* the water sensor is optional: if connected, the board will allow operation of the fan only with water temperature suitable
for the selected mode of operation (higher than 30°C in winter mode and lower than 20°C in summer mode). If it is not
connected, the board shall not carry out any check of water temperature.
** The fan operation is enabled only when the EV input is closed. Follow the connection diagram to the EV input even if
the valve management is not required. When the EV input is closed, only output Y1 is energised.
