Modbus addresses for units for DHW production (without reserve chiller):
Type of systems for DHW production:
The fi rst three types of systems have one or more units for DHW production, however they can have other COOLING ONLY
chillers for the system (MULTI CONTROL manages a maximum of 4 units); in this case, it is MANDATORY that the units used for
production of domestic hot water be set with the addresses specifi ed in this table and that eventual cooling only chillers be set
with the serial addresses remaining available.
Remember that to identify the units managed by MULTI CONTROL, the addresses available are:
Unit number 1 = Modbus Address 200.
Unit number 2 = Modbus Address 201.
Unit number 3 = Modbus Address 202.
Unit number 4 = Modbus Address 203.

The Modbus serial addresses must be set on the units by means of their on-board control panel.
