1. Basic Specifications & Appearance Design

• Product Series:ABB i-bus® KNX PEONIA Series Smart Blind Fine Regulation Switch Module
• Model:PESJ/35.10.1-001
• Color & Finish:Matt White, adopting high-quality delicate frosted matte technology, with a non-reflective, fingerprint-resistant and easy-to-clean surface, warm texture. It is compatible with various indoor decoration styles such as modern minimalist, Nordic, light luxury and minimalist, fits closely with the wall, has excellent visual integration effect, and perfectly adapts to the decorative unity needs of the whole-house smart scene.
• Button Design:2-gang rocker switch with built-in high-definition exclusive blind icon, high visual recognition, which can quickly distinguish the fine regulation function of blinds from other smart device control scenes and avoid operation confusion; the button stroke is finely optimized, with crisp and soft touch, sensitive feedback, moderate pressing force, and the edge is rounded and polished, balancing use safety and operation feel, adapting to daily high-frequency blind fine regulation operations.
• Installation:Flush mounting, compatible with standard 86-type smart back box (installation depth ≥30mm, suitable for thinner back boxes, different from the previous two models in the same series). The body is compact and thin, saving wall and distribution box space, and can be seamlessly combined with other PEONIA series smart panels, perfectly integrating into the whole-house smart control panel combination scene, with convenient installation and no damage to the wall decoration integrity.
• Protection Rating:IP20, designed specifically for dry indoor environments, suitable for non-humid areas such as living rooms, bedrooms, studies, offices and high-end exhibition halls, avoiding the impact of humid environments on fine regulation performance, motor adaptation stability and equipment service life, and fully adapting to common blind installation scenarios.
• Material:High-weather resistance and high-strength engineering plastic with anti-aging, scratch-resistant and anti-static ingredients, with excellent scratch-resistant, anti-yellowing, anti-aging and anti-static 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 fine regulation operation needs of household and commercial scenarios, and resisting daily minor collisions.

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 blind fine regulation, centralized control and remote linkage. It also supports linkage adaptation with whole-house smart devices (voice assistants, mobile APPs, scene panels), adapting to high-end whole-house smart scenarios.
• Core Function:Both 2-gang buttons can be programmed independently without mutual interference. It mainly supports blind fine regulation (fine adjustment of opening angle and lifting height) and on/off control, and also has multi-type blind motor adaptation function, compatible with DC and AC blind motors. Each button can customize fine regulation modes (angle fine adjustment, height fine adjustment), and is also compatible with three control modes: single control, group control and whole-house smart linkage, adapting to diverse blind use needs (household window blinds, commercial curtain blinds, high-end smart blinds, etc.).
• Operation Logic:Supports dual-logic programming of short press (switch blind on/off/call preset fine regulation parameters) and long press (continuously fine-tune blind angle/lifting height, adjustable regulation precision). The regulation sensitivity, fine adjustment step value and operation logic can be flexibly set through KNX ETS software, adapting to different operation habits of different groups of people and blind types, and accurately matching daily fine lighting and privacy protection needs.
• Backlight:The button has a built-in soft LED backlight, which can clearly identify blind icons and button fine regulation functions 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. The backlight delay off and linkage on (such as automatically turning on the backlight when a person is detected approaching) functions can be set through programming, which is energy-saving and intelligent.
• Linkage Compatibility:It focuses on supporting whole-house smart linkage, and can be linked with KNX switch actuators, scene control panels, smart thermostats, light sensors, voice assistants and mobile APPs to realize intelligent scene-based fine regulation (such as "Lighting Fine Adjustment Mode" automatically fine-tuning the blind angle according to light intensity, "Voice Control Mode" realizing blind fine regulation through voice commands, "Away Linkage Mode" automatically closing the blinds and resetting to the preset state), improving use convenience and intelligent experience.
• Programmability:Full programming support via KNX ETS software, which can flexibly customize button functions, blind fine regulation parameters, whole-house smart linkage trigger conditions and motor adaptation parameters. 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. It also supports firmware upgrade to expand more smart linkage functions.

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. At the same time, stable power supply ensures the smooth operation of fine regulation and smart linkage functions.
• 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 blind fine regulation performance and motor adaptation stability are not affected by temperature changes, and the angle and lifting adjustment are stable without freezes or deviations.
• Mechanical Life:Button operation life ≥ 100,000 presses, blind fine regulation 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 fine regulation scenarios.
• EMC:Complies with industrial-grade Electromagnetic Compatibility (EMC) standards, with strong anti-electromagnetic interference ability, which can resist interference from electrical equipment, network signals and whole-house smart device signals in buildings, ensuring accurate transmission of blind fine regulation commands and smart linkage commands, stable operation without freezes, false triggers or regulation deviations.
• Load Compatibility:It focuses on optimizing the adaptation performance of multi-type blind motors, compatible with various KNX protocol smart blind motors (DC/AC), with a wide load compatibility range (supporting 30-180W blind motor load), which can meet the fine regulation needs of blinds of different types and powers, adapting to various scenarios such as household, commercial and high-end smart, with more stable motor operation and more accurate regulation.
• Control Precision:The precision of angle fine regulation ≤0.3%, and the precision of lifting fine regulation ≤0.5cm, which can realize micro-adjustment of blind angle and lifting height, accurately adapting to different lighting and privacy needs. The regulation precision is far higher than the previous two models in the same series, highlighting the core advantages of this model.
