Necessary accessories
Accessories list
The second circuit set:
• A second circuit clip-in kit (CID)
• A mixing valve motor (M)
• A 3 ways mixing valve (VM)
• A QAD 36 flow sensor
A room temperature sensor (QAA 73)
nd
A 2 circuit pump (Q2)
- Refer to their respective fitting instructions
2.2.1 - Without room sensor
The flow temperature of each circuit is defined by
the heating curve for that circuit.
This temperature is corrected by using the boiler
heating potentiometer (setting from 17°C to 23°C).
Correction of the room temperature
!
using the heating potentiometer acts on
both heating circuits simultaneously.

2.2.2 - With room sensor
Only one QAA73 room sensor can be connected
to the LMU. It can control one circuit.

The sensor defines the flow setting required as well
not supplied
as the domestic hot water temperature and sends
them to the boiler control on the basis of the outside
temperature, room temperature and various other
parameters.
The domestic hot water potentiometer is then di-
sabled when the room sensor is connected.
In this case, the set point of CC1 is set on the boi-
ler's heating potentiometer and the CC2 set point on
the QAA73.210.

QAA 73 = 50m.
When there are 2 circuits to be connec-
ted, KonfigHks (parameter 553) must be
set to 10.
The shunt positioned on the X10-02 ter-
minal must remain in place.
