The controller is capable of controlling from two to twenty individual zones. The System Controller communicates with the Zone Dampers and Zone Thermostats via a patented Five-Wire Link. The Five-Wire Link is daisy chained from damper to damper using standard five-conductor thermostat wire. The System Controller polls every zone and registers the number of thermostats calling for heating and cooling. The System Controller then runs the HVAC unit in the mode with the most calls. If the majority changes, the System Controller will automatically change over to the new mode of operation.
