ZoneQ

The ZoneQ is the piece that makes multi-zone work on our own units. It has two separate terminals: one back to the main interface network, one out to the zone controllers.

Provides both the integration and the zone control — you do not need an M2000 as well.
Auto-recognizes the SEC unit, graphics match the configuration, full menu access, alarms — same as single-zone.
Zones use SkyQ VC2000 controllers and SkyQ wall sensors. Third-party wall sensors do not work here.
Handles both VAV and changeover bypass.

Against Prolon Prolon has to put an M2000 on a zoning job because that is where their zoning logic lives. On our equipment we use the smaller, cheaper ZoneQ instead. Same outcome, less hardware, less labor.

Multi-zone on our Smart Equipment — the ZoneQ sits between the unit and the zone controllers.

How changeover bypass actually decides

Worth understanding before you sell it, because it is the question a contractor will ask. The ZoneQ does not pass zone temperatures to the unit — it simulates a control temperature to tell the unit what mode to run and how hard.

It takes a weighted average of the heating demand and of the cooling demand across all zones.
It drives the simulated temp up to 9°F above the cooling setpoint to signal 100% cooling demand, and 9°F below the heating setpoint for 100% heating. Both are adjustable — tighten them to make the unit react faster.
Negative aggregate demand = cooling mode; positive = heating mode.
When heating and cooling conflict, cooling wins by default. Configurable per building.
Individual zones can be weighted as critical, or ignored entirely.

Defaults are good Most people set it and forget it. The flexibility is there, and it is deep enough to get someone in trouble — there is no reason to touch the math on a normal job.

Third-party multi-zone

Same two options as single-zone, same rule for choosing between them: BAC‑EQB if the unit has a BACnet card, M2000‑RTU / ‑HP if it does not. The zoning logic is built into both. There is no limit on VAV boxes per unit beyond the 127-device ceiling on the trunk.

Multi-zone third party — BAC-EQB where there is a card, M2000 where there is not.

Third-Party Equipment

BAC-EQB vs. M2000

Choosing between them

	BAC‑EQB	M2000
Requires	A BACnet MS/TP card on the unit	Nothing — works on any unit
Wiring	One communication wire	Thermostat terminals, plus sensor wiring
Sensors	None added — uses what the unit has	Return, supply and outside air must be added
Existing wall sensors	Can stay on the wall	Must be replaced with SkyQ sensors
Points	Up to 32 exposed points, hand-picked from a discovery list	Whatever you wire and sense
Staging	Whatever the unit exposes	Up to 4 cooling stages
Cost & labor	Lower on both	Higher on both

Worth knowing One BAC‑EQB can pull in up to three units if you need it to, but the normal design is one per unit. And “32 points” means 32 points for that unit, chosen from however many hundred it exposes — not 32 units.

BACnet/IP and supervisory systems

No MS/TP only. There is no BACnet/IP and no conversion tool. SkyQ is not designed to integrate into a supervisory system. If a job has a BAS that wants to see this equipment, SkyQ does not get you there.

The four-stage question

You can do four stages through the M2000. But if you are ordering the unit anyway, a BACnet card is cheap and the BAC‑EQB path is far less labor than wiring an M2000 and hanging sensors. If the customer insists on a four-stage stat like the Honeywell TC500, that can be pulled in through the BACnet bridge too.

Wiring, Limits & Wireless

The numbers to quote against

The trunk

Protocol: Modbus, at 57,600 baud.
Wire: 24‑AWG twisted two-conductor, shielded.
Topology: daisy chain on the interface bus (INT). The zone bus (NET) is a separate trunk off the ZoneQ.
Ceiling: 127 devices per NC2000 — a Modbus addressing limit.

What counts toward 127 Anything with an address. Smart Equipment units, zone controllers, bridges, thermostats — all of it. Wall sensors do not count (a thermostat is a controller; a wall sensor is not).

Configurator still says 100 Sel Nav’s SkyQ configurator displays a 100-device limit and estimates 15 zones per unit. Both are relics from Verasys and were known-wrong as of 9/2026. The real number is 127.

System summary — every application on one trunk. Up to 127 devices, Modbus, 24-AWG twisted shielded pair.

