Thermostats are normally found on the inside wall of a house, most commonly in the hallway. Follow these simple steps to check if your thermostat is correctly set.

1.Check the dial or display on your thermostat to see what temperature it is set to

2.To change the temperature, turn the dial or program the display to your preferred temperature

3.You may hear a click when you turn the dial to the current room temperature
