elements
Indication of operating state
The red LED indicates the controller's operating state:
• LED lit: Mains voltage present
• LED flashes: In test mode
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:
Switching differential (switches no. 1 and 2)
−
Operating mode (with / without minimum charging
−
temperature, switch no. 3)
Test mode (switch no. 4 =
−
Response of changeover contact in test mode:
−
(switch no. 5)
4.
Replace flexible plastic cover.
5.
Switch power on. LED for the operating state must
flash (test mode).
6.
Changeover contact Q1–Q2/Q3 must respond in
accordance with the setting of switch no. 5.
► If response is wrong, refer to "Troubleshooting"
7.
Switch power off.
8.
Change position of switch no. 5.
9.
Switch power on.
10. Changeover contact Q1–Q2/Q3 must respond in
accordance with the setting of switch no. 5.
► If response is wrong, refer to "Troubleshooting"
11. Swich power off.
12. Switch controller to normal operation (set switch no.
4 to
)
13. Switch power on. LED for the operating state must
light up (normal operation).

Test mode
Control mode
Changeover contact Q1–Q3 closes
(control ON)
Changeover contact Q1–Q2 closes
(control OFF)
)
14. If a remote setting unit is used, set the controller's
temperature setting slider to EXT.
15. First, set temperature setting slider to the minimum
value, then to the maximum value: Observe the
control. The response may neither be too fast nor
too slow.
► If response is wrong, refer to "Troubleshoot-
ing"
16. Adjust the setpoint with the temperature setting
slider.
17. Replace housing cover.
Troubleshooting
Wrong response
Valve does not re-
spond
Valve travels in the
wrong direction
Valve remains in one of
its end positions
Control response too
slowly
Control is instable

Montage
Lieu de montage
Température ambiante maximale admissible = 50 °C
• Dans le fournisseur de chaleur : dans la partie la plus
chaude
• Dans le récepteur de chaleur : dans la partie la plus
froide
• Dans le collecteur solaire : immédiatement à la sortie
Montage
Le montage s'effectue avec une gaine de protection.
Procédure :
1.
Purger la canalisation ou le système
2.
Choisir la position de montage comme suit :
max. 15°
Le régulateur ne doit pas être retourné ; l'entrée de câble de doit pas
se trouver en haut.
Le plongeur doit pénétrer à une profondeur minimale de 60 mm

Possible causes
• Valve not connected
• No power supply
• Controller terminals Q2 or Q3
incorrectly wired
• Controller and external sen-
sor mixed up
• Sensor not connected
• Temperature setting slider is
set to EXT and there is no
remote setting unit connected
• External sensor not con-
nected or short-circuit
• Reduce switching differential
• Increase switching differential
max. 15°
