Parameters for Next Maintenance Calculation
General Maintenance Settings
• Maintenance Frequency—can be set as one to 12 months or to zero, which disables mainte-
nance calculation
• Max. Bonus—increases the time to next maintenance with the set value, if all components run
optimally (number of starts, average running time)
• Max. Penalty value—decreases the time to next maintenance with the set value, if some compo-
nents run in non-optimum way (number of starts, average running time)
• Last Maintenance—date can be set from service-engineer; informational
• Service-Engineer—name of the service engineer; editable
• Reset—puts all counters of all components, such as (motor, compressors, heaters and humidifier),
at zero and starts a new maintenance calculation (reset to be done after maintenance)
Fans / Heaters / Humidifier Settings and Diagnostics
• Number of starts and Working hours are counted separately since the last maintenance. Total
working hours can be read in the standard working hours window (customer window).
• Average Working Hours is the calculation, resulting from starts and working hours.
• Starts per Day Optimum is the number of starts considered as optimum.
• Starts per Day Worst is the number of starts considered as hunting (worst case).
• Number of Alarms counts the alarms, happened between two service intervals.
• Actual Bonus is calculated from number of starts and average working time. Can be positive
(bonus) or negative (penalty). This value influences the time remaining to the next maintenance.

working hours can be read in the standard working hours window (customer window).
• Average Working Hours is the calculation, resulting from starts and working hours.
• Starts per Day Optimum is the number of starts considered as optimum.
• Starts per Day Worst is the number of starts considered as hunting (worst case).
• Number of HP Alarms counts the high-pressure alarms, happened between 2 service intervals.
• Number of LP Alarms counts the low-pressure alarms, happened between 2 service intervals.
