The sensor fault, understood as a short circuit or open circuit, 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 detect fl ow rate in the solar circuit
for 10 consecutive minutes.
The fault causes deactivation of the Solar Pump. After checking and eliminating the fault, the protection can be
removed, activating and deactivating the Off mode.
Make sure parameter P25 is correctly set.
Sensor characteristics
The temperature sensors can be checked with a digital multimeter: disconnect the sensor from regulator and
check correspondence with the following tables.
