the hot water coil. The  hot water coil connections are 3/8” diameter for models 75-100 and ¾’’ for models 150-200.
The modulating 3 way valve is installed directly in factory as showed in the picturet. It is controlled directly by the board.

This option is available only in combination with the electronic probe RGDD. It is not available in combination with 
remote mechanical hygrostat.

the fan, in any case never less than 35 mm.

The inlet maximum water temperature allowed is  80°C. 
The inlet minimum water temperature allowed is 55°C. 

For a correct functioning of the unit, it’s advisable to bleed carefully the circuit using the vent valve present in the unit.

For proper equipment operation, it is recommended powering the unit with a dedicated pump. It is strongly recom-
mended to connect the unit upstream  of the collector system to ensure proper water supply (see drawing).
