how do I wire lux pspa722 to control a pump relay? I have 110v power to the relay and 24V power to the LUX thermostat. If I disconnect the thermostat and bridge the thermostat terminals on the relay the unit works. It also woks if I disconnect the wires from the thermostat and bridge them at the other end. Therefor I know the wires are intact and also that the relay is working correctly.
