My energy bills are too high. Is there anything I can do?
While we can’t do anything about the high cost of energy, we can try to use less energy thereby lowering our heating and
cooling costs.
Generally, the best way to do this is to use the EPA E

recommended setpoints for heating and cooling.

Another way to contain costs is to cycle the heat pump or air conditioner with moderation. The thermostat controls the cycle rate
based on temperature differentials. By maintaining a reasonable differential setpoint, 1°F for 1st stage and 2°F for 2nd stage,
your furnace will cycle with moderation.
Finally, using the remote outdoor sensor coupled with the balance point feature (see INSTALLER SETTINGS, page 21) will
allow your furnace to cycle to the most efficient stage for your heating or cooling needs.
