HVAC Tech Tip - Controlling a VAV box with the only Pneumatic controller you will ever need.

Описание: In this edition of Tim's Tech Tips, Tim's going to show you how to control a VAV box with a Pneumatic Controller. Controllers like the KMC CSC 3000 are reset volume controllers that are
designed for use on heating or cooling systems with
(normally open or normally closed) VAV terminal
units and (direct or reverse acting) thermostats.
They are sub-master air velocity controllers. Each is
equipped with separate adjustment knobs for minimum
and maximum airflow setpoints. Models are
available with various reset start points. A master
controller, typically a room thermostat, resets the
CSC-3000 between the minimum and maximum
velocity setpoints.
The universal design of the CSC-3000 series is intended
for new or replacement applications that call
for direct or reverse acting reset on normally open or on normally open or normally closed VAV terminal units , which makes them very flexiable. You only need one for your truck and you will be prepared for any vav reset controller replacement.
