Make sure the regulator is powered: using a digital multimeter, check the presence of voltage at terminals 24
and 25.
In case of no voltage, check the wiring.
In case of suffi cient voltage (Range 195 – 253 Vac), check the fuse. The fuse is located inside the regulator: to
access it, follow steps 1 and 2 of the section on Regulator Installation

Fault 81 - Upper Hot Water Tank PT1000 Sensor S1 faulty
Only with SYSTEM 2 and SYSTEM 3
The sensor fault, understood as a short circuit or open circuit, causes deactivation of the output Relay connected
to terminals 13-14-15 (FREE CONTACT on the 11-pin connector). On eliminating the fault, the protection is
immediately deactivated.
To signal this fault, the symbol S1 will be deactivated, whereas the Fault symbol, the symbol S1 and the backlight
will start fl ashing.
Fault 82 - Hot Water Tank NTC Sensor S2 faulty
The sensor fault, understood as a short circuit or open circuit, causes deactivation of the Solar Circulating Pump
and closing of the shutter. On eliminating the fault, the protection is immediately deactivated.
To signal this fault, the symbol S2 will be deactivated, whereas the Fault symbol, the symbol S2 and the backlight
will start fl ashing.
Fault 83 - Solar Collector PT1000 Sensor S3 faulty
The sensor fault, understood as a short circuit or open circuit, causes deactivation of the Solar Circulating Pump
and closing of the shutter. On eliminating the fault, the protection is immediately deactivated.
To signal this fault, the symbol S3 will be deactivated, whereas the Fault symbol, the symbol S3 and the backlight
will start fl ashing.
Fault 84 - Solar Collector Return NTC Sensor S4 faulty
Only with SYSTEM 1
The sensor fault, understood as a short circuit or open circuit, does not cause deactivation of the Solar Circu-
lating Pump. The system must simply work as though the Basic System were set. On eliminating the fault, the
protection is immediately deactivated.
To signal this fault, the symbol S4 will be deactivated, whereas the Fault symbol, the symbol S4 and the backlight
will start fl ashing.
Only with SYSTEM 3
