Power on 1 and 2 indicate the grey relay is closed by turning on the electric switch and is conducting power to the thermostat.
Power on 3 and 4 indicate the thermostat is conducting.
No power means the grey relay is not conducting or the control thermostat is stuck open.
I am traveling but would be happy to talk on phone while you perform these tests at 713 8 one 8 3 two 34.
