Hi,
I have 3 pieces of Honeywell CM907 thermostat in the house for my years. The one in the bathroom is the oldest one.
This one does not hold time. Whenever I set time again to the correct time, it starts to run behind over time. It does so slowely, meaning it now runs behind over an hour while I reset it some years ago.
Anyone an idea if this is just one with a faulty board or can this be fixed?
