Terminals Function Explanation
225.1
Heating circuit pump of the heating
circuit with mixer M2/HC2
Connect a temperature limiter to restrict the maximum
temperature for underfloor heating circuits (if installed)
in series.
Connection values:
■
Output: 100 W
■
Voltage: 230 V~
■
Max. control current: 4(2) A
225.2
Mixer motor control, heating circuit
M2/HC2
Mixer closed signal
Connection values:
■
Output: 10 W
■
Voltage: 230 V~
■
Max. control current: 0.2(0.1) A
225.3
Mixer motor control, heating circuit
M2/HC2
Mixer open signal
Connection values:
■
Output: 10 W
■
Voltage: 230 V~
■
Max. control current: 0.2(0.1) A
Indoor unit: Luster terminals (signal and safety connections)
Set the required parameters during commissioning:

Terminals Function Explanation
X3.1 Switched phase Via control unit ON/OFF switch
Note
Observe the total load 1000 W of all connected compo-
nents.
X3.6
X3.7
Power-OFF (jumper fitted at the fac-
tory)
Requires floating N/C contact:
■
Closed: Heat pump operational
■
Open: Heat pump not operational
■
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.
