Johnson Controls C500ECC-701 DSC-1000 Reset Controller [Refurbished]

The Johnson Controls C500ECC-701 is the repair / exchange unit for the DSC-1000 Series two loop reset controller. The -701 suffix identifies it as a repair part rather than a new-installation code: Johnson Controls' ordering guidance for this platform states that a "-700" repair part can be ordered through normal ordering procedures, with credit given for the exchanged item.

Functionally it is the DSC-1000 two loop reset controller, documented by Johnson Controls as configurable to control two loops with setpoint reset from a second sensor, so each loop's setpoint can be driven automatically from another measured variable - most commonly outdoor air temperature. Each loop is structured as an analog input to analog output sideloop and the control type is PI control with a reset schedule. DSC-1000 controllers operate standalone and can also be brought onto a Metasys network through a Metasys Integrator.
