On the display
The chiller display shows the message exactly as printed: Warning - Yearly service required - Contact JCI. This is the only wording the manual gives for the message. The manual classifies it as a warning and calls it a manual reset warning, and its text asks the user to contact JCI.
What it means
This is a maintenance reminder for the yearly service interval. The manual describes it as a manual reset warning that is set when the time since the last yearly service crosses one of two limits — a count of days or a count of operating hours. The message text itself directs the user to contact JCI.
Why it appears
- Days since the last yearly service have reached 365 days or more.
- Operating hours since the last yearly service exceed 2,890 hours, which the manual equates with 33% of the run hours of a full year.
Setpoints and thresholds
- Day count — the warning sets once 365 days or more have passed since the last yearly service.
- Hour count — the warning sets once operating hours since the last yearly service pass 2,890 hours, given as 33% of the run hours of a full year.
Reset and restart
Clearing the warning is done by hand. The manual states: The warning can be reset when the Maintenance Acknowledge key is pressed, Yearly Service is selected, and the code 0726 is entered.
The same action also resets the yearly service days timer and the yearly service hours timer.
