Basic Specifications & Appearance Design

• Product Series:ABB i-bus® KNX PEONIA Series Smart Fan Switch Module
• Model:PESF/235.10.1-001
• Color & Finish:Matt White, adopting high-quality frosted matte technology, with non-reflective, fingerprint-resistant and easy-to-wipe surface. It is compatible with various indoor decoration styles such as modern minimalist, Nordic, light luxury and industrial, fits closely with embedded wall installation, and has excellent visual integration effect.
• Button Design:2-gang rocker switch with built-in exclusive fan icon, high visual recognition, which can quickly distinguish fan control from other device control scenes; the button stroke is specially optimized, with crisp touch and sensitive feedback, and the edge is rounded and polished, balancing use safety and operation feel, adapting to daily high-frequency pressing to adjust gears.
• Installation:Flush mounting, compatible with standard 86-type smart back box (installation depth ≥32mm, suitable for thinner back boxes, different from other models in the same series). The body is compact and thin, greatly saving wall and distribution box space, and can be seamlessly combined with other PEONIA series smart panels, adapting to multi-device linkage control scenarios.
• Protection Rating:IP20, designed specifically for dry indoor environments, suitable for non-humid areas such as living rooms, bedrooms, studies, offices and exhibition halls, avoiding the impact of humid environments on fan speed regulation performance and equipment life.
• Material:High-weather resistance and high-strength engineering plastic, with excellent scratch-resistant, anti-yellowing and anti-aging performance, which can maintain its original matte texture after long-term use, with a service life of more than 10 years, adapting to high-frequency use needs of household and commercial scenarios.

2. Core Functional Parameters

• Communication Protocol:Natively supports KNX (TP) intelligent building control bus protocol, perfectly compatible with ABB i-bus® KNX smart control system, and can be seamlessly integrated into whole-house smart and building automation networks to achieve multi-speed fan control, centralized control and remote linkage.
• Core Function:Both 2-gang buttons support multi-speed smart fan control, which can be programmed independently without mutual interference. Each button supports dual functions of fan on/off and multi-speed regulation (3-5 gears adjustable, gears can be customized through programming), and also compatible with three control modes: single control, group control and scene linkage, adapting to diverse fan use needs.
• Operation Logic:Supports dual-logic programming of short press (switch fan on/off/adjust speed gears) and long press (lock current gear/quickly adjust to maximum/minimum gear). The number of gears, speed adjustment interval and operation logic can be flexibly set through KNX ETS software, adapting to different usage habits of different groups of people and fan types.
• Backlight:The button has a built-in soft LED backlight, which can clearly identify fan icons and button positions without additional light sources at night. The backlight brightness can be manually adjusted to avoid glare, balancing the convenience of night operation and use comfort, and the backlight on/off logic can be set through programming.
• Linkage Compatibility:It can be linked with KNX switch actuators, scene control panels, smart thermostats and curtain controllers to realize scene-based control (such as "Summer Mode" automatically turning on the fan and adjusting to medium wind speed, "Away Mode" automatically turning off the fan, "Sleep Mode" adjusting to low wind speed and timing off).
• Programmability:Full programming support via KNX ETS software, which can flexibly customize button functions, gear parameters and linkage trigger conditions. The programming logic can be modified at any time according to usage needs without disassembling the device, making maintenance convenient and efficient, reducing later operation and maintenance costs.

3. Electrical & Environmental Parameters

• Power Supply:Powered by KNX bus (24V DC), no additional independent power supply is required, which simplifies on-site wiring process, reduces installation costs, and makes wiring neat and beautiful without affecting the wall decoration effect, adapting to the simple needs of embedded installation.
• Operating Temperature:-5℃ ~ 45℃, suitable for most indoor environments, including winter heating in the north and high-temperature environments in the south in summer. There is no impact from condensed water, the equipment operates stably, the fan speed regulation performance is not affected by temperature changes, and the gear adjustment is accurate without freezes.
• Mechanical Life:Button operation life ≥ 100,000 presses, fan control module service life ≥ 50,000 times, far exceeding the needs of daily high-frequency use, with strong durability, which can reduce the frequency of later device replacement and operation and maintenance costs, adapting to high-frequency commercial use scenarios.
• EMC:Complies with industrial-grade Electromagnetic Compatibility (EMC) standards, with strong anti-electromagnetic interference ability, which can resist interference from electrical equipment and network signals in buildings, ensuring accurate transmission of fan control commands, stable operation without freezes, false triggers or gear jumps.
• Load Compatibility:Compatible with various KNX protocol smart fans, with a wide load compatibility range (supporting 10-100W fan load), which can meet the multi-speed control needs of fans with different powers and types, adapting to household ceiling fans, table fans and commercial small fan scenarios.

4. Core Application Scenarios

• Smart Home Scenarios:Living rooms, bedrooms and studies in villas, large apartments and high-end residences, adapting to household smart ceiling fan and table fan control. Multi-speed regulation can meet different needs such as reading, resting and daily activities. The matt white embedded appearance fits closely with the wall, enhancing the home style.
• Commercial Office Scenarios:Grade A office buildings, premium offices, meeting rooms and reception rooms, which can centrally control or independently control fan operation and gear adjustment, adjust appropriate wind speed according to office scene needs, improve office comfort and work efficiency, and embedded installation fits the simple decoration needs of office spaces.
• Commercial Leisure Scenarios:Boutique hotel guest rooms, light luxury homestays, cafes and small exhibition halls. Fan gears are controlled through scene linkage to create a comfortable space atmosphere. Multi-speed adapts to the needs of different groups of people. The matt white appearance is simple and elegant, fitting the decoration needs of high-end commercial spaces.
• Public Building Scenarios:School libraries, cultural centers, community service centers and small office areas. Fan operation and gears can be controlled according to usage scenarios, adapting to the needs of multiple people in public areas. The buttons have clear identifiers and are easy to operate, durable and easy to maintain, reducing the operation and maintenance costs of public areas.
