I have the Comfortzone Infrared heater. The heating unit will not kick on. It tries to but then a code comes up that looks like AOS or AO5.


sounds like the outlet is not enough power for the heater. Remember with an electric heater youre dealing with watts and amps, It should be plugged into its own dedicated service for proper operating.

Honeywell HZ-705.....HELP!!!!


Should have oil in it. I don't think you can refill it. If it has leaked out, it's probably no good. Anyway, here are the instructions.


Press the *power button* once to start the heater on high power, continuous run. If left at this setting, the unit will run continuously on high power (1500 watts, 12.5 amps) and will not shut off until the unit is manually turned off.
Press the *power button* again, to change to low power, continuous run, (900 watts, 7.5 amps) and will not shut off until the unit is manually turned off.

Set temperature:

Press the temp/timer button until the temperature icon blinks. Use the up and down arrows to set the desired temperature.
The temperature icon will stop blinking and the current room temperature will reappear after the desired temperature is set.

The heater will turn off and on to achieve the desired temperature.

Set timer: (auto off)

Press the timer/timer button until the timer icon blinks. The hour display will appear. The auto off icon will also appear.
Use the up and down arrow buttons to set the heater operation time between 1 and 10 hours. This function will activate once the timer icon stops blinking. The heater will automatically turn off whn the times runs out.

Set timer: (auto on)

Press the temp/timer button until the timer icon blinks. The hour display will appear. The auto on icon will also appear.
Use the up and down arrow buttons to set the heater start time between 1 and 10 hours. This function will activate once the timer icon stops blinking.
The heater will automatically turn on when time expires.

Hope this helps!
