Relay for heat source (illus. 10)
Boilers/heat sources can be controlled via the heat source relay. The relay is located under the lid of "high
voltage side" of the receiver unit.
NOTE: the relay contact is "potential free" (volt free), which means that the boiler relay contacts must be
powered from an external source and NOT from the receiver unit. The boiler/heat source will fire approximately
6 minutes after any one channel calls for heat. When the relay is activated, the Boiler LED is lit.
NOTE: wiring/connection to the relay may only be performed by a qualified electrician. See diagram below.
