3.10 Wellness—Next Maintenance Calculation
The next maintenance calculation, as well as the diagnostics feature, will help keep the cooling unit
running at peak performance to ensure minimum component stress and maximum reliability. The
diagnostics will help the service engineer evaluate the unit’s operation since the last maintenance.
3.10.1 Calculating Next Maintenance and Diagnostics
If the unit includes any of the following components, they are included in the calculation:
• Fan(s)
• Compressor 1
• Compressor 2
• Electric Heaters
• Humidifier
For each component, the next maintenance will be calculated from the following parameters:
• Standard service interval (1, 2 or 4 times a year) (to be set)
• Working hours (counted)
• Number of starts (counted)
• Average running time (calculated)
• Optimum number of starts per hour (to be set)
• Maximum number of starts per hour (to be set)
• Maximum bonus to enlarge time to next maintenance (to be set)
• Maximum penalty to reduce time to next maintenance (to be set)

when service will be needed, for the entire unit as well as for individual components. This assists in
scheduling maintenance calls and helps pinpoint components likely to require service.
