Table 3: Setpoint Control by Microprocessor

**Modification to the K3 common alarm relay on the microprocessor controls of the Environmental unit is necessary to enable remote on/off – this modification will necessarily eliminate the common alarm relay output. Refer to the Installation / Operations Manual of the Environmental unit, or consult Liebert Environmental Support.

Note that if the high/low temperature and humidity alarm setpoints are disabled at the unit controls, then the MR1 will display 00 for the setpoint. The MR1 is not able to remotely enable alarm setpoints.

The MR1 will annunciate any alarm transmitted by the Environmental controls. Table 4 catalogs the available alarms by microprocessor level.

MR1 specifications

The Liebert MR1 is a state-of-the-art precision cooling unit specifically designed for data centers and critical IT environments. It is engineered to provide optimal temperature and humidity control, ensuring the reliability and longevity of IT equipment. The Liebert MR1 stands out due to its advanced features, technologies, and characteristics, which cater to the growing demands of modern data centers.

One of the main features of the Liebert MR1 is its modular design. This modularity allows for scalable cooling solutions, providing flexibility to adapt to changing needs. The units can be easily combined to create a system that fits the exact requirements of the facility, accommodating both current and future cooling demands.

The Liebert MR1 employs cutting-edge inverter technology, which enhances the efficiency of the cooling process. This technology enables the compressor to adjust its speed, optimizing energy consumption based on real-time cooling requirements. As a result, the unit can significantly reduce operational costs while also contributing to a more sustainable environment.

Furthermore, the Liebert MR1 is equipped with advanced control systems that allow for precise monitoring and management of temperature and humidity levels. Users can easily interface with the unit through an intuitive digital display, enabling seamless adjustments and setting customized environmental parameters. This level of control is crucial for maintaining the ideal conditions conducive to equipment performance.

Another notable characteristic of the Liebert MR1 is its redundancy features. These include built-in redundancies that ensure continuous operation even in the case of a failure in one unit. This reliability is vital for data centers where uptime is of utmost importance, as any downtime can result in significant financial loss and reputational damage.

In addition to its technical features, the Liebert MR1 is designed for near-silent operation. This makes it an excellent choice for environments where noise levels need to be kept to a minimum, such as in office spaces or critical control rooms.

In summary, the Liebert MR1 is an innovative cooling solution that delivers efficiency, reliability, and flexibility for modern data centers. With its modular design, inverter technology, advanced controls, redundancy features, and quiet operation, it addresses the critical cooling requirements of IT professionals, ensuring that their systems remain operational and effective in any condition.
