Heating Actuator with Triac is mainly used for the room temperature controller and valve control, can be installed in central Heating/cooling control system. The valve driving supports 230V AC drive and 24V AC, with LED indication for valve status. Moreover, it supports manual operation which is on the front of the device to facilitate engineering commission. Heating Actuator with Triac is a modular installation device for fast installation in the distribution board on 35 mm mounting rails to DIN EN 60 715. The electrical connection is implemented by using screw terminals. The connection to the KNX bus is implemented using the supplied bus connection terminal, and no need an extra voltage supply. The physical address assignment and parameter settings can be used with the engineering tool software ETS (version ETS5.7 or above) with the .knxprod file.

The functions are summarized as followed: 

• Thermal driving can support to 24V AC or 230V AC
