3.20 CONJUNCTION MODE.

In case of simultaneous DHW (Domestic hot water) and system
request, the system decides which to service to perform on the
basis of an alternating logic determined by the system.
It is possible to modify this logic, so that the system simultaneously
deals with both services, using the generators available.
IT IS possible to activate operation in this mode by modifying
the parameter:
Integration/Conjunction mode.
