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 9. 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-bys 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 9.

•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.
