Switching Relays

Zone relays provide simple installation and interface between the thermostat and the boiler. Convenience and reliability in one package!

R8146

R8146

The heating relay isolates a self-generating millivolt (PowerPile®) heating control system from the low voltage cooling control system.

R845

R845

Switching Relay provides DPST switching for hydronic zone controlled heating systems or SPST control of two separate loads. One load must be line voltage; the other may be either line or low voltage.

R847

R847

Designed for control of relatively heavy duty 120 or 240 Vac electrical loads such as cooling compressors.

R856

R856

Provides 24 volt control of line voltage motors, fans, blowers, or pumps up to 1 hp.

R8845

R8845

The R8845U Universal Switching Relay with 24 V transformer provides intermediate switching of line-and low-voltage devices from a line- or low-voltage controller and is typically applied in Hydronic heating systems.

RA832

RA832

Provide intermediate switching of a line voltage device from a low voltage controller.

RA889

RA889

The RA889A Switching Relay with 24 V controller provides intermediate switching of line- and low-voltage devices from a line- or low-voltage controller and is typically applied in Hydronic heating systems.

RA89

RA89

Provide intermediate switching of a line voltage device from a low voltage controller.
