pplication The Pressure Independent haracterized ontrol 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 VV reheat coils. This valve is suitable for use in a hydronic system with constant or variable flow. This valve is designed with MT functionality which facilitates the use of various control input.

Wiring iagrams INSTLLTION NOTS ctuators with appliance cables are numbered. Provide overload protection and disconnect as required. ctuators may be connected in parallel. Power consumption and input impedance must be observed. ctuators may also be powered by 24 V. Two built-in auxiliary switches (2x SPT), for end position indication, interlock control, fan startup, etc. Only connect common to negative (-) leg of control circuits. 500 Ω resistor (ZG-R01) converts the 4 to 20 m control signal to 2 to 10 V. ontrol signal may be pulsed from either the Hot (Source) or ommon (Sink) 24 V line. or triac sink the ommon connection from the actuator must be connected to the Hot connection of the controller. Position feedback cannot be used with a triac sink controller; the actuator internal common reference is not compatible. IN4004 or IN4007 diode. (IN4007 supplied, elimo part number 40155). ctuators with plenum cable do not have numbers; use color codes instead. Meets culus requirements without the need of an electrical ground connection.!
