1. Select necessary program/hydraulics (s. „Hydraulic vari-
ants / Systems / Diagrams“ on page 12)
2. Remove terminal connection cover (s. „C.2.1. Socket“ on
page 7)
3. Strip cables by 55mmmax., insert,
fi
t the strain relief de-
vices, strip the last 8-9mm of the wires (Fig. „C.2.2.“)
4. Open the terminals using a suitable screwdriver (Fig.
„C.2.3.“) and make electrical connections on the controller
5. Re
fi
t terminal connection cover and fasten screw.
6. Switch on mains voltage and place controller in operation.

Installation
The temperature sensor cables must be routed separately from mains voltage cables, and must not, for
example, be routed in the same cable duct!
Caution
Caution
The controller operates with Pt1000 temperature sensors which are accurate to the degree, thus ensuring optimal control of
system functions.
Caution
If desired the sensor cables can be extended to a maximum of 30m using a cable with a cross-section of
at least 0.75mm². Make sure that there is no contact resistance!
Position the sensor precisely in the area to be measured!
Only use immersion, pipe-mounted or
fl
at-mounted sensor suitable for the speci
fi
c area of application
with the appropriate permissible temperature range.
Connect the VFS sensors with the matching jacks.
To prevent damage to the Direct Sensors it is highly recommended to install them in to the return.
When installing the Vortex Flow Sensors (VFS), observe the correct
fl
ow direction!
Instructions for clamps:
1. Insert screw driver into the upper hole. Push the lock
clamp inside down.
Keep the screw driver in this position.
2. Insert cable into the lower opening.
3. Remove screw driver. The clamp will lock the cable.
