INSTRUCTIONS
INSTRUCTIONS
Start up
1. Check that all wiring is correct.
2. Check that switch 2 is in the correct positions for the installa-
tion on hand.
3. If everything seems to be OK, connect supply voltage and do
those of the following tests that apply to the installation.
Function test: Cascade control.
1. Set function switch 3 and 5 to position A and switches 1 and
4 to position B.
2. Twist the setpoint knob to the clockwise endposition. LED Y1
should light up and the actuator should open the valve.
3. Twist the setpoint knob to the counter clockwise endposition.
LED Y2 should light up and the actuator should close the
valve.
4. Set function switch 4 to position A and switches 1,3 and 5 to
position B.
5. Twist MIN to the clockwise endposition. LED Y1 should light
up and the actuator should open the valve.
6. Twist MIN to the counter clockwise endposition. LED Y2
should light up and the actuator should close the valve.
Function test: Single sensor control.
1. Set function switch 3 and 5 to position A and switches 1 and
4 toposition B.
2. Twist the setpoint knob to the clockwise endposition. LED Y1
should light up and the actuator should open the valve.
3. Twist the setpoint knob to the counter clockwise endposition.
LED Y2 should light up and the actuator should close the
valve.
After completing the test:
Set the function switches in the correct positions for the installa-
tion on hand.
When running cascade control, set the potentiometer MIN to the
desired minimum limiting value for the supply air temperature
and set the cascade factor on potentiometer CF.

Settings
AQUA24TF/D is on delivery set to values suitable as starting values
for balancing the system.
Final settings must be tried out when the system is comissioned.
Factory settings FS in brackets.
Setpoint
0 - 30°C. Setpoint for the main controller.
(FS = 20°C).
CF
1 - 15. Cascade factor. (FS = 1). The value signifies
the immediate change in the duct controller setpoint
for a 1K step change in room temperature.
(Cascade control only).
Min
0 - 30°C. Minimum duct temperature. (FS = 15°C).
(Cascade control only).
N.B. When running single sensor room temperature control (not
cascade control) CF and Min are inactive.
Function switches
1 and 4 in position B
3 and 5 in position A
1 and 4 in position A
3 and 5 in position B
2 in pos. A = Internal
2 in pos. B = External
