When the ideal temperature is high, the thermostat won’t activate the aux function even when the temperature drops to 40 degrees or even lower.
3. Increase the Surrounding Temperature
The easiest thing you can do is probably increase the temperature inside the house or the temperature around the thermostat. There are a few things that you can do, including:
a. Use the Sun Energy
Take advantage of the sun’s energy. After all, they are free. During the day or when the sun is shining bright, open the grilles, doors, and windows to let the heat comes inside the house.
b. Install Insulation
Installing insulation can be a good idea here. Insulation prevents heat from escaping the space, thus helping the temperature inside the house to remain balanced.
c. Use Firewood/Fireplace
When an indoor fireplace or firewood completes your house, turn the fire on and increase the house’s temperature by doing so.
Those are some of the things you can do to make sure that the “aux” feature won’t get activated. If your surroundings’ temperature is shallow, though, just let the thermostat do its job and turn this feature on.
