If the status of the system is set to " san" or " san", the priority is given to the production of domestic
hot water; therefore the system goes first to domestic hot water production, when the DHW is satisfied, the system
switches the mode to summer or winter operation.
(*) If from: System main page -> "

" you select only "
Sanitary
":
to put the DHW at "

" mode, go back to "
Status setup
", enter "
Chiller
" and from there select the
status (in this case both "
Manual
" and "
Manual eco
" set the chillers in DHW manual mode).
Note:
once the DHW status is set from the Hi-T2 control panel, you must wait about a minute to ensure that communication with
the on-board controls of the units in the network is successful and the units themselves are activated in the set status.
