5.1.1 Accessing the parameters of a PCB
Depending on the configuration of the installation, one or more PCBs are
installed in the heat pump to run the circuit(s).
Installation type
PCB(s) installed
1 circuit
EHC-02 (heat pump control system)
2 circuits
EHC-02 (heat pump control system)
SCB-04 (management of a second circuit)
Installation with 1 circuit
An installation with a single circuit will be run by a single PCB, the EHC-02
PCB.
1. The name of the PCB is displayed on the screen.
Installation with 2 circuits
Note
When commissioning the heat pump, the PCB displayed is
EHC-02.
To run an installation with a second circuit, it is necessary to install a sec
ond PCB: SCB-04.
The installer can access the parameters and settings for each PCB.
To switch from one PCB to another, proceed as follows:
1. Press the two right-hand keys at the same time.
