I recently replaced my Living Room thermostat with a MicroAir.
Dometic had sent me a free replacement for my OEM living Room thermostat in 2019. The OEM Dometic thermostat in the bedroom started acting up in the last few months. I relocated the newer Dometic to the bedroom. The pic below is of my bedroom thermostat wires...gray-green-blue.

If you look at the number "18" just above the screen - I think that is a date of manufacture. The OEM bedroom thermostat I replaced had "16" on it.
