Actuator with ‘First Open’ function
When delivered, the actuator is normally open in a de-energised state, thanks to the First Open function. This enables
heating mode to run even if the electric wiring is not yet completed.
When subsequently commissioned and with the application of power (for longer than 6 minutes), the First Open function
is automatically unlocked so that the actuator becomes fully operational.
