4.5.2 Indoor heat exchanger anti-overheated

When indoor exchanger temperature is higher than 50℃, the compressor frequency will be lowered down to protect the heat exchanger. When indoor exchanger temperature lower down to 46℃, the compressor frequency rise up, and when the indoor exchanger temperature lower to 44 ℃ and keep for 5 minutes, and compressor frequency will rise to former value.

When condenser temperature is higher than 54℃, the compressor will stop, and hen the condenser temperature lower to 44℃ and keep for 5 minutes, and compressor frequency will rise to former value

4.6 Emergency Operation

The set temperature is 24, and the fan speed is AUTO during emergency operation.

Press emergency switch within 5 s during stand-by mode, and the air conditioner starts emergency mode if there is DU sound from indoor unit.

KFR-25GWZ BM, KFR-25GWZ, BM specifications

The Shinco BM and KFR-25GWZ series represent a significant advancement in air conditioning technology, combining efficiency, performance, and user-centric features. Designed for both residential and small commercial applications, these models aim to provide optimal comfort while minimizing energy consumption.

One of the standout features of the Shinco BM series is its impressive energy efficiency rating, which helps to reduce electricity bills while still delivering powerful cooling and heating performance. The models are equipped with advanced inverter technology that allows for variable speed operation. This means that rather than cycling on and off entirely, the compressor adjusts its speed according to the required cooling or heating load. This not only results in a more consistent temperature but also extends the lifespan of the unit.

The KFR-25GWZ model integrates a multi-stage filtration system that ensures cleaner air quality. This system effectively captures dust, allergens, and other airborne particles, promoting a healthier indoor environment. Additionally, these units often feature a self-cleaning function which helps maintain the cleanliness of the internal components, enhancing efficiency and longevity.

User-friendly interfaces are another hallmark of the Shinco series. The remote control and optional Wi-Fi connectivity allow users to monitor and adjust settings from their smartphones or tablets. Features like programmable timers, sleep modes, and multiple fan speeds further enhance convenience.

In terms of design, the KFR-25GWZ is both sleek and modern, making it a perfect fit for various interior aesthetics. Its compact design ensures that it can be installed in a range of spaces without being obtrusive.

The noise levels of both the BM and KFR-25GWZ units are impressively low, making them suitable for bedrooms, offices, and other areas where quiet operation is essential. Enhanced insulation within the units minimizes sound, allowing users to enjoy their space without distraction.

Safety features including automatic restart after a power outage and overcurrent protection make these air conditioners reliable choices for households and businesses alike. Additionally, the environmentally friendly refrigerants used in these models contribute to lower global warming potential, aligning with contemporary sustainability goals.

In conclusion, the Shinco BM and KFR-25GWZ series showcase a blend of innovative technology, energy efficiency, and user-friendly features, making them an excellent choice for those looking to enhance their indoor comfort in a sustainable way.
