Smart HVAC for Schools and Offices: Solving Energy Challenges with LoRaWAN TRV

Energy efficiency in large-scale facilities is often hindered by the complexity of the environment. From university dormitories where windows are left open, to commercial offices with uneven heating, each sector faces unique hurdles. In this post, we explore how the SEA889 LoRaWAN TRV provides tailored solutions for three high-impact scenarios.

LoRaWAN vs Zigbee for Commercial HVAC: Why LoRaWAN is Superior for Large Buildings

For system integrators (SIs) and facility engineers planning a smart building energy retrofit, selecting the right wireless protocol is the most critical technical decision. While Zigbee is a household name in home automation, LoRaWAN has emerged as the industrial gold standard for large-scale commercial HVAC control.

Commercial LoRaWAN TRV ROI: Why Battery Life is the #1 Factor in Heating Retrofits

When energy managers and sustainability directors at universities, hospitals, or social housing associations embark on a commercial energy-saving retrofit, the focus is often misplaced on the initial capital expenditure (CAPEX). They ask: "What is the unit cost of the radiator valve?"

BACS Compliant LoRaWAN TRV: A Guide to Meeting EN 15232 Standards

As the 2025 deadline for global energy efficiency mandates approaches, the BACS (Building Automation and Control Systems) directive—specifically EN 15232—has moved from a recommendation to a strict requirement for large commercial buildings. For property owners and engineers, the challenge lies in achieving high-level automation in existing structures. This is where the BACS compliant LoRaWAN TRV becomes an essential tool for modern energy management.

Sharing Christmas Joy Across Borders

As the holiday season approaches, we took a moment to celebrate Christmas together at the office — sharing joy, surprises, and meaningful connections with our colleagues and international partners.

Active ΔT Control vs. 0–10V Modulating Actuators in Hydronic Underfloor Heating Systems

In hydronic HVAC control, the term “modulating” can describe very different control philosophies. Understanding the difference between passive response and active intelligence is essential when evaluating modern B2B solutions.

Eliminating UFH Hot and Cold Spots: How Saswell SA905-T Ensures Uniform Heat Distribution

Underfloor heating (UFH) is marketed as the ultimate luxury, yet many homeowners suffer from hot and cold spots—where one room is freezing while another feels like a sauna. This isn't necessarily a boiler or pump issue; it is a hydronic imbalance problem. In this article, we’ll analyze why water fails to distribute heat evenly and how the Saswell SA905-T Stepper Motor Actuator provides the definitive solution through real-time ΔT balancing.

Why a Stepper Motor is Better Than a Wax Element Actuator for ±1.5℃ UFH Control?

For modern, high-efficiency hydronic systems, the actuator is the final bridge between smart control and real-world comfort. While traditional wax element actuators have been the industry standard for decades, the Saswell SA905-T Stepper Motor Actuator is redefining the performance ceiling of Underfloor Heating (UFH).
