The B2 and B3 probe must be connected to the prewired cable
provided with the heat pump and locate inside of it.
Version 2 - A relè to manage DHW or auxiliary
integration.
If you want to manage a 3-way valve to domestic management
or for the ignition of an electrical resistance / boiler, the terminal
presents the relè K3 suitabe for this management.
For standard connections make reference to the table shown in
version 1. Here below is shown the table with the contacts for
the connection of the relé K3

Version 3 - Two relès, to manage DHW and
auxiliary integration.
If you want to manage a 3-way valve for the domestic
management and in the same time the ignition of an electrical
resistance / boiler, the terminal presents two relès: K1 for the
management DHW and K3 for the auxiliary integration.
For standard connections make reference to the table shown in
version 1. Here below is shown the table with the contacts for
the connection of relès K1 e K3.
