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.

Variable Volume Variable Temperature Packaged Variable Air Volume The Flexible 3V CV Constant Volume VVT Variable Volume Variable Temperature PVAV Packaged Variable Air Volume 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

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. CCN Communication Temp Stat with Time Temp Stat without Time

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. 24vac 40va T55/56 T59 Digital CO2/T55/56 (Optional for DCV) (See Note 2,4) System Pilot

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. Dual Sensor Temp & CO2 Best! Good! Better!

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

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 Vent position Reheat position

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

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

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

3V Zone Controller 3V Zone Controller New Plastic 1 piece base Removable, hinged covers Larger opening for wiring ease Integrated Belimo 35 in/lb actuator Controller Boards Removable power and comm connections Option board for heat and fan snaps into place 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.

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.

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. 0-10vdc control signal 24VAC Power

Must Replace Entire Gen III Zone with 3V! 3V Compatibility with Gen III 3V Zone VVT GEN III System 3V – VVT zones respond to Gen III Monitor Scan. However, the GEN III VVT zone controllers will not respond to New 3V Zone Controller Linkage Coordinator. Address 3V Zone controller in the GEN III VVTT monitor’s scanning range Entire replacement zone will consist of a 3V Zone Controller and System Pilot for set-up and temperature sensor. (or just a Zone controller and a sensor – T55,T55 or T59) Must Replace Entire Gen III Zone with 3V!
