ECONOMY MODE

The economy mode, when selected, has the ability prevent discomfort from over heating and to reduce gas
consumption and ultimately save energy. Once a room has reached the desired temperature, the unit will
automatically begin reducing the set temperature gradually. This reduction is normally not noticeable, however, it
is purely your choice whether to select this mode.
Room temperature may not decrease in some cases, this is depending on room style, location of
the appliance and the temperature outside the room.
NOTE
The economy mode can only be operated when the heater is turned 'ON', but remains in the
system memory until deactivated.
The economy mode will not operate when the set room temperature is less than 16°C or is above
26°C.
How it works :
After a room reaches the set temperature, the set room
temperature will decrease 2 times automatically, each
time, dropping by a maximum of 1°C in 30 minute
blocks. From the second cycle onwards, the comfort
control will automatically operate. (The comfort control
alters combustion and fan speed more frequently to
counteract the feeling of cold air).
1. Press the Economy button
2. Press the Economy button
When the Economy function is operating, the current room temperature may be shown as being
lower than the set room temperature, however, this is normal.
NOTE

During normal operation the Child / Function Lock may be activated and all controls, other than the 'OFF' switch,
will be locked. Deactivating the Child / Function Lock releases the controls. If the Child / Function Lock is activated
whilst the heater is turned 'OFF', then all functions will be locked. If the heater is turned 'OFF' while the Child /
Function Lock is activated, it cannot be turned 'ON' again until the Child / Function Lock is deactivated.

FAN OPERATION

The fan turns 'ON' automatically when the heat exchanger warms up and turns "OFF" when it cools down. This
helps to prevent cold draughts and maximises efficiency.
