MILAN, ITALY – At the recently concluded MCE (Mostra Convegno Expocomfort) 2026, SunFly positioned itself at the forefront of the hydronic heating and cooling sector. The focus was clear: delivering high-performance OEM intelligent control products designed to meet the rigorous energy standards of the modern European market.
XF57834 Series Thermal Actuators: Setting New Benchmarks in HVAC Control Standardization
Post-Exhibition Insight: At MCE 2026, system integrators reached a clear consensus: the XF57834 series does more than provide a standardized physical interface—it redefines system responsiveness through an optimized startup mechanism (significantly faster than legacy models like the 57536). As a premium OEM core component, it excels in reducing after-sales maintenance costs while enhancing terminal brand stability.
Universal Voltage Compatibility for Global Markets
The XF57834 breaks single-power constraints by supporting dual-voltage integration (230V AC & 24V DC). This versatility allows OEM clients to utilize a unified solution that adapts to diverse global electrical grids and low-voltage smart home systems, streamlining international supply chain management.
Smooth & Precise Actuation Performance
Engineered with a 110N high-thrust force and a 4mm standard stroke, the actuator’s travel time is optimized to 120s–150s. This precision timing effectively eliminates water hammer effects within hydronic systems, ensuring smoother valve regulation and prolonged system lifespan.
High Durability in Harsh Operating Environments
Encased in high-strength PA6 material with an IP54 protection rating, the XF57834 maintains peak performance in ambient temperatures ranging from -5°C to 50°C. Furthermore, its ultra-low 3W operating power consumption meets the most stringent global energy efficiency and carbon reduction standards.
Seamless Integration & Rapid Assembly
Featuring the industry-standard M30*1.5 threaded connection and a pre-installed 750mm extended power cable, the XF57834 is designed for rapid installation. It ensures a seamless fit with underfloor heating manifolds and fan coil unit (FCU) terminal systems, drastically reducing labor time during onsite assembly and wiring.
XF57836 Series Thermal Actuators: Redefining Industry Benchmarks with High Efficiency & Ultra-Silent Performance
Post-Exhibition Insight: During MCE 2026, numerous OEM partners highlighted that the XF57836 series’ 3–5 minute gradual opening/closing buffer effectively eliminates the risk of water hammer within hydronic systems. This technical feature is critical for extending the operational lifespan of the entire HVAC piping infrastructure.
Ultra-Silent & Energy-Efficient Actuation
Utilizing advanced thermal expansion principles, the XF57836 ensures completely silent operation during valve transitions. This makes it the premier choice for high-end residential and premium office environments where acoustic comfort is paramount. Additionally, the integrated automatic spring-return function enhances system safety while significantly reducing standby energy consumption.
Standardized High-Thrust Performance
The XF57836 delivers a consistent 110N thrust force and a 4mm standard stroke, providing precise control for underfloor heating manifolds and central AC water system valves. With a mainstream 230V AC working voltage and an ultra-low 3.5VA power rating, it stands as the ideal core component for modern energy-saving HVAC systems.
OEM-Centric Installation & Safety Design
To optimize factory assembly and onsite installation efficiency, the actuator features a standard M30×1.5 threaded nut, enabling tool-free rapid mounting. A standout feature is the "Red Snap" (Anti-trigger safety pin) design: it secures the device during transit and simplifies commissioning through a "pull-to-activate" logic, drastically lowering the technical threshold for end-users.
Flexible Logic Integration for System Compatibility
To meet diverse OEM control logic requirements, the XF57836 is available in both Normally Closed (NC) and Normally Open (NO) versions. This flexibility ensures seamless integration with various smart thermostats and centralized wiring centers, allowing for a "plug-and-play" experience in complex hydronic networks.
XF58625 Series Smart Thermostats: Defining Precision & Versatility in HVAC Control
Post-Exhibition Insight: During MCE 2026, the most acclaimed feature among system integrators was the 0-10V programmable output, specifically engineered for Variable Frequency Fan (EC Fan) modulation. This technical edge positions the XF58625 as a premium solution for high-end Fan Coil Unit (FCU) applications.
Advanced Fan Control Logic & Precision Tuning
The XF58625 allows for meticulous calibration of low, medium, and high fan speeds via advanced settings (AB, AC, AD), covering an output range from 0.5V to 10V.
Solving Engineering Pain Points: This design enables installers to eliminate operational noise or airflow insufficiencies by matching the exact voltage requirements of different FCU brands. From a wholesaler’s perspective, this universal compatibility significantly reduces inventory pressure (SKU reduction).
System Flexibility & Multi-Sensor Intelligence
Dual-System Switching: Seamlessly toggle between 2-pipe and 4-pipe systems via parameter A7, making it a "one-size-fits-all" controller for diverse HVAC infrastructures.
Intelligent Sensor Modes: Supports N1 (Internal), N2 (External), and N3 (Dual-sensor) modes. In N3 mode, the external probe provides precise floor overheat protection (default 38°C), while the internal sensor maintains ambient room comfort.
High-Accuracy Climate Control: Utilizing NTC (10k) 1% high-precision sensors, the unit achieves a control accuracy of ±0.5°C, ensuring a constant and comfortable indoor environment.
BMS Integration & Commercial Scalability
The built-in Modbus RTU communication capability is the core competitive advantage for entering Commercial Building Management Systems (BMS).
Flexible Networking: Define device addresses (B1) and baud rates (B2: 2400/4800/9600) with ease, allowing for rapid deployment in large-scale networked environments.
Remote Energy Optimization: Feature A5 enables Fan-to-Valve Synchronous Control (fan shuts off when the valve closes), providing building managers with a powerful tool for energy conservation and carbon footprint reduction.
User-Centric Programming & Safety
Dynamic Scheduling: Compatible with 5+2, 6+1, and 7-day programming schemes, supporting 4 independent time periods per day to suit diverse office or residential routines.
Comprehensive Protection: Features self-diagnostic error codes (E1/E2 for sensor faults) and environment out-of-range alerts (HI/LO).
Detailed Refinements: Includes multi-level Child Locks (A2) and adjustable Standby Brightness (AA), reflecting a deep insight into the end-user’s daily comfort and safety.
International Validation of Full Industrial Chain Capabilities
This exhibition served as more than just a product showcase; it was a rigorous international validation of SunFly’s full industrial chain capabilities. Our expertise converges at the intersection of European technical heritage and China’s advanced manufacturing and service strengths—spanning from the independent R&D of core components to the delivery of integrated system solutions and continuous after-sales responsiveness.
