At the highest setting, an analog thermostat will be set to maintain a temperature between 130 to 140 degrees Fahrenheit.
To preset a specific comfort level between 65F and 85F, adjust the thermostats temperature setting to your desired temperature reading. The Display will show the selected temperature reading. When the preset temperature is reached, the heater will shut off. When the room temperature drops below the preset temperature, the heater will automatically turn on again to maintain the preset temperature level.

To set the heater to maintain a certain temperature: Step 1: Turn the mode knob to the desired heat setting (wattage)
Step 2: Make sure the switch is in the Auto or AccuTemp™ mode and not the Manual mode.
Step 3: Press either the Temp Up or Temp Down button to set the digital thermostat to the desired temperature. The digital readout will flash while the temperature is set. After five seconds, the digital readout will change from showing what the set temperature is (flashing number) to the current temperature around the heater.

The AccuTemp™ feature consists of a digital thermostat that allows you to set your heater to your precise comfort level. It also has a digital readout that will display the current room temperature. If you use the heater in the automatic mode you will be able to set the unit to maintain the desired temperature by individual degrees.
This is an electronic thermostat which is more accurate than an analog thermostat. By simply pressing the single "Mode" button, the heater can be operated in any of its modes. The first press will turn the heater on and it will operate in the last active mode. With each press of the button, the mode will change as indicated by the lit LEDs. The modes include low or high manual (the heater will constantly run) or low and high automatic (the heater will operate to maintain the set temperature displayed by the LED). The set temperatures include 60, 65, 70, 75 or 80 degrees Fahrenheit. The heater is turned off by either holding the button down for two seconds or continually pressing the button until the "Off" mode is reached.
A thermostat is a control that is used to maintain a temperature range in the general area where the heater is located. Most analog thermostats have an estimated range of 37 to 140 degrees Fahrenheit. By adjusting the temperature knob you can set the heater to turn on and turn off automatically as required to maintain the set temperature range.
It takes several minutes for the heater to provide an accurate reading, so allow the heater a few minutes to adjust the temperature display. Also keep in mind that portable electric heaters measure heat directly near the heater - the temperature may vary from the reading on your wall thermostat.
