TIPS ON SAVING ENERGY

Below are some simple ways to save energy when you use your air/air heat pump.

SET THE CORRECT TEMPERATURE•Settingthethermostat1°Chigherthanthedesiredtemperature in the COOL mode and 2°C lowerin the HEAT mode will save approximately 10percentinpowerconsumption.

•Setting the temperature lower than necessaryduring cooling operation will result in increasedpowerconsumption.

BLOCK DIRECT SUNLIGHT AND PREVENT DRAFTS•Blocking direct sunlight during cooling operationwillreducepowerconsumption.

•Close thewindowsanddoorsduringcoolingandheatingoperations.
