Issue:
can the changeover bypass damper run stand alone?
Resolution:
no
the CCP3 is required
the changeover bypass damper reads flow and SAT
the changeover bypass damper position is commanded by the CCP3
the VAV drive the damper to the position commanded by the CCP3
To control a bypass damper in a stand alone application, use am MP501.
You will need a duct static pressure sensor from Kele.
Use a 4 to 20 milliamp or 0 to 10 VDC sensor.
The MP501 can use a 3 wire floating point output (2 BOPS) to control the air valve.
