X3.6
X3.7
Power-OFF (jumper fitted at the fac-
tory)
Requires floating contact:
■
Closed: Heat pump operational
■
Open: Heat pump shut down
■
Breaking capacity 230 V~, 0.15 A
Remove jumper when connecting.
Note
■
No parameters need to be set
■
The compressor is "forced" off as soon as the contact
opens.
■
The power-OFF signal switches off the power supply
to the relevant component, subject to the power sup-
ply utility.
■
For the instantaneous heating water heater, the
stages to be switched off can be selected (parameter
"Output for instant. heating water heater at pow-
er-OFF 790A").
■
The power supply for the heat pump control unit
(3 x 1.5 mm
2
) and the cable for the power-OFF signal
can be combined in a single 5-core cable.
For further information regarding power-OFF: See
chapter "Power supply".
