Start-up - initial settings and functions
8.2.16 Cascade system settings
MENU > FOR SERVICEMAN > 16. CASCADE SET
Used to set the unit as part of a cascade system.
The parameters that can be set for this function are:
16.1 PER_START (standard: 10% - settable: 10%/100%)
Defines the percentage of units that are activated at system start-up.
L
NOTE
The percentage refers to the total number of units in the cascade system, including both Master and Slave
units.
16.2 TIME_ADJUST (standard: 5 - settable: 1/60)
Defines the minutes after which the Master unit checks whether a Slave unit is switched on/o.
16.3 ADDRESS RESET (standard: FF - settable: 0/15)
Sets the unit address, for Slave units only.
L
NOTE
Slave units are auto-addressing and do not require manual address setting. FF is equivalent to setting an
invalid address.
If necessary, set the address manually.
8.2.17 Other HMI settings
MENU > FOR SERVICEMAN > 17. HMI ADDRESS SET
If the unit is controlled with home automation or BMS systems, it is possible to limit access from the HMI to
only certain parameters.
The parameters that can be set for this function are:
17.1 HMI SET (standard: 0 - settable: 0/1)
Defines whether the HMI has limited settings (parameter = 1): in this case it can only manage ON/OFF, mode
change and setpoint.
17.2 HMI ADDRESS FOR BMS (standard: 1 - settable: 1/16)
Defines the unit address for management with BMS systems.
L
NOTE
This parameter is only manageable if the unit has not been limited in point 17.1.
17.3 STOP BIT (standard: 1 - settable: 1/2)
Defines the data exchange protocol between the BMS software and the HMI (it must be the same for both).
