13. Protection Control

13.1 Protection Control For All Operations

13.1.1Restart Control (Time Delay Safety Control)

šThe Compressor will not turn on within 3 minutes from the moment operation stops, although the unit is turned on again by pressing OFF/ON button at remote control within this period.

šThis control is not applicable if the power supply is cut off and on again.

šThis phenomenon is to balance the pressure inside the refrigerant cycle.

13.1.2Total Running Current

1When the outdoor unit total running current (AC) exceeds X value, the frequency instructed for compressor operation will be decreased.

2If the running current does not exceed X value for 5 seconds, the frequency instructed will be increased.

3However, if total outdoor unit running current exceeds Y value, compressor will be stopped immediately for 3 minutes.

13.1.3IPM (Power transistor) Prevention Control

šOverheating Prevention Control

1When the IPM temperature rises to 248°F (120°C), compressor operation will stop immediately.

2Compressor operation restarts after 3 minutes the temperature decreases to 230°F (110°C).

3If this condition repeats continuously 4 times within 20 minutes, timer LED will be blinking (“F96” is indicated).

šDC Peak Current Control

1When electric current to IPM exceeds set value of 16.0 ±2.0A, the compressor will stop operate. Then, operation will restart after 3 minutes.

2If the set value is exceeded again more than 30 seconds after the compressor starts, the operation will restart after 1 minute.

3If the set value exceeded again within 30 seconds after the compressor starts, the operation will restart after 1 minute. If this condition repeats continuously for 7 times, all indoor and outdoor relays will be cut off, timer LED will be blinking (“F99” is indicated).

CU-XE12PKUA, CU-XE9PKUA, CS-XE9PKUA, CS-XE12PKUA specifications

The Panasonic CU-XE9PKUA, CU-XE12PKUA, CS-XE12PKUA, and CS-XE9PKUA are part of Panasonic's advanced lineup of air conditioning units, designed to deliver reliable comfort and energy efficiency in residential and commercial settings. These models are engineered with cutting-edge technology to ensure optimal performance, sustainability, and user convenience.

One of the standout features of these air conditioning units is their high energy efficiency ratings. Equipped with inverter technology, they adjust the compressor’s speed according to the temperature, maintaining the desired comfort level without unnecessary energy consumption. This not only reduces electricity bills but also ensures a smaller carbon footprint, making them an eco-friendly choice.

The CU-XE9PKUA and CU-XE12PKUA units are outdoor models, which seamlessly pair with their indoor counterparts, the CS-XE9PKUA and CS-XE12PKUA, respectively. This split system design provides versatile installation options while ensuring quiet operation. The outdoor units are built to withstand a variety of weather conditions, contributing to their durability and longevity.

In addition to their robust energy efficiency, these units feature advanced cooling and heating capabilities. With the inclusion of Panasonic’s unique “nanoe-G” technology, these models not only cool or heat the air but also purify it. Nanoe-G technology releases hydroxyl radicals that effectively eliminate harmful particles, such as bacteria and allergens, ensuring that the air you breathe is cleaner and healthier.

The design of the indoor units is sleek and modern, integrating easily into any décor. With features like quiet operation, they are perfect for bedrooms and quiet spaces, ensuring that the comfort of climate control does not come at the expense of serenity.

User convenience is further enhanced with smart control options. Many of the models come equipped with Wi-Fi connectivity, allowing users to control their air conditioning systems remotely via a smartphone app. This means adjusting temperature settings, scheduling operations, or activating modes can be done effortlessly, ensuring maximum comfort at all times.

Overall, Panasonic's CU-XE9PKUA, CU-XE12PKUA, CS-XE12PKUA, and CS-XE9PKUA models combine innovative technology, energy efficiency, and user-friendly features, making them excellent choices for anyone seeking reliable climate control solutions. Whether for residential use or commercial applications, these air conditioners promise to deliver comfort, quality, and peace of mind.
