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 sufficient 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 82 - Regulator configuration fault

Make sure parameter P26 is set to “0”.

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 shutter closing . 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 flashing .

Fault 84 - Solar Collector Return NTC Sensor S4 faulty

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 flashing .

Fault 85 - Boiler card communication fault

Make sure parameter P26 is set to “0”.

Fault 87 - Protection for no circulation

Only with

FLOWMETER ENABLED

This fault is activated when, with the Solar Pump activated, the card does not detect flow in the solar circuit for 10 con-
secutive minutes . The fault causes deactivation of the Solar Pump. After checking and eliminating the fault, the protec-
tion can be removed, activating and deactivating the Off mode .

Make sure parameter P25 is correctly set.
