SET AND FORGET OPERATION

Your heater can be operated to alternate between Timers automatically during cold weather by selecting both Timer
1 and 2 together. The Timer indicator(s)
intervals between the programmed finishing and starting times of each Timer. While the heater is operating during
programmed intervals the active Timer indicator
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 re-start again when the power comes back on,
but the time will be slow by the duration of the power failure.
NOTE
To set the clock to the correct time after the power has come back on, simply follow the
instructions on "Setting the Clock" on page 12.

PRE-HEAT

This function operates automatically in conjunction with the
Timers. When a Timer is selected, the heater may operate
anywhere within an hour prior to the programmed starting
time on the Timer. This function is called Pre-Heat since it
ensures the room reaches the desired temperature by the
programmed starting time.
The room temperature is sensed one hour before reaching
the Timers programmed ON time. The temperature
differential at the time of sensing the room temperature
combined with the data from previous operation governs
exactly how long before the programmed 'ON' time the micro-
computer will operate the heater and ignite the burner.

OVERRIDE

This function is intended to be used to manually override the current operation of the heater. For example; if the
heater is in standby mode (i.e. between finishing time and starting time of a Timer) and the Override
selected, then the heater will begin to operate and heat the room.
To operate the Override simply press the Override button
To manually deactivate the Override simply press the Override button
out, and the heater will return to standby 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 appliance. This means that the
Override mode will automatically drop out if a programmed starting time is reached.
The appliance will then return to operating at the times programmed into the Timer(s).
