Description
Power supply: 230V/50Hz
Opening cross-section: 100mm
Damper to be built into a ventilation duct with a circular cross-section.
Insulated with special material with thermal insulation and sound absorption properties.
It can be used on the duct supplying air for combustion to the fireplace. When we are not burning in the fireplace, the damper is closed, and when we are burning, the damper is open. Thanks to the ability to open the damper to an intermediate position, you can regulate the burning speed in the fireplace.
It works perfectly to protect a water jacket fireplace installation from overheating. When the temperature in the installation rises above the set dangerous level, the damper closes - cuts off the air supply for combustion and the fireplace slowly goes out. When the temperature drops below the dangerous temperature, the damper opens - the fireplace reignites.
Connection:
5 cables come out of the actuator:
* 1 - common (N so-called "neutral")
* 2 - closing the damper (L so-called "phase")
* 3 - opening the damper (L so-called "phase")
* 4 - signal (on this wire there is phase when the damper is closed)
* 5 - ground
