3.
Fit protection pocket in the pipe. If required, use
sealing material (hemp, Teflon tape, or similar).
4.
Insert controller into the protection pocket and snap
it on.
5.
Fill piping system again.
6.
Mount external temperature sensor according to the
Mounting Instructions supplied with it.
Electrical installation
• Ensure that the local regulations for electrical installa-
tions are complied with
• The connecting terminals are located under the flexi-
ble plastic cover
• Make wiring according to the plant documentation. If
not available, use the connection diagrams contained
in these Installation Instructions
• Observe the permissible cable lengths
• Switch on power only when commissioning the con-
troller

Indication of operating state
The red LED indicates the controller's operating state:
• LED lit: Mains voltage present (normal operation)
• LED flashes fast (4 Hz): In test mode
• LED flashes slow (1 Hz): Fault (B2)
The LED is also visible when the cover is fitted.
Commissioning
1.
Remove housing cover.
2.
Lift flexible plastic cover so that you can access the
setting elements.
3.
Make the settings:

4.
Replace flexible plastic cover.
5.
Switch power on. LED for the operating state must
flash (test mode).
6.
Move temperature setting slider to the minimum
value (<5 K) to prove contact Q1–Q3
► If response is wrong, refer to "Troubleshooting"
7.
Move temperature setting slider to the maximum
value (>25 K) to prove contact Q4–Q6.
► If response is wrong, refer to "Troubleshooting"
8.
Switch power off.
9.
Switch controller back to normal operation (set
switch no. 6 to
OFF).
10. Switch power on. LED for the operating state must
light up (normal operation).
11. If a remote setting unit is used, set the controller's
temperature setting slider to EXT.
12. First, set temperature setting slider to the minimum
value, then to the maximum value: Observe the con-
trol. The response may neither be too fast nor too
slow.
► If response is wrong, refer to "Troubleshooting"
13. Adjust the setpoint with the temperature setting
slider.
14. Replace housing cover.
