5. If the status of the system is set to "Summer and san" or "Winter and san", the priority is given on the production of
domestic hot water; therefore the system goes first in domestic hot water production, when the sanitary is satisfied, the
system switches the mode to summer or winter operation.
(*)If from: System main page ‐> "Status setup" ‐> "System" you select only the "Sanitary":
to put the sanitary in "OFF" or "Programmed" or "Manual" mode, then go to "Status setup", enter to "Chiller" and from there select
the status (in this case both "Manual" and "Manual eco" set the chiller in the sanitary manual mode).
Note: Once the status is set, you must wait a minute to ensure that communication with the on‐board control of the units in the
network is going and the units themselves are activated in the set status.
