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. For this purpose it is necessary to adjust the
reading by trimmer potentiometer P2.
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
