1. Turn the Thermostat Control clockwise to the highest position to start heater. Allow heater to operate and warm up the room.
  2. When the desired temperature/comfort level is reached, lower the temperature setting by turning the Thermostat Control counter-clockwise until the heater stops operating.
  3. This will now be the unit's pre-set temperature level and the thermostat will now automatically maintain that temperature range by turning the heater ON and/or OFF accordingly.
