The YORK CARRIER RMM MKIVB (Remote Monitoring Module) is a sophisticated, microprocessor-based control and monitoring panel designed for use with YORK and CARRIER centrifugal and screw chillers. The specific model 1112-2727, also identified as YRC 8214 013 REV 1.0, is a crucial component for providing remote access, real-time data, and system control.

This module acts as the primary communication gateway between the chiller’s internal microprocessor control center (typically a YPIC, Style A, or PIC board) and external building management systems (BMS), remote monitoring stations, or service tools.

Key Features and Functionality

• Model: RMM MKIVB (Mark IV, Version B)

• Part Number: 1112-2727

• Manufacturer Codes: YRC 8214 013 REV 1.0

• Identification: ID 0736 4087 (Likely a unique serial or batch number for tracking)

1. Remote Communication Gateway: The primary function is to translate the chiller’s native data protocol into a standardized format (typically BACnet MS/TP, Metasys N2, or other common protocols) that can be understood by a wide range of Building Management Systems (BMS) and energy management systems.

2. Real-Time System Monitoring: It provides continuous, remote access to critical chiller operating parameters, including:

   • Leaving & Entering Chilled Water Temperatures

   • Supply & Discharge Refrigerant Temperatures and Pressures

   • Motor Current and Voltage

   • Chiller Status (Running, Stopped, Fault)

   • Alarm and Safety Status

   • Setpoints and Operating Hours

3. Remote Control Capabilities: Authorized users can perform essential control functions from a remote location, such as:

   • Starting and Stopping the chiller

   • Adjusting temperature setpoints

   • Resetting faults and alarms

   • Scheduling daily or weekly operation

4. Diagnostics and Troubleshooting: The module is essential for advanced diagnostics, allowing service technicians to monitor system trends, view active and historical alarms, and pinpoint issues without needing to be physically at the chiller, reducing downtime.

5. Compatibility: This specific MKIVB model is designed to be compatible with a wide range of older YORK and CARRIER chillers that were originally equipped with the Mark IV control system. It is a common upgrade or replacement part for facilities maintaining legacy equipment.

Common Applications

• Commercial HVAC Systems: Office buildings, hospitals, universities, and data centers.

• Industrial Process Cooling: Manufacturing plants requiring precise temperature control.

• Any facility with a YORK or CARRIER centrifugal or screw chiller that requires integration into a central BMS for efficient facility management.

Technical Specifications (General)

• Input Power: Typically 24 VAC, sourced from the chiller’s control circuit.

• Communication Protocols: Supports legacy protocols like Carrier CCN (Carrier Comfort Network) and/or standard options like BACnet MS/TP. The specific protocol is often determined by configuration.

• Physical Connection: Connects via a dedicated data link to the chiller’s main control board and provides terminals for connection to the BMS network.

• Revision: REV 1.0 indicates the initial hardware revision of this specific board.