Wireless (TREE-COM)

2,000 ft line-of-sight. In a real building with obstructions, expect several hundred feet.
They come in pairs, minimum. A wireless link needs a puck at each end — one on the NC2000 and one on the device. A fully wireless job means a puck on every single device.
Each board still needs 24V power locally. Only the communication goes wireless.
Works on either bus — the interface bus or the zone bus — and you can use it in just the one spot that is hard to wire rather than everywhere.

How to position it Wire it if you can. Wireless is there for the run that genuinely cannot be pulled, and it is proven — the Wichita branch runs five rooftops on it — but a wired trunk is the one you never get called back about.

Software

Desktop, mobile, cloud — all free

You only pay for hardware

Desktop, mobile and cloud access are free, with no license and no subscription — and the software keeps getting iterative updates. That is a real talking point against anything with a recurring fee.

App	Platform	Best for
Desktop	Windows and macOS	Setup and commissioning. Prebuilt graphics that adapt as you configure; upload a photo or floor plan and overlay a tile per device.
Mobile	iOS and Android	Day-to-day checks and notifications. Connects on site through the 485‑BT service tool over Bluetooth, or from anywhere through the cloud.
Cloud	Any browser-capable device	Remote access. NC2000 talks RS‑485 down to the devices and TCP/IP up to the cloud.

Desktop, mobile and cloud. The only thing you buy is the hardware.

What it actually looks like

Click any image to enlarge it.

Upload a photo or a floor plan and overlay a live tile per device — a roof shot, a CAD plan, a 3D rendering.

The desktop app: a zoning heat pump on changeover bypass, with the unit graphic built from its own configuration.

Drilling into one VAV controller — damper position, duct heater, zone demand and setpoints.

The mobile app: system view, a zone controller, the SEC rooftop, and the commissioning quick-start menu.

Two things people notice immediately

Discovery is fast. The single loudest Verasys complaint was discovery taking 45 minutes or more on a big system. SkyQ pulls in quickly and moving between menus is snappy.
Templates. Configure one VAV box — settings and graphics — save it as a template, and apply it across the other nineteen identical boxes instead of repeating yourself.

No search There is no search box inside the software for finding a point by name. With hundreds of integrated points that would be useful; it has been raised with the factory.

Selecting & Quoting

Sel Nav, and the trap in it

The walkthrough

Select the units first, with the SkyQ control option on them. See the warning below — this is the step everyone misses.
In the job, Add Product → SkyQ Controls. It sits at the end of the rooftop list, because it is part of the rooftop business.
Pick the network controller — loose, or in a panel with the transformer and terminal blocks.
Add accessories such as the 485‑BT service tool.
Build it out system by system. For each one choose the application (single-zone, changeover bypass, VAV, third-party), then pull in a unit you already selected or select a new one inline.
Add the zone hardware — bypass controller, zone dampers, and a wall sensor for every zone.
Add power — pick the transformer that covers the controllers you just added.
Review the estimate. Data sheets and generic riser drawings come with the network controller.

CFM shortcut The SkyQ selection exports to Excel from Sel Nav and drags straight into the vendor-quotes tool — tested 9/2026, it picks it up immediately. You do not have to re-key the bill of material.

The trap: the unit needs the SkyQ control option

Do this or the configurator will not see your units On each rooftop, go to the control option and pick the SkyQ choice. If you skip it, “currently saved unit” comes back empty in the SkyQ configurator and it looks broken.

Selecting it changes the unit’s model number — it is its own configuration.
Physically the unit is identical. All it does is set the communication protocol to Modbus and the baud rate to 57,600 at the end of the line, so it is ready to wire.
There is one SkyQ option in the list. On a VAV unit it is still the one to pick.
Any of this can be done in the field instead — you can take an old R‑410A unit, add a COM card, set it up and pull it in.

Known configurator quirks (as of 9/2026)

Nothing checks your sensor count against your zone count. Five zones does not force five sensors. Count them yourself.
It is easy to add a duplicate ZoneQ. A ZoneQ comes with any multi-zone Smart Equipment application — if you also add one by hand you will see two on the estimate.
Direct entry does not port into the configurator. Pick one method per job. Direct entry is fine once you know the part numbers cold.
The 100-device and 15-zone figures on screen are wrong — see Wiring & Limits.

Check the estimate line by line The configurator is a step in the right direction, not a guarantee. Read the bill of material before it goes out.

