LCN-AVC

The LCN-AVC is an electrothermal actuator for radiator valves with 0-10 V control. It can be connected to valves of various manufacturers by means of adapters. The actuator is intended for operation on LCN bus modules from year of manufacture 04/2008. All LCN actuators are normally closed.

The actuating mechanism operates with a PTC-heated expansion element and a compression spring. The expansion element is heated by applying the operating voltage and the integrated plunger is moved as a result. The force generated by the movement is transmitted to the valve tappet and opens or closes the valve. The LCN-AVC with 0-10 V control is used when several radiators in large rooms are to be controlled by the same controller. Each actuator measures its valve to ensure that the heating output is distributed evenly to all radiators during parallel operation, regardless of the valve characteristics. Up to five LCN-AVC per 0-10 V output can be operated in parallel on the LCN-HU

Fields of application:

• Decentralized heating and air conditioning control for radiators.

The actuator is intended for operation on LCN bus modules from year of manufacture 04/2008. With older bus modules it can be used as a valve switch.
