The controller also ensures anti freezing when in stand-by.
Key Operation Display
Press and hold the ON Stand-By key for approx. 2 seconds. No illuminated signals on
the display at all means that the system is in stand-by (no operation).
From on to off
Key Operation Display
The fan speed is selected by using one of the 4 keys (automatic, minimum, super silent
and maximum). The activation of the function is indicated by
the relevant symbol on the display.
In automatic mode, the fan carries out a "stepped"
adjustment to move the room temperature closer to the
set point.
The super silent setting activates powerful dehumidifying
when cooling and only radiation (with the fan off, solenoid
valve, and in the RS version, microfans activated) when
heating. By setting the highest speed, the maximum possible
power level is activated immediately whether heating or
cooling.
Once the desired room temperature is reached, we
recommend selecting one of the other 3 operation modes
for increased comfort and sound levels.
In "minimum" mode, the number of fan revolutions is
limited both when heating and cooling.
Key Operation Display
By pressing both the + and - keys for 3 seconds, all keys are locked locally, and this is
indicated by "bL" appearing on the display.
All actions are disabled to the user and whenever any key is pressed, "LOC" will appear.
To unlock the keys, repeat the sequence.
Key lock
Reduce brightness to minimum
After 20 seconds from the last action, the panel brightness
will be reduced for improved night-time comfort, and the
room temperature will appear on the display.
If this brightness is still disturbing, the display can be switched off completely.
Key Operation Display
With the display off, press and hold the + key for 5 seconds until "01" is displayed.
Use the - key to change the value to 00 and wait 20 seconds to check the setting has
been accepted.
