22. Power adapter for fixed installation
The CRXSL controller is supplied with a power adapter that
will fit a 35mm or a 25mm metal or dry lining back box. The
power adapter should only be connected to a wiring
protected by a 6A fuse or 6A circuit breaker. Connect line
and neutral conductors to the terminal block. Please note
that the adaptor supplied with the controller must be
installed exactly as the figures show, otherwise the USB
connector will not fit correctly. The centre of the back box
must be kept clear to allow room for the USB connector.
When fitting the wall bracket, ensure that the adaptor is
installed properly and feed the cable through the centre of
the bracket. Screw the bracket to a back box taking care
not to damage the power adaptor or leads with long screws.
Connect the USB cable into the power port at back of the
controller as shown on the photo. Check that the CRXSL is
working. Attach top of the CRXSL to the wall bracket and
slowly tilt it to place observing that the USB connector is
moving in to the opening freely. Once the controller is in
place secure the two screws on the bottom of the controller.
Please note that the controller screen will take up to
one minute to display after powering up for the FIRST
time.
23. Open Window Detection
To ensure you don’t waste energy on heating the outside
world, the heater is equipped with optional open /
closed 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
°
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
°
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).

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.
Please note that if the unit is powered by the power adapter, the
temperature reading REQUIRES recalibration. Lower the value by 1.5
degrees.
02 – change between degrees Celsius or Fahrenheit
03 – set minimum temperature
(- - - = heating OFF, 4deg = frost protection)
04 – set maximum temperature
05 - information about the software version
06 - 0 or 1 manual mode enable / disable
07 - open window detection 0 = off, 1 = on
08 - 600 - open window detection time 600 seconds
09 - 2 - temperature drop of 2°C in the detection time
10 - 30 - closed window detection time of 30 seconds
11 - 2 - temperature rise of 2°C in the detection time
