The thermostat is in control of one of the most important systems within the home: the HVAC system. This system dictates your comfort level and allows you to choose the temperature that you find most comfortable. However, there is a setting on the thermostat that can disrupt this comfort if it is not set appropriately. The temperature differential can give the thermostat a few degrees leeway before turning your HVAC system on or off. This could allow your homes temperature to fluctuate drastically all while the thermostat continues to read the original set temperature.
Resetting the Differential
Let’s say that you are most comfortable at 70 degrees during the winter season. You set the thermostat and go about your day. Every time the furnace comes on the house gets to feel uncomfortably warm. In between cycles when the furnace is off, the home becomes uncomfortably cold. The temperature differential is probably set at three degrees. That means that the temperature can get as warm as 73 degrees and as cold as 67 degrees before the thermostat responds to the temperature. This is what is causing your discomfort. Check with your thermostat manual for instructions to change the differential and set it back to one degree. This will give you the temperature you desire and eliminate this source of discomfort.
