5.7 ELECTRIC CONNECTIONS CONTROL UNIT
WARNING! Before any modification to the electric system of the thermal
cooker or to the connections of the control unit, you must disconnect the de-
vice from AC power.
The electronic control unit of the thermal
cooker is already installed and programmed,
so it is ready for use. According to the kind of
installation you will make, it could be neces-
sary to make further connections to manage
internal devices of the thermal cooker.
The additional connections may be useful and
necessary if there is another heat generator
on the same thermosanitary circuit of the
thermal cooker. In this situation, when the
thermal cooker works, it must prevail on the
other generator. The additional connections
allow to obtain automatically this prevalence
and optimize the working of the system.
