Panel create a complete factory engineered system.
The control system (FPC) is designed specifically for
each unit. The control system (FPC), with the appro-
priate options, can control , monitor and diagnose those
points that are necessary to maintain optimum perfor-
mances.
There are three options available:
• Factory-mounted End Devices
• Factory-mounted End Devices, factory wired to a
terminal strip in a single enclosure.
• Factory-mounted End Devices, factory wired to a
terminal strip and a controller mounted in a single
enclosure.
The YORK Factory-mounted End Devices Package
consists of end devices that are pre-engineered, fac-
tory installed and tested:
• Binary Inputs – On/Off, Open/Close indication.
Examples: Low Temperature Limit, Filter Status,
Fan Status
• Binary Outputs – On/Off Control by relay.
Example: Fan Start/Stop
• Analog Inputs – Temperature or pressure reading.
Examples: Supply Air Temp, Supply Duct Static
Pressure
• Analog Outputs – 2 to 10 volts DC signal for
modulation control.
Examples: Chilled Water Valve, Damper Actuator,
Variable Frequency Drive
