AFFECTED PAGES DESCRIPTION
3 Conditioned Based Maintenance program information added
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 lo-
cal 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 pro-
gram will include fault detection diagnostics, operation
code statistics, performance based algorithms and ad-
vance rules based rationale delivered by the Johnson
Controls Connected Equipment Portal.
