13. Open Window Detection
Ensuring you don’t waste energy on heating the outside world,
the heater is equipped with optional open / aclosed window
detection. The heater recognises sudden drops in temperature
when a window or a door is opened and turns the heating
off to save energy. When the window is closed, the heater
will automatically detect a temperature rise, and switch itself
back on. Once enabled in the setup menu, the open window
detection is fully automatic and does not require any human
intervention to be activated.
Setting-up Open Window Detection
The system has been factory set to default time and
temperature values. If necessary, all values can be adjusted.
When the heating is on, open window detection sensor will
automatically switch the heater off when it detects a fall in
temperature of 2
o
C in less than 10 minutes (this temperature
can be changed in menu 7 and time in menu 6). If a
temperature rise of 2
o
C
in less than 30 seconds is detected,
the heater will switch itself back on (this temperature can be
changed in menu 9 and time in menu 8).
14. Setup Menu
1. Press and hold TEMP and MODE together for 5 seconds.
2. The display will enter the setup menu.
3. Use TEMP and MODE to change a value.
4. Use TIME to scroll between the settings.
01 - Temperature calibration
The temperature reading has been factory calibrated but if
for any reason it needs adjusting (better accuracy required,
to suit different position in the room etc.), the reading can be
recalibrated in 0.5 degrees steps.
02 - Change between degrees Celsius or Fahrenheit
03 - Set minimum temperature
(3.5 deg = frost protection) When this is set, the heater will
operate in any mode should the room temperature fall below
the set temperature.
04 - set maximum temperature
When this is set, the maximum temperature in any mode
cannot exceed the limit.
05 - open window detection 0 = off, 1 = on
06 - 600 - open window detection time 600 seconds
07 - 2 - temperature drop of 2
o
C in the detection time
08 - 30 - closed window detection time of 30 seconds
09 - 2 -
o
temperature rise of 2
o
C in the detection time
