The build feels robust and ready for long-term installation, featuring clean terminal blocks that simplify the wiring process. It handles both 24V and 220V power inputs reliably, showing a high level of versatility in its hardware engineering.
Day-to-Day Experience
Integrating this device via WiFi allowed for seamless schedule adjustments right from my smartphone. The Modbus RTU protocol makes it a perfect candidate for those looking to hook their thermostat into a broader building automation network.
This is an excellent choice for DIY smart home enthusiasts and professionals looking for a reliable, protocol-compliant solution for fan coil units.
