Hi, I have a RiteTemp 6036 thermostat installed in my house. It's a single-zone heating / cooling system. Recently, I've noticed that the thermostat will get the house temperature to it's target but it won't turn-off the AC.
For example, the thermostat is set to cool to 74 and the current temp will be 74 or, more often, 73.5, but the thermostat won't turn off the AC.
If I manually turn-off the thermostat and then turn it back on, it won't kick the AC back on until the temp rises above the target temp. If I don't manually turn-off the thermostat, i've seen it end up running the AC for an extra 20 or 30 minutes. Any thoughts on why it's struggling to turn-off automatically?
I'm assuming this is a thermostat issue, not an AC issue. Could this be faulty setup, or a faulty device? Any thoughts would be appreciated. Thanks...
