4-Zone Master Valve/Actuator Control

Master Valve/Actuator Controls are intended to control Watts Radiant Electrothermal Actuators, or any 24-VAC actuator or valve that draws 5 VA or less. The number of actuators controlled depends on the separate 24-VAC external transformer (not supplied) powering the system. An external 40-VA 24-VAC transformer can control 12 actuators maximum. Up to 18 actuators maximum can be controlled with a 60-VA 24-VAC transformer. However, the physical limitation of the Control itself is three actuators per thermostat connection. Order Slave Valve/Actuator Controls separate for additional zones. Master Controls are fused and include two end switches, each rated at 8A. Actuators are switched by triacs, for quiet, safe, reliable electronic operation. Mounting is by DIN rail or surface mount to a wall.
