On the back side of the E8 regulator there are two terminal
blocks, of which one is for the mains (230 V) connections and
the other one is for the low tension connections.
The main controls, necessary for the C.H. system manage-
ment and for the boiler control, as well some components
which are part of the boiler house, must be connected to the
terminal blocks.
