KBY Constant pressure electronic control unit

The KBY control module enables you to set and accurately maintain constant pressure in the Zoning systems duct network. The use of this control makes it possible to guarantee balancing of the entire duct network as well as uniform operation of the installation grills and diffusers.

The unit can operate either on a by-pass damper (type ZC/ZQ) via a 24 VDC output or directly with a 0-10V output on an EC/DC fan or a frequency inverter.
