About the ENERGY SAVE

The air conditioner saves energy costs by controlling the thermostat temperature setting.

*During Heating operation:

The thermostat temperature setting decreases by 2 °F as soon as the ENERGY SAVE button is pressed, and then de- creases by another 2 °F every thirty minutes.

In this manner, energy is saved by continuing to heat at a thermostat temperature of 8 °F below the setting.

During Cooling/Dry operation:

The thermostat temperature setting increases by 2 °F as soon as the ENERGY SAVE button is pressed, and then increases by another 2 °F after one hour has passed.

In this manner, energy is saved by continuing to cool or dry at a thermostat temperature of 4 °F above the setting.
