The heating relay isolates a self-generating millivolt (PowerPile®) heating control system from the low voltage cooling control system.
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.
Designed for control of relatively heavy duty 120 or 240 Vac electrical loads such as cooling compressors.
Provides 24 volt control of line voltage motors, fans, blowers, or pumps up to 1 hp.
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.
Provide intermediate switching of a line voltage device from a low voltage controller.
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.
Provide intermediate switching of a line voltage device from a low voltage controller.
