Furnace maintenance and understanding its controls is important for operating it safely.

Depending on your particular furnace you’ll find:

• When you switch up the position, it will run the fan on low
• It is recommended to use the ‘on’ position during cooling months
• The button down below is pretty straightforward; it turns off cool and heating

To change the battery:

• Remove the thermostat from the wall and you will see there are two AA batteries* inside.
• Take the old batteries out, and make sure the polarity is correct on the new ones
