Modbus Addresses For Units For Dhw Production (With Reserve Chiller) - AERMEC MULTI CONTROL Booklet

Modbus addresses for units for DHW production (with reserve chiller):

Type of systems for DHW production:
In these types of units where DHW also has a reserve unit, ALL the units managed by MULTI CONTROL must be capable to
produce domestic hot water (HEAT PUMPS or HEATING ONLY); the reserve unit is always the last one, namely the one with the
highest serial address; this unit will not be activated during the request for domestic hot water, but will only intervene if one or
more of the main units are unusable.
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.
