LOCK AND OTHER SAFETY DEVICES
USING THE OVERRIDE FUNCTION
This function is used to manually override the current
timer controlled operation of the heater.
For example:
If the heater is between the finishing and starting times of a timer program and the Override button is
pressed the OVERRIDE indicator will illuminate (if the digital display is blank press the
Override button twice) and the heater will begin to operate and heat the room until the next timer
off operation is reached.
If the heater is between the starting and finishing times of a timer program and the Override button is
pressed the OVERRIDE indicator will illuminate and the heater will stop heating the room until
the next timer on operation is reached.
To cancel override and to return to Timer operation press the Override button again. The Override
indicator will go out.
USING THE LOCK FUNCTION
The Lock function avoids accidental operation and
prevents small children from altering settings.
To Activate the Lock
To activate the Lock function press both the Up and Down buttons simultaneously for 3 seconds.
The function is activated immediately and the Lock indicator will be illuminated.
To Deactivate the Lock
To deactivate the Lock function press both the Up and Down buttons simultaneously for 3 seconds.
The Lock indicator will go out to show that the Lock function is no longer active. The Lock function
can be deactivated at any time in this manner.
SAFETY DEVICES
Overheat switches
If various critical components of the heater get too hot during operation these devices turn the gas off
automatically.
Electrical fuse
The electrical circuits are protected by a fuse.
Flame failure sensor
This device automatically cuts off the gas supply to the heater in the event of a gas failure.
Power failure
In the event of a power failure or power cut, the gas valves will automatically close.
If the STANDBY/ON button is pressed the heater will be turned off and the timer
programs will not operate.
If the Lock function is activated whilst the heater is in operation or in Timer mode, all
controls other than the ability to switch the appliance OFF with the STANDBY/ON
button will be locked until the Lock is deactivated. Timer operation will not be
affected.
If the lock function is activated whilst the appliance is in the off position, all controls
will be locked until the Lock function is de-activated.
If the appliance is switched off whilst the Lock function is activated, all controls will
be locked until the Lock function is de-activated.
Lock programming (activated or de-activated) is stored in the appliance memory.
Unplugging the appliance from the power supply has no effect on Lock programming.
