proceed to TIMER 2 - which is
programmed in the same way - or three
times to return to the clock display. This
must be done within 1 minute of setting the
time to lock it into the memory.
The digital display will show the current
time. A small indicator on the digital display
will flash to show that the display has
returned to the clock.
After setting timer 2 the SET TIMES button
must be pressed once within one minute
of programming to lock in the times and
return to the clock display.
The timers operate over a 24 hour period,
and will activate 7 days a week when set.
• OPERATING THE TIMERS
Before operating the timer(s), the clock
time must be correct and a starting time
and finishing time for the timer(s) must be
programmed,
see page 10. Both timers
operate in the same way.
Ignite the heater and select the preset
temperature as for normal operation.
Press the timer 1 and / or timer 2 button(s).
The timer indicator(s) will glow and the unit
will change to stand-by mode. The burners
will extinguish and the ON indicator will
change from red to green. The display will
show the start time for the selected timer
briefly before returning to the clock display.
When the heater is in stand-by mode, you
can display and change the clock and the
on and off times for both timers in the same
way as described earlier.
The timers can be deactivated by either
pressing the timer button(s) that you want
to deactivate or by turning the heater off
using the ON/OFF button.
NOTE: 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, simply follow the instructions on
page 10.
• OVERRIDE
This function is intended to be used to
manually override the current operation of
the heater. For example; If the heater is in
stand-by mode (ie. between finishing time
and starting time of a timer), and the
OVERRIDE button is selected, then the
heater will begin to operate and heat the
room.
Press the OVERRIDE button to activate.
The indicator light will flash when active.
To manually deactivate the OVERRIDE
press the OVERRIDE button again. The
OVERRIDE indicator will go out, and the
heater will return to stand-by mode.
The heater will continue to operate on
OVERRIDE until the OVERRIDE button is
pressed again, or one of the timers takes
over the operation of the heater. This
means that the OVERRIDE mode will
automatically turn off if a programmed
starting time is reached. The heater will
then return to operating at times
programmed into the timer(s). Turning the
heater off will also deactivate the
OVERRIDE.
• REMOTE CONTROL
The remote control can only be used for
manual operation of the heater. If the
heater is in stand-by (timer) mode then only
the OFF button will work. Pressing the OFF
button when the heater is in stand-by mode
will deactivate the timers and the heater
can now be operated manually.
The ON and OFF buttons on the remote
work in the same way as the ON / OFF
button on the control panel as do the “
“ and “
“ buttons.
