•
If the terminal “PV switch” is closed and TS1 manually adjusted (by display button) <
“TS1 calc”, the controller will automatically switch to “TS1 calc”.
•
If the terminal “PV switch” is closed and TS1 manually adjusted (by display button) >
“TS1 calc”, the controller will automatically switch to TS1 manually adjusted
•
When the terminal “PV switch” is opened (there is no solar voltaic energy), the appli-
ance will work in normal “heating mode”.

11.3. Installation of an external re-circulation pump and flow switch
In case there is the possibility to re-circulate solar water or hot sanitary water, an external
pump and flow switch must be connected and installed hydraulically and electrically. If
the flow switch is not present, short connect contact FS 17. The max available output
for the pump is 5 A resistive. Also, the optional thermosensor 18 must be connected to
the controller and correctly positioned on the hydraulic plant. Parameter No. 14 must be
configured by the installer (1= hot sanitary water circulation).
The circulation of hot sanitary water is useful to avoid water that becomes cold in the
sanitary circuit if not used for a while. In this way the hot water will be always ready when
requested.
The logic of recirculation pump function is as follows:
The pump will start when the below conditions are satisfied at the same time:
•
The unit is on
•
T3 (upper tank water temperature)
≥
parameter 15 + parameter 16
•
T6 (temperature of circulation water - thermosensor 18 )
≤
parameter 15-55ºC
The pump will stop when one of the below conditions is satisfied:
