8. FAULTS

LCD display off

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 "Accessing internal terminal blocks".

LCD display on

Any operation error conditions are shown on the regulator LCD display.
Fault code Description
Card Fault
F81 Upper Hot Water Tank PT1000 Sensor S1
F82 Hot Water Tank NTC Sensor S2
F83 Solar Collector PT1000 Sensor S3
F84 Solar Collector Return NTC Sensor S4
F85 Regulator confi guration fault
F87 Protection for no circulation
Fault 81 - Upper Hot Water Tank PT1000 Sensor S1 faulty
Only with SYSTEM 2 and SYSTEM 3
The fault, understood as a short circuit or open circuit, of the Sensor 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 fault, understood as a short circuit or open circuit, of the Sensor 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 fault, understood as a short circuit or open circuit, of the Sensor 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 fault, understood as a short circuit or open circuit, of the Sensor does
not cause deactivation of the Solar Circulating 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
The fault, understood as a short circuit or open circuit, of the Sensor does
not cause deactivation of the Solar Circulating Pump. The system must
simply work as though the System 2 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.
Fault 85 - Regulator confi guration fault
Make sure parameter P26 is set to 1.
Fault 87 - Protection for no circulation
Only with FLOWMETER ENABLED
This fault is activated when, with the Solar Pump activated, the card does not
Multifunction Solar Column
detect fl ow rate in the solar circuit for 10 consecutive minutes.
The fault causes deactivation of the Solar Pump. After checking and elimina-
ting the fault, the protection can be removed, activating and deactivating the
Off mode.
Make sure parameter P25 is correctly set.

9. SERVICE MENU

The regulator Service Menu is accessed by pressing the Info button for 10
seconds. Press the Up/Down buttons to select "tS", "In", "Hi" or "rE". "tS"
means Transparent Parameters Menu, "In" Information Menu, "Hi" History
Menu, and "rE" History Menu Reset. After selecting the Menu, press the
Info button to access it.
"tS" - Transparent Parameters Menu
The regulator has 26 editable transparent parameters:
