Product Integrated Controller
The VVT Zone II controller provides zone level temperature and air quality control for a variety of pressure-dependent VVT applications. This advanced controller features a separable actuator for easy installation onto single duct and parallel fan-powered air terminals. It also features native BACnet communications and plug-and-play connectivity to the Carrier i-Vu Building Automation System.

|Separable Actuator||Brushless DC motor, torque 45 inch-pounds (4Nm), runtime 205 seconds for 90 degree travel during control.|
|Integral Pressure Sensor||Precision low flow AWM series O-2 in H2O, sensitive down to +/-0.001 in. H2O. Barbed tapered airflow connections accept 3/16 in. (4.75 mm) ID tubing. Allows for readings across the 0-2 in H2O range, accurate to +/-5% of full flow at 2 in. H2O.|
|Inputs||3 analog inputs: RH/CO2 (0-5V), T55 (10k thermistor), SAT (10k thermistor). AIs have 10 bit A/D resolution.
1 binary input: Remote Occupancy (dry contact).
|Outputs||1 analog input:Hot Water Valve (HWV). AO is 0 to 10VDC (5mA maximum) with 8 bit D/A resolution using filtered PWM.
3 binary outputs: HEAT1, HEAT2, and FAN. Relay contact rated at 1A max @ 24VAC/VDC, configured normally open.
|Protection||Incoming power and network connections are protected by non-replaceable internal solid state polyswitches that reset themselves when the condition that causes a fault returns to normal. The power, network, input and output connections are also protected against voltage transient and surge events.|
|Battery||10-year lithium CR2032 battery provides a minimum of 10,000 hours of trend data retention during power outages.|
|Status Indicators||LED status indicators for BACnet MS/TP communication, run status, error, power and all digital outputs|
|Controller Addressing||Rotary DIP switches set BACnet MS/TP address of controller.|
