ZLLP-M1-21-279-T Air Conditioning Fresh Air Energy Saving Controller

Overview of Integrated Building Equipment Monitoring System

The Integrated Building Equipment Monitoring System complies with the requirements of Section 18.14 of the national standard GB51348-2019 "Standard for Electrical Design of Civil Buildings." It enables building equipment monitoring, power monitoring, lighting control, residual current monitoring, energy metering, environmental monitoring, energy efficiency management, and other building monitoring and management functions. The system includes equipment for the distribution, conversion, protection, control, metering, and safety of electrical energy, as well as monitoring, metering, control, and protection functions for controlled equipment. It also provides human-machine control operations, information and status display, and network communication capabilities. The system interconnects building equipment control systems via networks to form a comprehensive and integrated power supply, monitoring, and control system.

Intelligent Low-Voltage Complete Control Equipment Complies with the Latest Relevant Standards

Resolution TC06-2021-06 regarding the mandatory product certification standard for intelligent low-voltage switchgear, which replaces GB/T 7251.8-2005 with GB/T 7251.8-2020.

GB/T 7251.8-2005 has been replaced by GB/T 7251.8-2020 "Low-voltage switchgear and controlgear assemblies – Part 8: General requirements for intelligent assemblies." The new standard was issued on November 19, 2020, and came into effect on June 1, 2021.

After the replacement, the certification standard for low-voltage intelligent complete equipment originally based on GB/T 7251.8-2005 has been changed to GB/T 7251.8-2020. I. Differences Between the Old and New Standards

GB/T 7251.8-2020 differs from GB/T 7251.8-2005 in terms of standard structure, technical content, verification items, and testing methods.
