I'd suggest you just set the temperature knob to where you're comfortable, regardless of what the temperature readings are ......
Reminds me of a back-in-the-day story. This small church that my family attended had a thermostat on the wall in the back of the church.
People kept turning it up or down. One day I ask the custodian that if he wasn't worried about the constant turning the furnace on of off being bad for the furnace.
He chuckled and said "no, not really, that thermostat in the back of the church is a dummy ....... it's not hooked up to anything".
THE END
