120vac
This is a typical layout of the old GEN III Temp type system, but using the NEW 3V PremierLink and all the associated sensors.
Notice the simplicity in the wiring installation.
Notice the different sensor applications
Notice the the use of System Pilot and the CCN bus to send information to PremierLink
Please note the power transformers and their usage. The T56/CO2 requires a separate transformer. Extreme caution needs to be taken if sharing the same transformer with other devices. Improper wiring may cause all devices to fail.

CCN Communicating RTU
This is the New VVT System.
Note there is NO Monitor Stat in this system! There is a device the is assigned the Linkage Coordinator that will communicate with the PremierLink or ComfortLINK. Any Zone Controller can be configured to be a Linkage Coordinator
There is NO direct control wiring between the Linkage Coordinator and the PremierLink like the Monitor Stat and Relay Pack. All communications between the linkage coordinator and PremierLink are done on the CCN bus.
Notices that only the sensors are in the space. No longer is the expensive controller in the space in harms way.
You have a choice of space sensors: T55, T56, T59 (digital), T55/CO2, T56/CO2 and the System Pilot.
The Bypass Controller is NOT in the middle of list of Zone Controller like in the GEN III VVT.
It is addressed 1 higher then the Linkage Coordinator, not 1 lower then the monitor stat of the GENIII VVT system.
Notice that for the Bypass Controller there is NO additional devices in the space. The Bypass Controller is one device with Actuator, Pressure Sensor and Controller to make it a complete module all mounted on the bypass damper.
Explain PAT, SAT and DAT Sensors.
All zone controller use Error Reduction Control Logic.

4. Typical 3V VVT System Notes
239 devices maximum per bus. Repeater required every 1000’ or 60 devices. Maximum of 3 repeaters per bus.
Communication bus and sensor wiring MUST be separate from AC power wiring
Maximum of 8 Masters per bus.
Combination CO2/T55/T56 sensor may be used in place of T55/56 on any zone requiring DCV. RTU must be capable of controlling economizer for DCV conditions.
Locate PAT in supply air duct from air source unit.
Review Addressing issues and the bypass is 1 up not 1 down like GEN III VVT
Add to this the Mark Sparling 30 address between the Linkage Coordinators.
Also Only 128 3V Zone Controller on a bus.

This is a Pressure Independent application.
The 3V VVT system is Unlike the old GEN III VVT where you had to order a special Zone Controller, and a pressure sensor.
For Pressure Independent applications all you have to do in use a ComfortID Zone Controller with a velocity pickup.
There is still the need for a 3V Bypass Controller and a 3V Zone Controller (with not associated damper) setup as the Linkage Coordinator to talk to the PremierLink or the ComfortLINK Controller.
The 3V Linkage Coordinator can communicate with the ComfortID Zone Controllers.
The ComfortID Zone Controller will use the same space sensors as the 3V Zone Controllers. You have a choice of space sensors: T55, T56, T59 (digital), T55/CO2, T56/CO2 and the System Pilot.

6. 3V VVT Pressure Independent Only System Notes
239 devices maximum per bus. Repeater required every 1000’ or 60 devices. Maximum of 3 repeaters per bus.
Communication bus and sensor wiring MUST be separate from AC power wiring.
Maximum of 8 Masters per bus.
Combination CO2/T55/T56 sensor may be used in place of T55/56 on any zone requiring DCV. RTU must be capable of controlling economizer for DCV conditions.
Locate PAT in supply air duct from air source unit.
VVT controller only is required for Master functions if all zones are pressure independent.

Supplemental Reheat:
Any 3V Zone Controller can have supplemental reheat added. Every the linkage coordinator.
These are some examples of supplemental reheat.
Ducted heater should have a Supply Air Sensor (SAT) down stream of the duct mounted heaters.
There can be:
Staged Electric
Two position hot water or steam
Floating point hot water Duct or baseboard.
Fan and staged heat.
This is a very flexible system that will meet all jobsite requirement and even provide a spec stopper.
All supplemental reheat control use Error Reduction Control Logic.
