DHW
The signal for DHW heating can be taken from the "WW" terminal.
When DHW heating is active, 230 V is applied to the terminal.
9.6.3 Connecting external components
WARNING Electrocution
Only components that operate with safety extra low
voltage (SELV) and that ensure secure separation from
the mains voltage supply may be connected to the low
voltage terminals of the appliance.
Connecting other components can make parts of the ap-
pliance and connected components live.

f
Only use components which have been approved by
us.

Material losses
Before connecting the control voltage to the function
module terminal area, you must have connected the XD05
heat pump bus cable connector and the XD01 heat pump
power supply to the heat pump control panel (see chapter
"Specification / Wiring diagram").
