PC-30 Filter control unit operating manual Page: 11
by the temperature regulation system because this works
in the priority circuit.
Pump blocked The filter pump is switched off temporarily by the
EUROTRONIK-10 or the NR-12-TRS-2 level regulation
system.
Backflushing The filter pump is switched on because backflushing is
taking place using the bar valve.
Rinsing The filter pump is switched on because rinsing is taking
place using the bar valve.
Frost protection
mode
The filter pump is in frost protection operating mode.
Heater operating mode
This line displays the current temperature regulation operating mode.
The following displays are possible:
Controller off Use the key to switch the heater off.
Add. heater off The heater is switched off outside the filter times.
Heater blocked The heater is switched off because the EUROTRONIK forced
switching has occurred.
Temp. reached The heater is switched off because the set temperature has
been reached.
Add. heater on The heater is switched on because the water temperature is
below the set temperature.
Solar heater on The solar heater is switched on because the water temperature
is below the set temperature and the collector is warmer than
the swimming pool water.
Frost hazard The heater is switched on in frost protection operating mode.
Water temperature
The current water temperature is displayed in this line. If the display does not
agree with the actual temperature, it can be readjusted using the adjuster on the
printed circuit board (see temperature regulation section). Turn the adjuster in a
clockwise direction to increase the displayed value. "Sensor break" will be
displayed if the temperature sensor is defective. Caution: If both temperature
sensors are at the same temperature, the solar sensor must never display a
higher value than the water temperature sensor otherwise the solar heater
will not switch off.
Solar temperature
The current collector temperature is displayed in this line. If the display does not
agree with the actual temperature, it can be readjusted using the adjuster on the
printed circuit board (see temperature regulation section). Turn the adjuster in a
clockwise direction to increase the displayed value. "-----" will be displayed if the
temperature sensor is defective. Caution: If both temperature sensors are at
the same temperature, the solar sensor must never display a higher value
than the water temperature sensor otherwise the solar heater will not switch
off.
