Easy user access to airflow sensor inputs. Floating hot water, two-stage electric or modulating hot water heat. Provides nonlinear floating algorithm for velocity control loops. Individual zone pressurization for supply and exhaust control. Motion sensor interface, via network, for enhanced energy savings.
Supports pressurize and depressurize, night purge, and morning warmup sequences.
Actuator included in W7751G mounts directly onto VAV box damper shaft and has up to 35 lb.in. Both controller housing and actuator are UL plenum rated. This VAV Box Controller provides Pressure Independent air flow control and Pressure Dependent damper control. VAV systems generally provide cool air only to the zones. The W7751G Controller provides two additional outputs that control VAV box reheat coils.
