Installation
C.3. Installing the temperature sensors
The temperature sensor cables must be routed separately from mains voltage
cables and must not, for example, be routed in the same cable duct!
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 sensors suitable for the
specific area of application with the appropriate permissible temperature range.
Caution
Caution
1. Select necessary program/hydraulics.
2. Open controller casing (“C.1. Wall
installation” on page 8).
3. Strip cables by max. 55 mm, insert fit
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 control-
ler.
5. Refit terminal connection cover and
fasten screw.
6. Switch on mains voltage and place
controller in operation.
