Tekmar Switching Relays

Tekmar circulator switching relays are controls which connect thermostats with circulator pumps to create multi-zone heating systems. All models from 2-Zone and up have features such as priority (for providing heat to an indirect domestic hot water heater tank), optional exercising (prevents circulator seizure when not in use) and optional post purge operation (of the last operating zone - to maximize energy savings). Tekmar relays also introduce a RoomResponse signal to mod-con boilers to optimize their efficiency. All models are expandable with no additional components needed and are compatible with Taco, Grundfos, Armstrong, Wilo and other brands of circulators.
