board by a 20 wire cable through the cuplung X5.
The mainboard is joined by the individual elements shown in respective power wires
arrangement. When replacing the boiler sensor or mainboard, but not replace the sensor, it is
possible to obtain the temperature difference. In case that the management is used for
example for electric boiler, then it is not required to be mounted room thermo regulator. In
this case jumper J1, which placed on the main board is switched to pos 2 and by trimmer
potentiometer W pos 12 the temperature is set. In all other cases jumper J1 is placed in pos. 1
