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
When used as a controller
1. Remove housing cover.
2. Lift flexible plastic cover so that you can access the
setting elements.
3. Make
the
settings:
−
Operating mode (switches no. 1 and 2)
−
Control mode and (with PI mode) integral action
time (switches no. 3 and 4)
−
Test mode: Switch no. 5 =
−
Outside temperature compensation (when using an
outside sensor)
−
P-band Y1 (potentiometer 5) and Y2 (potentiome-
ter 4)
−
Setpoint increase or decrease (slider 3)
4. Replace flexible plastic cover.
5. Switch power on. LED for the operating state must
flash (test mode).
6. First, set temperature setting slider to the minimum
value, then to the maximum value: Actuating device(s)
must travel to the minimum or maximum position.
►
If response is wrong, refer to “Troubleshooting”
7. Switch power off.
8. Switch controller to normal operation (set switch no. 5
to
).
9. Switch power on. LED for the operating state must
light up (normal operation).
10. If used, activate auxiliary functions (setpoint change-
over, load-dependent switching contact, etc.).
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 “Troubleshoot-
ing”
13. Adjust the setpoint with the temperature setting slider.
14. Replace housing cover.
As a limiter
1. Switch on the temperature control.
2. Remove housing cover (limiter).
3. Lift flexible plastic cover so that you can access the
setting elements.
4. Choose operating action according to the following
table:

5. Make the following additional settings:
−
Control mode: P (switch no. 3 =
, switch no. 4 =
)
−
Test mode: Switch no. 5 =
−
P-band Y1 on approx. 25 K
6. Replace housing cover.
7. Switch power on. LED for the operating state must
flash (test mode).
8. Check function depending on the type of limitation:
With minimum limita-
tion:
With maximum limitation
Set temperature setting
slider to the maximum
value:
Controller must increase
the temperature (heating
valve must open, cooling
valve must close)
Set temperature setting
slider to the minimum
value:
Controller must reduce the
temperature (heating valve
must close, cooling valve
must open)
►
If response is wrong, refer to “Troubleshooting”
9. Switch power off.
10. Switch limiter to normal operation (set switch no. 5 to
)
11. Adjust the limit temperature.
12. Replace housing cover.
