Display
Communication error: The board is provided with a function that allows continuous information
exchange on the serial line with the wall-mounted control panel. If it is missing for more than 5
minutes the error is displayed and the device is deactivated.
6 f pause
Fan motor fault (for example jamming due to foreign bodies or fault in the rotation sensor).
2 f pause
Water temperature probe failure.
In this case make sure the probe has 10 kΩ.
3 f pause
Water temperature outside operating range (over 20 °C in cooling, below 30 °C in heating). The fan
will stop until the temperature reaches an appropriate value to meet the request*.
1 flash + pause
* If after powering the equipment the board detects the
water probe, the start-up will take place with minimum and
maximum water temperature thresholds.
The board can also operate without a probe, case in
which the fan stop thresholds will be ignored.
