Relays & Zone Valves

Pump switching relays control the operation of a single circulator or pump from a 24-volt signal. Relays include secondary low-voltage terminals for boiler operation. Radiant heat zone valves feature 3/4- and 1-inch sweat connections, and provide flow control for a single-zoned radiant heat manifold (manifold serving one zone). This category also contains zone control modules, which are printed circuit control and diagnostic devices designed for use with Wirsbo thermostats, motorized valve actuators (MVAs), thermal actuators or zone valves.
