Regulation
9.0. REGULATION
The regulator of the El-Cm measures the temperature and compares it with the set up (desired) temperature. On this
basis it searches for the optimal apportionment of the power used for the system heating to the desired temperature.
The regulator is switched off/on by means of the room thermostat (by turning off the 230V supply). This regulator is self
accommodating to the system in which it is integrated, because immediately after the start-up it finds the optimal
power regime in order to maintain the temperature level as much as possible near to the desired level. In the same
time it reaches the minimum energy consumption, by accomplishing the optimal balance. On the steering board is
visible an display, the buttons and the LED-diode. The buttons are aimed to change displayed values and to choose
adjustable parameters inside the regulator. During the operation, the display shows the measured temperature. By
pressing the button P , after 6 seconds the display shows the set up temperature.

POSSIBLE PARAMETER CHANGES:
Setting the desired electric boiler temperature
By pressing the button P , after the desired temperature level has been displayed and simultaneously pressing the
pointer up , the LCD- display shall show the temperature in the MOD, in which the desired temperature can be
chosen. This is marked by points on the display.
By pressing the button up and down , the desired temperature level can be changed. After the display has shown
the desired temperature, the button should not be pressed any more. After few seconds the regulator shall reestablish
normal functioning and start to display the measured temperature.
The regulation memorize the set up parameters!
