4.3 Control board
The control board (S) is inside of the electrical panel in the wall dividing.
The auxiliary connections (probes, remote terminal, alarm) are made by
inserting the cables form the outside into the electrical panel.
To do this, use cables gland located on the base of the unit to the plug-in
screw terminals on the control board.
