Explanation
Connect a temperature limiter to restrict the maximum
temperature for underfloor heating circuits (if installed)
in series.

Explanation
Via control unit ON/OFF switch
Note
Observe the total load 1000 W of all connected compo-
nents.
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 components, 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

2
(3 x 1.5 mm ) and the cable for the power-OFF signal
can be combined in a single 5-core cable.
