Accutemp Digital Thermostat, Cleaning/Maintenance

ACCUTEMP™ DIGITAL THERMOSTAT

Your heater is equipped with an AccuTemp™ Digital Thermostat that allows you to set your heater to your precise comfort level.

Setting the AccuTemp™ thermostat:

1.Make sure the Manual/AccuTemp™ switch is set to AccuTemp™. The LCD display will read 75°.

2.Turn the mode control to LO(Low) or HI(High).

3.Push the temperature set button until the display reads your desired temperature.

To increase the temperature push the top button, for lower tempera- tures push the lower button. When finished setting the temperature, release the button and the display will flash to indicate the thermo- stat will be set to that temperature.

4.The display will return to existing room temperature and gradually increase until the room has reached your pre-set temperature.

5.If the unit will not start in the AccuTemp™ mode, please make sure the “set temperature” is higher than the current room temperature.

NOTE: It is normal for the heater to cycle ON and OFF as it maintains the preset temperature. To prevent the unit from cycling, you need to raise the thermostat setting. When the preset temperature is made, the fan will run for 30 seconds without heat. This cool down process ensures an accurate and consistent temperature reading. If you unplug the heater, you will have to reset the AccuTemp™ thermostat again by following the above instructions.

Manual Operation:

1.If you want the heater to run continuously, turn the Manual/AccuTemp™ switch to Manual and adjust the mode control to LO(Low) or HI(High).

SETTING THE THERMOSTAT

1.You need to set thermostat on HI(High) to start heater (See fig.#1 and #2). Allow heater to operate and warm up the room.

2.When the desired temperature/comfort level is reached, lower the thermostat setting until the fan/heater stops operating.

3.The control will now automatically maintain the pre-set temperature level by turning the heater ON and OFF.

Note: It is normal for the heater to cycle ON and OFF as it maintains the preset temperature. To prevent the unit from cycling, you need to raise the thermostat setting.
