YORK YK — REMOTE STOP

The Control Center displays REMOTE STOP in this exact wording; the manual lists no other variant. The message is listed among the system shutdown messages, with the meaning given as a cycling shutdown caused by a remote stop command, and it is displayed only while the Control Center is in REMOTE mode.

A remote device — typically an Energy Management System (EMS) — has commanded the chiller to shut down. The manual classifies it as a cycling shutdown, not a safety shutdown. The command arrives through the Remote Stop control signal input, one of the standard remote inputs the Control Center accepts, alongside Remote Start, Remote LCWT Setpoint and Remote Current Limit Setpoint. In the governing-control table the operating point for Remote Stop is described as a contact signal from the remote device. Because the message is displayed only in REMOTE mode, it reflects the remote command and the operating mode.

• A remote device (typically an Energy Management System) has commanded the chiller to shut down.
• The Control Center is in REMOTE mode — the only operating mode in which this message is displayed.

1. Press the MODE key to confirm the active operating mode: REMOTE OPERATING MODE IN EFFECT confirms REMOTE mode, while LOCAL OPERATING MODE IN EFFECT and SERVICE OPERATING MODE IN EFFECT indicate the other modes.
2. Identify the remote device behind the command — typically an Energy Management System wired to the Remote Stop input.
3. Determine whether the remote device has applied, or is about to apply, a separate start signal; the chiller restarts when that signal arrives.
4. Keep the mode constraints in mind: the COMPRESSOR switch must be in RUN position to enable REMOTE mode, the operator cannot locally start the compressor with that switch while in REMOTE mode, but the compressor can always be stopped with the COMPRESSOR switch regardless of the operating mode.
5. If local control is required, change the operating mode: press the ACCESS CODE key and, when ENTER VALID ACCESS CODE is displayed, enter the valid access code with the Entry keys — the characters YORK appear as each digit is entered.

No operator reset is described for this message; recovery is driven from the remote side: The chiller will restart upon application of a separate start signal from the remote device. Since local starting is blocked in REMOTE mode, the restart cannot be made from the COMPRESSOR switch at the panel — it must come from the remote device.
