Product Overview
The AC603 Underfloor model combines WiFi connectivity, weekly programmable scheduling, and a modern square design into one versatile floor heating thermostat. Built on the same platform as Telin’s popular FCU thermostat series, it has been re-engineered specifically for underfloor heating — with optimized sensor logic that accounts for thermal mass and delivers steady, comfortable radiant warmth without temperature overshoot.
At $8-14 per unit, the AC603 bridges smart home connectivity with floor heating performance. Full OEM/ODM customization available including logo branding, custom color shells, and firmware adaptations for specific heating system requirements.
Product Features
📱 Always-Connected Control
Built-in WiFi connects directly to your home network. Use the Tuya or Smart Life APP to adjust temperature, create schedules, monitor energy usage, and receive alerts — whether you’re at home, at work, or on vacation halfway around the world.
📅 7-Day Intelligent Scheduling
Set different temperature programs for each day of the week with up to 6 time slots per day. The AC603 automatically adjusts floor heating based on your schedule — warm floors in the morning, energy-saving mode while you’re away, cozy evenings exactly when you return.
▢ Modern Architectural Design
The clean square profile with minimalist aesthetics was designed to complement contemporary interiors. Available in standard white with OEM color customization for brand-specific projects — from luxury residences to boutique hospitality developments.
💡 Proven Energy Efficiency
Smart ECO mode and optimized heating algorithms deliver measurable energy savings. The AC603 learns from your heating patterns and automatically adjusts to reduce consumption during low-demand periods — typical savings of 15-25% on annual heating costs.
