On the display
The panel prints this message as Control panel - Schedule. In the manual's display description the same message appears in capitals — CONTROL PANEL - SCHEDULE — on the System Details line, shown together with the status message displayed on the System Status line.
What it means
The manual lists this entry under the cycling faults, but it reports a planned stop rather than a measured fault: the schedule feature has been enabled and the chiller has been shut down in accordance with the schedule entered
. The display-messages part of the manual also places Control panel - Schedule in the soft-shutdown context: while the unit performs any soft shutdown, an immediate stop initiated with the red safety switch — or the occurrence of any fault other than the soft-shutdown messages — terminates the soft shutdown, and the unit immediately performs a system coastdown.
Why it appears
- The schedule feature has been enabled, and the chiller has been shut down in accordance with the schedule entered in the control panel.
What to check
- Look at the schedule entered in the control panel: the shutdown should correspond to it, and the schedule tells you the next scheduled start time.
- Bear in mind that
This feature requires an active run command to function correctly.
- If the Run/Stop Control is set to "Local", set Local Start on the Home screen to RUN.
- If the Run/Stop Control is set to "Hardwire" or "BAS", set Local Start on the Home screen to RUN as well.
- With the Run/Stop Control set to "Hardwire" or "BAS", also make sure the BAS provides a run signal after the schedule has been enabled.
- If LOCAL STOP is displayed on the System Details line in addition to the schedule messages, Local Start is not set to RUN — set Local Start to RUN.
Setpoints and thresholds
- Run/Stop Control — set to "Local", "Hardwire" or "BAS"; which run command the schedule needs depends on this setting.
- Local Start (Home screen) — must be set to RUN for the schedule to work, whatever the Run/Stop Control setting; otherwise LOCAL STOP appears on the System Details line.
- Schedule feature — must be enabled for the unit to follow the schedule entered; when enabled, the unit restarts at the next scheduled start time.
Reset and restart
No reset action is described for this message, and none is needed: the shutdown follows the entered schedule, and The unit restarts at the next scheduled start time.
Questions engineers ask
What does Control panel - Schedule mean on a YORK YK chiller?
It is a cycling-fault message telling you that the schedule feature has been enabled and the chiller has been shut down in accordance with the schedule entered. It is a planned stop, and the unit restarts at the next scheduled start time.
How do I reset or clear Control panel - Schedule on a YORK YK?
No reset is described and none is needed. The unit restarts automatically at the next scheduled start time, because the shutdown follows the schedule entered in the control panel.
Why does my YORK YK show LOCAL STOP together with the schedule message?
LOCAL STOP is displayed on the System Details line when Local Start on the Home screen is not set to RUN. The schedule feature requires an active run command to function correctly, so set Local Start to RUN.
Does the YORK YK schedule feature need a run signal from the BAS?
Yes, when the Run/Stop Control is set to "Hardwire" or "BAS": Local Start on the Home screen must be set to RUN and the BAS must provide a run signal after the schedule has been enabled. With the Run/Stop Control set to "Local", setting Local Start to RUN is what the manual asks for.
