• Setting number of units for DHW production (Password 303):
ATTENTION: to correctly set management of units for DHW production, the following guidelines must be
respected:
(1) Modbus address of units: the units must have a specifi c modbus address to be able to be managed properly
by the MULTI CONTROL accessory; this address can only be set from the panel on the unit (for further information
on procedures for setting a serial address on the units, refer to its user manual); the addresses to be set on the
units depend on the number and function which the units perform in the system; to clarify which are the correct
addresses to be applied to the units for DHW production, see the summary table on the next page.
(2) Type of unit: if the system is provided with a reserve chiller, this unit will be the one with the highest modbus
address (as indicated in the summary table on the next page); moreover, if the system envisions the both
possibility of a reserve chiller and DHW production enabling, ALL the units of the system must be capable of
producing domestic hot water (therefore they must all be heat pumps or heating only units).
