Damper Actuators are used to control dampers in the open air circulation system. The actuators are designed for placing the damper in the required position and for protecting the water heating coils against freezing. Depending on the damper control system selected, the following actuators are available:
open/close „on-off”
continuous operation: 0..10V. In the latter type, the desired damper position is obtained by applying control signal, ranging from 0 to 10VDC, from the ZW damper position presetting unit.
