ApplicationThe Pressure Independent Characterized Control Valve is typically used in air handling units on heating and cooling coils, and fan coil unit heating or cooling coils. Some other common applications include unit ventilators and VAV reheat coils. This valve is suitable for use in a hydronic system with constant or variable flow. This valve is designed with MFT functionality which facilitates the use of various control input.

Wiring Diagrams
INSTALLATION NOTES
Provide overload protection and disconnect as required.
Actuators may be connected in parallel. Power consumption and input impedance must be observed.
Actuators may also be powered by 24 VDC.
Actuators Hot wire must be connected to the control board common. Only connect common to neg. (-) leg of control circuits. Terminal models (-T) have no-feedback.
Actuators with plenum cable do not have numbers; use color codes instead.
Meets cULus requirements without the need of an electrical ground connection.
! WARNING! LIVE ELECTRICAL COMPONENTS!During installation, testing, servicing and troubleshooting of this product, it may be necessary to work with live electrical components. Have a qualified licensed electrician or other individual who has been properly trained in handling live electrical components perform these tasks. Failure to follow all electrical safety precautions when exposed to live electrical components could result in death or serious injury.
