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 30m using a ca-
ble 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 spe-
ci
fi
c area of application with the appropriate permissible temperature range.
Caution
Caution
1. Select necessary program/ hydraulics
2. Open controller
3. Strip cables by 55mm max., insert,
fi
t the
strain relief devices, strip the last 8-9mm
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 (Page 10)
5. Re
fi
t upper part of housing and fasten with
