1. From VVT to 3V
The move from VVT to 3V is the same quantum change in HVAC applications as the move that Constant Volume applications made when VVT was introduced.

The old Temp system could provide Constant volume applications, but were limited to one type of sensor 3V system is not limited to a single sensor.
The move from constant volume application to a VVT application with the old VVT system required significant controls change outs the Temp stat to a monitor stat and possibly a Relay pack. The 3V system can seamlessly transition for a constant volume application to a VVT application without the loss of expensive controls.
They 3V systems devices can work with Factory VAV package rooftop units equipment controlled with PremierLink or ComfortLINK. In addition the 3V system works in conjunction with Carrier ComfortID zone control devices

This is a typical Temp system.
Requires a Relay Pack and a Temp stat (with at least one clock)
There is wiring for the sensors, to the unit, the Temp stat and CCN communication. All allowing more chances of installation problems.

The NEW 3V system is less complicated.
The CCN communications is between the PremierLinks and not the sensors in the space.
There are more the just one sensor type that can be put into the conditioned space. You have the choice of the T55, T56, T59 (digital display), T55/CO2, T56/CO2 or the System pilot.
Only sensor wiring has to be dropped for the T55 and T56. There is additional power and sensor wiring for the T56/CO2. The System Pilot requires just the CCN wiring and power.
In addition, all these sensor are compatible with all other Carrier controllers. Like the PremierLink, ComfortLINK, the 1600 and 6400 Comfort Controllers as well as the new Universal Contoller.

5. Sensor Choice Flexibility
The 3V system now allows for the use of any of the many Carrier sensors. The T55 is not shown, but can be used.
These sensors can be used for both the 3VZone controllers, the ComfortID Zone Controller and on the NEW Universal Controller.
It allows for more consistent sensor appearance and application.

6. Gen III vs. 3V 3V 3V Zone Gen III Zone Easy Mount & Access
Monitor 3V
3V has reduced the complexity but has increased flexibility. 3V is simple to wire,install, and set-up.
Look at all the components the GEN III VVT system required vs. the New 3V System. Look at to sensor options not available before vs. now.
Zone
Choice of Sensors

7. Zone Features Damper Position Infinite damper positions
Separate cooling and heating limits
Supports 30° - 90° actuator travel
The new 3V Zone controller provides for a single actuator to do 30° to 90° travel applications. Less mix-ups on the job. This 3V zone controller provides a very clean retrofit installation with easy access to the controller actuator as well as all the wiring connection.
We will talk later about the ability to use third party actuators as well as the ability to link up to (4) damper actuators together.
All limits are in percent NOT 1 to 15 damper Positions. Easy to change values to meet job requirements
Min/max cooling positions
Min/max heating positions

8. Gen III vs. 3V 3V 3V Relay Pack Linkage Air Source Gen III Bypass
3V Bypass w/ Transducer
Bypass Controller
The GEN III VVT used one of two relay packs to control the air source. The new 3V system uses the PremierLink for both retrofit as well as factory installation. In addition the 3V system will work with the ComfortLINK controller. Both of these new controllers provide more features and benefits the the old Relay Pack could.
The GEN III VVT Bypass controller system required 3 components. The bypass controller, the Actuator assembly and the pressure sensor. Very complex installation, setup with a lot of wiring to go wrong.
The 3V system extremely simple in that it is an all in one application product. Damper actuator, Pressure sensor and Bypass controller. A 3V

9. Bypass Features Bypass Controller System or stand-alone operation
Infinite damper positions
Integrated pressure sensor
Built-in equipment and system protection
Determines system mode with PAT and pressure sensor if air source communication fails
LAT protection
Configurable increase in pressure setpoint for high or low LAT

10. Actuator Options Larger Bypass Actuators
Higher torque actuators available
Rewire control signal and feedback potentiometer to new higher torque actuator
0 to 10 vdc feedback
The old VVT bypass controller system was not flexible enough to allow for the use of other dampers. The 3V bypass controller can control other actuators with feedback.
Floating point control
Feedback potentiometer

11. Air Source Control Features

To add Supplemental heat to any zone is extremely simple. Requires the addition of the Optional Supplement Heat board to any zone controller. The wiring for this Optional Supplement Heat board allows for control of Staged electric heat, Two Position valves as well a Floating point controlled valves.

13. Zone Features Supplemental Heat
Ducted and non-ducted heat types include:
2 position
Up to 3 stages
(NEW) Floating Point
(NEW) 2 position baseboard w/ ducted staged heat
H C
This Optional Supplemental heat board is extremely flexible. A very powerful option to allow the 3V system to meet any jobsite requirements for addition heat.

14. Actuator Options Linked Actuators Zone or Bypass Controllers
Up to 4 additional actuators
Dedicated output for linked actuators
0 to 10 vdc control
0 to10 vdc feedback
Requires 24 VAC power (locally or on VVT damper)
The GEN III VVT system would only allow for VVT actuators to be controlled by the VVT zone controller. The GEN III VVT system did allow for the addition of up to 4 damper actuators.
The 3V systems allows for the for 4 additional actuators to be controlled off the zone controller.
