Installation

How do I verify the power is off?

On your existing thermostat, set the fan option to “ON”, then hold your hand over a vent. You should not feel air blowing from the vent. If you’re unsure if air is blowing, you can simply place a piece of paper over the vent register and see if the paper blows around.

In either case, if air is blowing from the vent, the equipment was not turned off properly. Please verify that the furnace switch is in the off position or that the correct breaker was switch off before proceeding.
