Enter in “
Network scanning
”;
5.
press the confirmation tick near the word "
Start:
" and wait the system to scan the network;
6.
at the end of scanning phase, the system should find all the chillers (max 7 in cascade) and all the fan coil units of the same
network. If the number of fan coils found does not match those installed, then the wiring is not done correctly.
If one or more fan coils that were correctly addressed and detected disconnect from the network (for example in case of
fan coil power failure), the centralised keyboard proceeds with updating the number of fan coils actually in operation in the
system with a delay of 2 minutes from the occurrence of the failure, displaying an Error message after the update. When
the disconnected fan coils are reconnected, the centralised keyboard recognises them automatically, preserving the
previous settings.

SOLAR MANAGEMENT
This function is not totally configurable by the Hi-T2 controller. It is necessary to act directly on the chiller/heat pump controller by
setting the parameters H85 at 39, H86 at 38 and H103 at 30. The enabling is definitive by configuring the parameter S01 at 1 and
configuring the relative S parameters also by means of the Hi-T2 remote controller.

OPERATION OF CONNECTED UNITS
4.6.1
SWITCHING ON/OFF
When the zones have been configured and the fan coils associated, you may proceed with the “first start-up” of the connected
