The ZON-0500 is an intelligent, microprocessor based zone control. Capable of controlling up to 4 zones per control, the ZON-0500 can be used as a standalone unit and can handle multiple priority selections. 

The controller can be daisy-chained to provide unlimited coverage and flexibility for virtually any number of zones. The ZON-0500 allows for pump or zone valve control, and is capable of enabling a boiler, heat pump and DHW tank.

The control is compatible with most 2,3 or 4 wire thermostats.
