The ZCV series of HVAC Zone Control Units includes 2 and 4 zone controllers. The units allow a single HVAC mechanical system to be divided into fully independent zones. Zone control is accomplished with individual “thermostats” or temperature sensors in each zone and motorized zone dampers to control the flow of air to each zone.

Each zone “thermostat” is a RCS Wall Display Unit (WDU) or a zone temperature sensor. The Wall Display Unit looks like a traditional thermostat and is the wall mounted user interface for each zone of the ZCV controller. It provides visual display of temperature, setpoints and modes, the control pushbuttons, and the zone temperature sensor. The WDU’s connects to the Zone Control Unit by a 4 wire cable, which can be existing thermostat wires in retrofit applications or Category 5 wiring in new construction.

The Zone Control Unit connects to the HVAC system at its standard thermostat connections. Electrically, it functions just like a regular thermostat to the HVAC system, provides the thermostatic control of each zone and sends the appropriate heating and cooling calls to the HVAC mechanical system.
