heater on and off. To turn on ,

spark generator will be heard
before the burner ignites and
the indicator will then glow red.
When the heater warms up the
fan will automatically start.
To turn the heater off, press the
ON/OFF button, the indicator
light will go out. The fan will
continue to operate to cool the
appliance and then stop.
Set times

temperatures (1005FT model

programming.
Temp and time
Increases or decreases the
temperature as well as changing
the hours or minutes when in
programming mode.

except OFF. Hold for two
seconds to deactivate. If the
child lock is pressed while the
heater is off all functions will be
locked, including turning the
heater on, until it is deactivated.
Filter
Indicates the filter needs
cleaning. If you do not clean
the filter at regular intervals and
the filter indicator is allowed to
remain flashing, the appliance
will stop and the display will
show error code 14. The filter
will need cleaning before the
appliance can be turned back
on (refer p. 11).
Clock and timer indicators
When programming, the
indicators will glow to indicate
what is being programmed.
The 1005FT model also has a
'Temp' indicator that indicates
the set temperature for the
timer that is being set.
Display window
Shows either the time of day,
temperatures or coded error
message.
Adjusting the room
temperature
Pressing the up and down
arrows will change the preset
temperature by 1 °C. The
temperature will be shown in
the display window. The room
temperature sensor is located
behind the Energysaver so the
temperature on the display may
vary slightly from the actual
room temperature.
The temperature can be preset
to:
• L (low)
Unit operates on the lowest
burner setting.
• 16-26 °C
Unit will modulate, and in
some instances turn off and
on, to maintain the selected
temperature.
• H (high)
Unit operates on the
highest burner setting.
The 'L' and 'H' settings are not
normally used as it means the
heater operates without a set
temperature.
Economy
Prevents the room overheating,
reduces gas consumption, and
ultimately saves energy. Once
the room has reached the
desired temperature, the unit
automatically begins gradually
reducing the set temperature
(set temperature on digital
display will stay the same).
This reduction is normally not
noticeable.
How it works
After the room reaches the
set temperature, the set
temperature will automatically
start decreasing, dropping
by a maximum of 1 °C in 30
minute blocks, until comfort
control is reached. When in
comfort control the unit alters
combustion and fan speed to
keep the room at a comfortable
temperature.
