HOW TO OPERATE THE HEATER
DELAY OFF TIMER OPERATION
In addition to temperature controlled operation the heater can also be operated via the use of a delay off timer. This
allows the user to program the heater to operate for a set time period, after which the heater will be returned back
to standby mode.
1. Set the desired operating temperature as per steps 1 through 3 “CONNECTING THE POWER” on page 8.
2. After setting the desired temperature press the MODE button twice. The two digits on the display panel
will now display
0.0 and both the Delay Off Set indicator and the H (time) indicator will begin to flash.
3. Press the ‘Up’ or ‘Down’ buttons to set the required timer operation period.
The delay off timer can be set in 30 minute (
.5) increments up to 9.5 hours and then 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 steady 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 ‘Up’ button for 5 seconds.
6. To stop heater operation completely press POWER button , a shutdown falling chime will be heard and the
power indicator will remain illuminated to show that the heater has returned to standby mode.
If after 5 seconds no buttons are pressed the 0.0 display will revert back to the current operating
setting. Simply press the MODE button twice to re-enter the timer setting operation.
