Conditioned based maintenance
Traditional chiller maintenance is based upon assumed and generalized conditions. In lieu of
the traditional maintenance program, a Johnson Controls YORK Conditioned Based Maintenance
(CBM) program can be substituted. This CBM service plan is built around the specific needs for
the chiller, operating conditions, and annualized impact realized by the chiller. Your local Johnson
Controls Branch can propose a customized Planned Service Agreement that leverages real time
and historical data, delivering performance reporting, corrective actions required and data enabled
guidance for optimal operation and lifecycle assurance. The program will include fault detection
diagnostics, operation code statistics, performance based algorithms and advance rules based
rationale delivered by the Johnson Controls Connected Equipment Portal.
