In order to ensure the safest possible and failure-free operation, the regulator is equipped with a variety of protective elements. In
the event of malfunction you will hear a warning sound (ALARM – if not silenced) and the display will show the applicable error
information. Alarm sound could be silenced from menu.
CH guage damaged
If this condition occurs, please call technician for service or part replacement.
CH Temperature too high
If this condition occurs, allow more heat to be conducted away from the boiler. Alarm
temperature is above 95 ºC.
Ignition not succeeded
Please check fuel bin condition and operation of fan.
After the cause of such alarm has been remedied and the regulator reset, the boiler will operate in its normal mode again.
In case of CU malfunction please check the fuse and power to the unit. If both of these are restored and the unit is still not turning
On or is not functioning properly call nearest service center for replacement.
Thermal Protection:
Thermal protection is ensured through an auxiliary bimetallic mini sensor (located near the boiler
temperature sensor) that switches the fan off whenever the temperature rises above a predetermined threshold. The temperature
threshold for the alarm to be activated is 95 °C. This feature prevents the boiler from overheating and the regulator from being
damaged. This type of thermal protection (through a bimetallic strip) ensures that the system returns to its initial condition
automatically
.
Fuse :
Control Unit circuit protection is provided by a 3,15 A fusible safety plug.
CAUTION:
Do not use fuses with higher current values. Placing a fuse with an excessive ampere value may cause your boiler's
control panel to be damaged.
