HOW TO OPERATE THE HEATER
DELAY OFF TIMER OPERATION
In addition to MANUAL OPERATION the heater can also be operated using a delay off timer. This allows the user
to program the heater to operate for a set time period.
1. Set the desired operating temperature as per steps 1 through 3 “MANUAL OPERATION” on page 8.
2. After setting the desired temperature press the MODE button twice. The two digits on the display panel
will now display
00.
3. Press the ‘Up’ or ‘Down’ buttons to set the required timer operation period. The delayed off timer can be
set in 1 hour increments to a maximum of 24 hours.
4. To exit the delay off timer setting operation either press the MODE button once or wait 5 seconds.
The Delay Off Timer Set indicator will illuminate green to indicate that the heater is now in delay off timer
operation.
If the selected temperature is above that of the current room temperature the red operation indicator will
illuminate and the heater will begin to heat the room.
If the selected temperature is less than that of the current room temperature the red operation indicator will
go out and the heater will go into a standby state until the room temperature has fallen below the set
temperature, when the heater will then automatically switch on and heat the room.
The two digits on the display panel will alternate every 5 seconds between displaying the set temperature
and the time remaining of the set delayed off timer period.
5. To cancel delay off timer and return manual operation press MODE button three times.
6. To stop heater operation completely press power button .
If after 5 seconds no buttons are pressed the 00 display will revert back to the current operating
setting. Simply press the MODE button twice to re-enter the timer setting operation.
