Controls:
- Thermostat Dial (MIN to MAX): This dial controls the desired room temperature. Turn clockwise to increase the temperature setting and counter-clockwise to decrease it. The heater will cycle on and off to maintain the set temperature.
- Power Switches: The heater typically has multiple power switches to select different heating levels (e.g., low, medium, high) or to activate the PTC fan heater independently. Refer to the markings on your specific unit for exact functions.
- PTC Fan Heater Switch: Activates the fan heater for quicker heat distribution.
Operating Instructions:
- Power On: Plug the heater into a grounded electrical outlet.
- Select Heating Level: Use the power switches to select the desired wattage or heating mode. For initial rapid heating, you may select the highest setting and activate the PTC fan heater.
- Set Thermostat: Turn the thermostat dial to the 'MAX' position to begin heating. Once the room reaches a comfortable temperature, slowly turn the dial counter-clockwise until the heater turns off. The heater will now maintain this temperature.
- Fan Heater Use: Activate the PTC fan heater switch for additional warmth and faster heat circulation.
- Power Off: To turn off the heater, switch off all power switches and unplug the unit from the wall outlet.
