5 - PRO-DIALOG CONTROL OPERATION

5.1 - Start/stop control

The table below summarises the unit control type and stop or go status with regard to the following parameters.

-Operating type: this is selected using the start/stop button on the front of the user interface.

-Remote start/stop contacts: these contacts are used when the unit is in remote operating type (rEM). See sections 3.6.2 and 3.6.3.

-CHIL_S_S: this network command relates to the chiller start/stop when the unit is in CCN control (CCn). Vari- able forced to disable: the unit is halted. Variable forced to Enable: the unit runs in accordance with schedule 1.

-Start/Stop schedule: occupied or unoccupied status of the unit as determined by the chiller start/stop program (Schedule #1). Used when the unit is equipped with an optional CCN/clock board, otherwise the chiller occupied mode is forced to occupied all the time.

-Master control type. This parameter is used when the unit is the master unit in a two chiller lead/lag arrange- ment. The master control type determines whether the unit is to be controlled locally, remotely or through CCN (this parameter is a Service configuration).

-CCN emergency shutdown: if this CCN command is activated, it shuts the unit down whatever the active operating type.

-General alarm: the unit is totally stopped due to failure.

30RY/RYH, 30RA/RH specifications

The Carrier 30RY/RYH and 30RA/RH chiller models are leading solutions in commercial and industrial cooling applications. Renowned for their reliability, efficiency, and advanced technologies, these chillers cater to a wide variety of settings, from office buildings to manufacturing facilities.

The models are engineered to deliver substantial energy savings, meeting or exceeding the latest ASHRAE and DOE efficiency standards.

A significant aspect of the 30RY and 30RA models is their use of environmentally friendly refrigerants. The 30RYH, for instance, employs R-134a refrigerant, which is designed to minimize ozone depletion while maximizing efficiency. This commitment to sustainability aligns with modern environmental regulations and practices, making these chillers a wise choice for eco-conscious projects.

In terms of control technology, the chiller models come equipped with advanced microprocessor-based controls, providing users with optimal system management and diagnostics. This integrated control system enhances the overall performance and reliability of the chillers, allowing for real-time monitoring and adjustment to ensure peak operational efficiency.

Another key feature is the quiet operation of the 30RY/RYH and 30RA/RH series. Designed with sound attenuation in mind, these units minimize noise pollution, making them suitable for installations in noise-sensitive environments. Additionally, the modular design allows for easy installation and maintenance, reducing downtime and providing flexibility in system design.

Both series also offer robust thermal performance, with the capability to handle a wide range of operating conditions. The chillers excel in terms of cooling capacity, providing solutions for varying thermal loads while maintaining energy efficiency. This adaptability is invaluable for facilities managing seasonal changes in cooling demands.

In summary, the Carrier 30RY/RYH and 30RA/RH chillers represent an ideal blend of efficiency, advanced technology, and eco-friendliness. Their high-performance capabilities, user-friendly controls, and sustainable design make them a top choice for commercial and industrial applications, ensuring dependable cooling solutions for diverse environments.
