1. Select necessary program/hydraulics
(Fig. B5 resp. D.1 - D.20)
2. Open controller as described under
C.1.
3. Strip cables by 55 mm max., insert,
fix the strain relief devices, strip the last
8 - 9 mm of the wires (Fig. C.2.1)
4. Open the terminals using a suitable
screwdriver (Fig. C.2.1) and make
electrical connections on the controller
(s. D.1 - D.20)
5. Refit upper part of housing and
fasten with screw.
6.Switch on mains voltage and place
controller in operation.
C.3 Installing the temperature sensors
The controller operates with Pt1000 temperature sensors which are accurate to the
degree, thus ensuring optimal control of system functions.
If desired the sensor cables can be extended to a maximum of 30 m using a cable
with a cross-section of at least 0.75 mm². Make sure that there is no contact
resistance! Position the sensor precisely in the area to be measured!
Only use immersion, pipe-mounted or flat-mounted sensor suitable for the
specific area of application with the appropriate permissible temperature range.
The temperature sensor cables must be routed separately from mains voltage
cables, and must not, for example, be routed in the same cable duct!
