Example: El-Cm Compact 12kW
Always after the start-up the electric boiler is warming up intensively, until the desired temperature
level has been reached.
When the desired temperature level has been reached, the regulator steers the operation of the
electric boiler allocating the power of activated heaters depending to the desired temperature to
be reached, step by step, i.e. 12 kW, 6 kW, 4 kW, 2 kW (MOD1). If by allocating of such power
levels the desired temperature can not be reached, the regulator recognizes that the power has to
be increased, therefore it reallocates the power as follows: 12 kW, 6 kW, 4 kW (MOD 2). If this is
not enough the regulator reallocates once again the power in following way: from 12 kW and 6 kW
(MOD 3). Leastways, the MOD 4 shall be activated, in which the electronic devices operate only at
12 kW level, and the modulation or the energy saving operation does not function. This could
mean that the whole system is oversized for the heater's capacity.
ERRORS
During the operation of the device some errors could appear.
If the display shows
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
or the temperature sensor is wrong
2 - sensor is not connected or the regulation measures the temperature
is lower then -40°C in the boiler.
4 - the pressure
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
(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.