Submittals

Data sheets for each device and generic riser drawings come with the network controller selection. For a real job, contact the application team for a submittal packet drawn for your specific system — that is currently how nearly every job goes out. David Cole handles SkyQ selections; if you call or email commercial sales support about SkyQ, it reaches him.

Ordering & Lead Times

Fast, and that is the problem

How an order flows

Order through Navigator.
It goes to CFM purchasing, then to the factory.
The factory places it with Prolon, who drop-ship to the site.
It typically ships within three to four business days of the order landing — inside a week, consistently. Prolon stocks every component and stock is deep.

Stock is not visible to us SkyQ stock levels are not in Solution Navigator, because a third party holds the inventory. As of 9/2026 there was no shortage of anything and no plan to expose levels until volume justifies it.

Two things to get right on every order

Split the controls off the rooftop order Controls arrive in a week; the rooftop takes twelve or more. Put them on the same order and the controls turn up months early and sit somewhere. Order them separately — or on new construction, use it deliberately: the dampers can be on site long before the units.

Ship to the contractor’s shop, not the job site These are small parcel shipments — UPS, sometimes Purolator — not a flatbed. Thermostats and controllers showing up loose at a job site is how they go missing. Shipping to the shop also lets a contractor bench-wire the system, configure it and get familiar before it ever goes in the building, which several already do.

Zone dampers may differ. They come from a different supplier than the controllers, so do not assume the same lead time — confirm it when a job hinges on the date.

What you cannot order yet

The 2-stage thermostat — targeted end of 2026.
The pre-assembled panel with the HMI display — still in cyber testing, targeted end of 2026.

Everything else on this page is orderable today.

Training

Two-day hands-on technical training at Comfort Academy (formerly Ducting Systems Academy). One was being scheduled for October — open to us and to contractors.
There is no web-based installer training yet. For now it is the startup and quick-start documents, or the classroom.
A contractor-focused version of the sales training can be arranged — the content overlaps, the questions do not.

Firmware

Updates exist but are rare — these controllers do simple things. Occasionally one adds functionality or fixes a bug. If a system is working, there is no obligation to go update anything.

Rep FAQ

Straight from the training

Questions the team actually asked

Can I get this into a BACnet/IP or building automation system?

No. MS/TP only, no conversion tools, and SkyQ is not designed to integrate into a supervisory system. Qualify for this early.

Is “32 points” per unit or across the system?

Per unit. You run a discovery, see every point the unit exposes — often hundreds — and pick the 32 you want. One BAC‑EQB can serve up to three units if pushed, but design one per unit.

M2000 or M2000‑FLX?

The plain M2000 controls a packaged unit like a thermostat. The FLX is a generic I/O controller for everything that is not a packaged unit — exhaust fans, pumps, lighting, SCR reheat — and there are boiler and simple chiller applications available for it too.

A customer already buys Prolon. What is different?

Pricing should be similar. The difference is integration on our equipment: Prolon wires their controller up like a thermostat and sees the points they add, so they get a fraction of the data and have to build graphics. We connect to the COM card and get hundreds of points with the graphics already drawn. On zoning, they need an M2000 for the logic where we use the smaller ZoneQ.

On third-party equipment we are in the same boat they are — same bridge, same discovery, same manual work.

The hardware is the same family under different colors and branding, so a contractor familiar with Prolon will navigate SkyQ easily. The two do not interoperate — Prolon controllers cannot get the integration on our units.

What about a site that is half ours and half somebody else’s?

That is the best scenario you can walk into. Once the customer sees how much comes across on our units against the trickle from the third-party ones, replacing the rest becomes an easy conversation.

Does it work with Sun Premier?

As a third-party device for now — BAC‑EQB, up to 32 points. Full integration is targeted for roughly mid‑2027, and the groundwork done on SSE should make it more straightforward. Worth setting expectations on a large Premier job.

Can I pull in a residential split or something odd?

Through the third-party path, yes — the same rules apply.

Do wall sensors count against the 127 devices?

No. Anything with an address counts — controllers, bridges, thermostats. A wall sensor has no address.

Can I put SkyQ on an older unit we already sold?

Yes, if it takes a COM card. Add the card, set it to Modbus at 57,600, and pull it in like any Smart Equipment unit. Both R‑410A and R‑454B Smart Equipment work.

Am I going to get firmware-update callbacks?

Rarely. Updates are infrequent and optional on a working system.
