Description
The Resideo R8845U1003 is a multi-system switching relay designed for hydronic heating systems and is highly flexible. It uses a 24V coil voltage and an internal transformer for consistent switching control of HVAC loads such as boilers, circulator pumps, and zone valves. This relay controls the flow of electricity and makes certain that other devices that are connected to it work efficiently. It has two operations of the SPST (Single Pole Single Throw) switch. Included with the R8845U1003 is an enclosure that will protect the relay and make installation easier; UL and CSA ratings ensure that the relay conforms to safety standards and 2-wire and 3-wire control circuit compatibility make for easier system design.
