Connections
The Slave units are automatically addressed and they do not need to be addressed manually.
For the automatic addressing function to work properly, the units must be connected to the same power supply, shielded and then
turned on together.
Notes:
on the Master unit dip-switch SW9 must be set to “ON”
only the Master unit can be connected to the HMI and during operations the Slave units must not be connected to the HMI
In a cascade system only the Master unit can:
control the main sensors (Tbtu, Tbtl, T5, Tw2, Tsolar, Ta)
control the input signals (such as M1 / M2, room thermostat, adapter board, smart grid, solar input, etc.)
monitor external elements (SV1, SV2, SV3, PUMPO, PUMPC, PUMPD, PUMPS, AHS, TBH, etc.)
Note:
The Slave unit can only control its T1 probe (leaving water temperature) and IBH probe (if its dip-switch is set to ON)
shielded cable – earthed display
heater for network
termination on last unit
