Connecting hot water sensor

Connect the hot water sensor to the designated terminal 
block. The sensor should be positioned a third way up 
from the bottom in the water heater which is supplied with 
incoming cold water. 
See separate manual for the control system.

6.5 

Connecting sensor for system supply 
temperature

The system supply sensor must always be installed on the 
system’s supply pipe after the auxiliary heater. The sensor 
must be positioned so that the heated water has been able 
to mix properly. 
See separate manual for the control system.

6.6 

Connecting external start brine pump 
(passive cooling option)

Potential free connection between terminal blocks 127-
128 that start the brine pump. This function can be used 
for passive cooling from the brine circuit. Connect to the 
incoming brine pipe. 
See separate manual for the control system.

6.7 

Connecting exchange valve for hot 
water

See separate manual for the control system.

6.8 

Connecting room sensor (option)

•  Remove the front cover from the heat pump.
•  Route the room sensor’s connecting cable through the 

opening in the rear piece up to the connecting block.

•  Connect the sensor to the designated terminal block.

 

See separate manual for the control system.

 

 

Note that the room sensor’s connecting voltage is 

extra low protection voltage. Also note that this is an 
active sensor supplied with 24 VAC.

 

 

24 VAC 1 must not be connected together with:

  

• 24 VAC 2

  

• 24 VDC

  

• Other equipment that uses 0-10V control signal

  

• Signal ground GND

 

 

24 VAC 2 must only be used as power supply to:

  

• External equipment that requires 0-10V control

 

   

signal

  

• Auxiliary modules

 

 

The two separate 24 VAC circuits must never be con-

nected to each other or to protective ground.

 

 

The total power load on 24 VAC 1 respectively 24 

VAC 2 must not exceed 50VA.

6.9 

Connecting pressure and/or flow 
switch (option)

Connect the pressure and/or flow switch for the brine side 
to the intended terminal block 123-124 at the same time 
as removing the bridge. When using both the pressure and 
flow switch. these must be connected in series. 
See separate manual for the control system.

6.10  Connecting start/stop auxiliary heater

Start/stop auxiliary heating connected to terminal block 
133-134 (24 VAC) 
See separate manual for the control system.

6.11  Connecting external buzzer

Active alarm produces 24 VAC out on terminal block 135-
136. 
See separate manual for the control system.

6.12  Connecting system pump

Start/stop of the house system pump 24 VAC. 
See separate manual for the control system.

6.13  Connecting control signal for  auxiliary 

heater

See separate manual for the control system.

 

 

24 VAC 1 must not be connected together with:

  

• 24 VAC 2

  

• 24 VDC

  

• Other equipment that uses 0-10V control signal

  

• Signal ground GND
