Watts Radiant introduced a zone valve/actuator control designed to operate zone valves or circuit thermal actuators. Master controls are equipped with valve and thermostat terminals, incoming 24 volt power connection and two 8 amp, dry contact terminals for pump and boiler operation. Up to two Slave controls can connect to a Master, allowing for a maximum of 18 separate zones or thermostat connections. This system can be used with Watts Radiant DualTemp (3 or 4 wire) and Air Only thermostats or any two-wire thermostats with internal battery power.
