Mount the enclosed sensor (G)
with copper pipes and screw
connections (K-1 and K-2) between
the flow and return ball valve (A-2
and F-2).
Observe the marking on the sensor
housing: P1 = flow; P2 = return.
The bend of the copper pipe points
backwards. The sensor cable is
led out at the top of the insulation.

Repeat these steps for all the

Mount the actuator (see page 11)
and run the cable backwards.
12.
Only for MC42: Connect the power
supply of the actuator to the heating
controller.

Fix the rail to the pipe observing
a distance of 15 cm above the
ball valves (see figure).
For DN 40 use the inner holes,
for DN 50 the outer holes.
