5. Danfoss Actuator Icon ABN-FBH 230 NC
Thermostatic actuator Icon ABN-FBH 230 NC. For heating circuit distributors and radiators. Individual application and control options. Silent opening and closing of the valve. Easy installation thanks to click closure. Can be mounted in any position (360°), 1 m cable. Suitable for all valves with a thread size of M30 x 1.5 mm (mounting adapter not included).
Application: The ABN-FBH actuator is designed for optimal control of valves on heating circuit distributors. Control is achieved through a 2-point room temperature controller or by pulse width modulation. The actuator from Danfoss enables comfortable regulation of the room climate by demand-based opening and closing of the valve on the heating circuit distributor, radiator, or convector.
You can control the actuator as desired in combination with a floor heating actuator, directly via a wall thermostat with switching output, or in a conventional manner using an electromechanical wall thermostat. The actuator, which is closed in a power-off state, opens or closes the valve silently in about three minutes, with a maximum power consumption of only one watt.
Thanks to the patented sealing method with IP54, the actuator is reliably protected against splashing water. This allows it to be mounted in any installation position. Installation is quick and easy using the appropriate VA80 valve adapter, which must be purchased separately if needed.
The actuator can now be easily clicked onto the valve. It is compatible with all valves from the most common manufacturers such as Heimeier, MNG, Junkers, Honeywell-Braukmann, Oventrop, Comap, Schlösser, and many more that have a thread size of M30 x 1.5 mm.
