During the operation of the device some errors could appear.
If the display shows X (X stays for the number 0-5), it means that there is a regulator operation error. The
number shows its reason.
0 - too high temperature on the sensor > 90°C
1 - wrong value on the sensor the value is out of the measuring field
(>99°C)
or the temperature sensor is wrong
connected.
2 - sensor is not connected or the regulation measures the temperature
which
is lower then -40°C in the boiler.
4 - the pressure
detected an error, electric heaters switch off
switch
and
the pump still works for 30 sek.
5 - the cover of the regulation is opened dangerous contact with 400V
tension. Therefore the regulation switches off the heaters
and the pump
(continuation of the normal functioning possible after setting the originary
operating mode. If this error repeatedly appears, the authorized person
should check the device.
If the systems falls into some kind of stand by (which practically occurs), when the installed power is not enough to
bring the system exactly on the desired temperature level, whereat the system is not cooling down (for example the
desired temperature is 70°C and at the temperature level of 67°C with activated power lower then maximal, the
system reaches the stand by, which means the temperature level remains invariable), after about 10 minutes the
system shall increase the power by itself.
