1. When power is provided to the 120V terminals connected to the power module
1
, the transformer provides 24V power
to the StatLink® Base Module.
2. When the thermostat calls for heat, its internal 24V contacts close, the StatLink® Base Module dry contacts

close, and
the pump

turns on. If actuator(s)
