YORK RMM MKIVB 1112-2727 Remote Monitoring Module YMC 8214 024 REV 1.0 ID 1119

The YORK RMM MKIVB 1112-2727 is a sophisticated Remote Monitoring Module (RMM) designed specifically for YORK® air conditioning and refrigeration chillers. This module serves as the critical communication link between the chiller’s onboard microprocessor control system (typically a YORK® OptiView™ or similar control center) and a remote building management system (BMS) or facility manager.

Part of the established YORK MKIVB family of controls, this module enables real-time data monitoring, system status alerts, and historical data logging, facilitating proactive maintenance and optimized chiller performance.

Key Features and Functionality:

• Protocol Translation: The primary function of the RMM is to translate the chiller’s native communication protocol into industry-standard languages. It commonly supports protocols like:

  • BACnet MS/TP (Most common for building automation)

  • Modbus RTU

  • LONWORKS (Depending on configuration)
    This allows for seamless integration with most major BMS platforms from vendors like Siemens, Johnson Controls, Honeywell, and Schneider Electric.

• Real-Time Data Monitoring: Provides remote access to a comprehensive set of chiller operating parameters, including:

  • Leaving and Entering Chilled Water Temperatures

  • System Pressures

  • Motor Load and Amperage

  • Operating Status (Running, Stopped, Fault)

  • Setpoints and Control Values

• Alarm and Fault Reporting: Immediately relays critical alarms and diagnostic fault codes from the chiller to the BMS and facility operators. This allows for rapid response to issues, minimizing downtime and preventing potential equipment damage.

• Hardware Identity: The specific part number 1112-2727 and identifiers like YMC 8214 024, REV 1.0, and ID 1119 are used for precise ordering, configuration, and firmware management, ensuring compatibility with specific chiller models and control board revisions.
