* The water sensor is optional: if it is connected, the board will allow operation of the fan only with water tem -
perature 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.
** When the use of the water probe is envisaged, it is NECESSARY to select Winter/Summer mode by means
of the contact E/I.
Open = Winter Closed = Summer
*** 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.
If the E/I contact is not available, disconnect the H

O probe.
