ETR Operation
Operating the Timers
Before operating the 'Timer(s)', the clock time must be correct and a start and finish time
must be programmed (see previous page). This heater does not commence operation at
the programmed start time, as it attempts to heat the room by the programmed start time
(refer Preheat section below).
To select the 'Timer(s)' to commence heating:
1. Check the time shown on the digital display is correct
2. Check the 'ON' and 'OFF' times for both timers if necessary
3. Press the 'ON/OFF' button to operate the heater, the 'ON' indicator will glow green and
the heater will begin to operate
4. Select the desired temperature setting
5. Press the 'Timer 1' and/or 'Timer 2' button(s). The timer indicators will glow and the
heater will remain in standby until one hour prior to the time programmed. When this
time is reached, the 'Timer' indicator will flash and the heater will operate. The 'ON'
indicator glows red when the heater commences operation.
Set and Forget Operation
The heater can be operated to alternate between timers automatically during cold weather
by selecting 'Timer 1' and 'Timer 2' together. Both timer indicators will glow. The appliance
will remain on standby at intervals between the programmed start and finish times of each
timer. While the heater is operating during programmed intervals the timer indicator will
flash.
What does all this mean...
you can program the heater to turn on in the morning when you wake up and turn off when
you leave and also again in the evening when you get home. The set and forget operation
combined with the preheat functionality means you can wake up and come home to warm
areas in the house.
If there is a power failure, the system memory will retain the timer programs, and the clock will stop at the
time the power goes off. The clock will start again when the power comes back on, but the time will be slow by
the duration of the power failure. To set the clock to the correct time after the power has come back on, follow
the instructions on previous page.
Preheat
This function operates automatically in conjunction with either of the timers. When a timer
is selected, the heater may turn on anywhere within an hour prior to the programmed
start time of the timer. The preheat function will attempt to preheat the room by the
programmed 'ON' time.
This function is called the preheat due to the way it operates. The room temperature is
sensed one hour before the programmed time of either timer. The temperature differential
at the time of sensing the room governs how long before the programmed 'ON' time the
mircocomputer will operate the heater and ignite the burner.
