To connect a safety flow switch for the solar thermal/hot water
recirculation circuit to the equipment, proceed as follows (re-
served only for qualified technical personnel):
• Disconnect the power to the equipment.
• Remove the top cover of the equipment and then the power
board cover.
• Disconnect the “jumper” (bridge 1) from connector CN7 of the
power board, then cut the conductor forming the bridge in the
middle and connect a suitable terminal.
• Then connect a normally-closed (N.C.) type flow switch and
connect everything to CN7.
• Reassemble all the plastics and make sure the equipment is
correctly installed before powering it.
If, instead, a normally-open (N.O.) type flow switch is used, it is
necessary to set the parameter
P15 = 1
(see par.8.1).
To connect the thermal cut-off (supplied) for the solar circulation
pump, proceed as follows (reserved only for qualified technical
personnel):
• Disconnect the power to the appliance;
•
Put the bulb fully inside the dedicated tank pit (“A”) and close
the cable gland;
• Unwind the capillary enough is necessary to place the ther-
mal cut-out inside an adequate enclosure fixed to the wall;
• Connect the thermal cut-out in series with line (“L”) and neu-
tral (“N”) power-supply connections of solar circulating pump,
for all-pole disconnection.
• Verify all connections before power-supply the appliance.
