Functions of the heat exchanger
4.1
Parallel operation
This function leads to all boilers working constantly in parallel (
no lag/lead sequence control
).
The boilers start operating one after the other, taking into account the programmed time sched-
ules:
Min. deactivation time
and
Sequence delay
as well as taking into account
Temperature to
enable lag/lead sequence
.
