Unlocking
•Manual unlocking: shortly press the unlocking button (1) once.
•Remote unlocking: by interrupting the power supply.
•Automatic unlocking: the fusible link reacts as soon as the temperature in the duct reaches 72°C.
Resetting
•Motorised resetting
1. Switch off the power supply for at least 5sec.
2. Power the actuator (respect the prescribed voltage) for at least 75sec.
3. The resetting stops automatically when the end of range is reached (damper open).
•Manual resetting
1. Open the battery compartment (4) and press a 9V battery against the contact springs. Hold this position until the LED
(3) emits a continuous light.
2. Control whether the indicator (2) indicates that the damper blade is open :
Remove the battery, the LED fades away.
3. Close the battery compartment.

If the LED (3) is continuously on, the resetting is complete and the motor is powered.
i
If the actuator detects voltage on the power cable, a brief contact of the battery is enough to start the resetting
process.
i
The power supply of this actuator cannot be individually replaced. If the cable is damaged, the whole unit must be
discarded and replaced.
i
The housing of the mechanism contains a temperature sensor. When the temperature in the housing exceeds 72°C,
