Secondary Terminal Controller

  • California Prop 65


Product-Integrated Controller

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



Application Features

  • A library of sophisticated factory-engineered and tested control programs provide reliability and energy efficiency
  • Programmable zone level control of terminal units, fan coils, lighting, exhaust fans and more
  • Supports advanced control routines for zone level humidity control or zone level demand control ventilation (ASHRAE® 62)
  • Supports Carrier communicating space sensors and touch screens which allow for local setpoint adjustment and local overrides
  • Quick and easy test & balancing process

System Benefits

  • Integrated Carrier airside linkage algorithm for plug-and-play integration with Carrier air sources
  • Fully plug-and-play with the Carrier i-Vu Building Automation System
  • Supports demand limiting for maximum energy savings
  • Supports dual duct applications when used with Carrier’s VAV Zone II Secondary Terminal Controller

Hardware Features

  • Separable brushless actuator for reliability and longevity
  • Capable of system or stand-alone operation
  • Native BACnet MS/TP or ARCNET communications
  • Controls up to 8 points (3 binary outputs, 4 universal inputs and 1 analog output)


BACnet Support Advanced Application Controller (B-AAC), as defined in BACnet 135-2012 Annex L Protocol rev. 9
Communication Ports BACnet Port: EIA-485 port for BACnet MS/TP communications (9600 bps, 19.2 kbps, 38.4 kbps, & 76.8) or ARCNET 156 kbps;
Local Access Port: For system start-up and troubleshooting (115.2 kbps)
Rnet Port: For connecting Carrier communicating room sensors and Carrier’s touchscreen user interface
ARCnet Port: For connecting the actuator cable
Separable Actuator Brushless DC motor, torque 45 inch-pounds (5Nm), 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 4 inputs: Configurable for thermistor or dry contact. Inputs 1 and 2 are also configurable for 0–5 Vdc 10 bit A/D resolution. Binary input pulse frequency 10 pulses per second. Minimum pulse width (on or off time) required for each pulse is 50 msec
Outputs 1 analog output:0 to 10VDC (5mA maximum) with 8 bit D/A resolution using filtered PWM
3 binary outputs: Relay contacts 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 or ARCnet address of controller.
