Controller and sensor PCB (sensors)

Set the required parameters during commissioning:
See page 39 onwards.
Plug Sensor/component
F0.1/F0.2 Outside temperature sensor
F0.2/F0.3 Radio clock receiver (on site)
F4 Buffer temperature sensor
F6 Cylinder temperature sensor, top
(X25.5/X25.6)
F7 Cylinder temperature sensor, bottom
(X25.7/X25.8)
F11 Contact humidistat 24 V
Note
If the contact humidistat of the NC-Box is used when cooling, set jumper,
otherwise the heat pump will not start (message "CA Protectn device prim-
ry").
F13 Flow temperature sensor, system (downstream of the heating water buffer
cylinder and external heat generator)
F14 Flow temperature sensor, cooling circuit: Heating circuit without mixer
A1/HC1 or separate cooling circuit SKK
F16 Room temperature sensor, cooling circuit
Required for separate cooling circuit SKK
■
Recommended for heating/cooling circuit without mixer A1/HC1
■
F20 Boiler water temperature sensor, external heat generator
KM-BUS (wires interchangeable)
aVG
Use the KM-BUS distributor (accessories) if several devices are connected.
KM-BUS subscribers (examples):
Extension kit, mixer for heating circuit M2/HC2
■
Remote control: Set the heating circuit allocation on the remote control.
■
EA1 extension, AM1 extension
■
Modbus 2 (wires not interchangeable)
sVA
Connection for photovoltaic system energy meter
J3 Jumper for terminator, Modbus 2
Terminator active (delivered condition)
Terminator not active
J4 Jumper for setting master/slave, Modbus 2
Heat pump control unit is slave.
Heat pump controller is master (delivered condition).
