Dometic single zone thermostat D1 setting

[Paulywally]

Hi everyone, new to the forum with a 2022 Imagine 23LDE. I have a Dometic single zone thermostat and it was set to a 2 degree temperature differential (D2) on the furnace setting. I changed it to a 1 degree (D1) differential per the manual but am hearing some king of clicking noise coming from the air conditioner of all places, when the furnace runs. The manual says to initialize the thermostat first which I did. Anyone else have this clicking problem and was able to solve it?
I feel that with the 2 degree swing it gets really cold before it comes on and then stays on for a long time until it is too hot in the bedroom. I have the thermostat set to 67 degrees.
Thanks in advance for any help!

We have a GE thermostat and AC and have the same issue with the wide swings. Tried to swap for a wifi thermostat but there are only 3 wires on ours so it wasn't compatible with any that I can find. Anyway, can't help with your issue but can sympathize.

The clicking sounds you are hearing are the gateway relays...
