Connection options for the PCB (SCU-X01)

The -X01 PCB has two potential-free contacts (status), which can be con­
figured as required. Depending on the setting, a maximum of two messag­
es about the status of the boiler can be transmitted. See table. Select the
messages required using rotary knobs SW1 and SW2. Use rotary knob
SW1 for messages on the status connector X3. Use rotary knob SW2 for
messages on the status connector X4.
