How to access the menus
Hold the joystick down for more than 5 seconds until the display shows 1rF. Press the joystick gently towards + to browse
through the menus until you reach the one you wish to review or change, then press down on the joystick to select it. The
display will start ashing and you can make your change by pressing gently towards + or –. Finish by pressing the joystick down
once to conrm you choice. You can continue to review other menus by pressing the joystick towards + or –. Exit the menus by
pressing the return button.
Menu 5 – [5 Sen] – selecting sensor(s).
Select both for limiting the temperature in wooden ooring
The choice of wall-mounted or oor sensor is shown by the symbol for oor sensor. If
you choose the oor sensor when no such sensor is connected, you see an error report,
Err. Connect an external sensor, or go to the menus and make another selection.
Menu 1 – [1rF] – link up to the remote control CT
Put the remote control into LINK UP mode. On SF, press in and hold down the joystick
until 1rF is displayed. Press the joystick lightly once and the thermostat shows the zone
number chosen on the remote control. Link-up is now successful.
Menu 2 – [2bP] – selecting the method of control
The display shows bP, alternatively Hys.
bP (proportional band) means that the thermostat switches on and off within a 10 minute
period. With little need for heat, the thermostat will switch off for a longer period and on
for a shorter one. The opposite will apply when it is cold and the need for heating greater.
Together, the on and off periods will always amount to 10 minutes.
Hys (hysteresis) means that the thermostat will switch off when the temperature reaches
0.5°C over the set temperature, and switch on again when it sinks to 0.5°C under the set
temperature.
Menu 3 – [3 0.0 °C] – calibration when the built- in sensor is selected
If there is a large deviation between the set temperature and the actual room temperature,
SF can be calibrated. If the room is too cold, calibrate using + to get a higher value than
0. If too warm, calibrate using – to get a lower value than 0. (Before calibrating, the room
should be stable, i.e. the thermostat should have been in operation for at least 10–12 hours.
Avoid airing the room and opening doors and windows or switching other heat sources on
and off during this period. Under-oor heating is often sluggish to regulate, and it may take
a longer period to acheive stability, often 24 hours or more with cables set in concrete.)
Menu 4 – [4 0.0 °C] calibration when a oor sensor or wall-mounted sensor is selected
If there is a large deviation between the set temperature and the actual room temperature,
SF can be calibrated. If the oor (room) is too cold, calibrate using + to get a higher value
than 0. If too warm, calibrate using – to get a lower value than 0. (Before calibrating, the
room should be stable, i.e. the thermostat should have been in operation for at least 10–12
hours. Avoid airing the room and opening doors and windows or switching other heat
sources on and off during this period. Under-oor heating is often sluggish to regulate, and
it may take a longer period to acheive stability, often 24 hours or more with cables set in
co ncrete.)
