MICROPROCESSOR CONTROLLER

The following pages contain a brief overview of the optional cassette microprocessor control system and its components. The Infra-Red Remote Control manual is available from the unit manufacturer and provides a more comprehensive ex- planation of the operation and application of the Cassette microprocessor control system.

The microprocessor controller has built-in software to limit the number of starts per hour. This operates by having a minimum period of ten minutes between consecutive starts. A four minute delay period between the compressor stop-

ping and starting is also included to allow refrigerant pres- sures to equalize between high and low sides during the compressor off period.

IMPORTANT: Before applying main power to the unit, please ensure jumper link “JMP2” is in the correct position. JMP2 should be open for DX Non-Heat Pump or Chilled Water systems and closed for Heat Pump systems. (A jumper link settings guide can be found on the Cassette unit’s wiring schematic).

INFRARED RECEIVER & FASCIA DISPLAY PANEL

The infrared receiver is an extension of the control board and is located on the fascia of the unit, connected by a 7 pin plug and socket.

The green On/Off indicator will remain lit when the unit is running or will flash if heating or cooling is required but the compressor anti-cycle timer is delaying compressor opera- tion.

Yellow indicators will illuminate to show when the unit is in “cool” or “heat” mode. These indicators will flash when the battery on the main circuit board requires changing.

The red indicator will be lit when the in-built time clock func- tion is activated. To disable the time clock, all start/stop times must be set to 12am via the transmitter (see program- ming instructions in this installation manual). The red indi- cator is also used to diagnose operational alarms.

SELF DIAGNOSTICS: The microprocessor controller has a built-in diagnostics feature so that, in the event of an alarm, the nature of the fault can be determined. The red timer/ alarm LED flashes on the fascia in a pre-determined fre- quency depending on the fault. These are identified below:

1.Red Timer/Alarm flashes once every second - in- door coil sensor failure, low coil temperature or condensate high level trip.

2.Red Timer/Alarm flashes once every 5 seconds - return air sensor failure.

Refer to the Troubleshooting section of this manual for further instruction on dealing with alarms.

WLCA specifications

EMI WLCA, or Electromagnetic Interference Wireless Lightning Control Architecture, represents a groundbreaking evolution in the realm of electromagnetic interference mitigation technologies. Designed to safeguard sensitive electronic systems from the potentially detrimental effects of electromagnetic disturbances, EMI WLCA integrates a host of advanced features and characteristics that empower both industries and consumers.

One of the primary features of EMI WLCA is its ability to operate across various frequencies. This versatility ensures that it can mitigate interference from a wide range of sources, whether they originate from industrial machinery, communication devices, or environmental factors. By effectively filtering out these unwanted signals, the technology facilitates more stable and reliable performance in electronic systems.

At the heart of EMI WLCA lie several state-of-the-art technologies that enhance its efficiency. Adaptive filtering is a key component, allowing the system to dynamically adjust its response based on the detected interference levels. This real-time adjustment capability ensures optimal performance, minimizing lag and improving responsiveness in critical applications, such as aviation, telecommunications, and medical devices.

Another notable characteristic of EMI WLCA is its modular design. This allows for easy integration into existing systems, enabling manufacturers to incorporate the technology without necessitating an overhaul of their current infrastructure. The modularity also facilitates future upgrades, ensuring that systems can adapt to changing standards and emerging interferences.

In addition to its impressive technical specifications, EMI WLCA is designed with user-friendliness in mind. Comprehensive monitoring tools provide users with insightful data on interference levels and the effectiveness of the mitigation strategies being employed. This transparency not only aids in troubleshooting but also enhances overall system performance by allowing users to make informed adjustments as needed.

Moreover, EMI WLCA is built to meet stringent regulatory compliance standards. This ensures its broad applicability across various sectors, including aerospace, automotive, and consumer electronics. As technology continues to advance, the RF environment becomes increasingly crowded, making solutions like EMI WLCA not only desirable but essential.

In conclusion, EMI WLCA stands out as a significant advancement in electromagnetic interference control technology. With its adaptive filtering capabilities, modular design, user-friendly monitoring tools, and compliance with industry regulations, EMI WLCA promises to enhance the reliability and performance of electronic systems across diverse applications. As the demand for interference-resistant technology grows, innovations like EMI WLCA will undoubtedly play a critical role in shaping the future of electronic design and implementation.
