Hi, i'm new here and desperately need some assistance. I have multiple lennox heat pump and AC systems in the house. THey use the E30 smart hub and thermostat. Yesterday there was a power outage, and when power came back on one thermostat is blank (no power). Others are fine.
I checked house power, all fuses, and it's all good. I checked the mag mount for the thermostat and it is NOT getting 12vDC. I went to the attic to check the E30 smart hub, it has power (24vAC) through the R and C blocks, but there is NO power being sent to the +/- terminals that go to the mag mount for the thermostat (hence, no power at thermo). The smart hub appears to be on, there is one green light (but the comms lights are all dark). I checked the fuse on the E30 and it's still good.
Is this E30 smart hub fried? Need to be replaced? Any help much appreciated! Thank you!
