This application can only be used in combination with a
maximum of 2 boilers with the same output (in fact, while the
cascade regulator - through fan rpm detection - rises and acts
on the output delivered by the boilers, with simple cascade it is
possible to control the flow temperature, but not the output).
INAIL
Using the "simple cascade" system without the cascade regu-
lator, and installing the common system flow probe Kit code
3.024245 (optional), it is possible to manage:

- a pump for the D.W.H.;
- one booster pump, at most, i.e. a direct zone (it cannot
manage other mixed or direct zones).
Unlike the Cascade regulator, the number of operating hours
are not exactly divided between the connected boilers, rather,
with later requests, the boilers take turns being the first to
start up.
N.B.: In terms of the electrical connection of probes and
pumps, refer to the previous page.
