Overview
The Y819H/16 WiFi Thermostat is a wall room controller for electric heating and carbon film systems: tactile buttons on the panel for daily use, plus remote WiFi operation from Android or iPhone for schedule changes and monitoring. Widely deployed in hotels, hospitals, schools and office buildings, it keeps each room at a chosen setpoint and lets facility staff adjust rooms remotely without walking floors. It is part of our thermostats & controls range.
It pairs with electric heating mats and graphene heating film rooms. For the smaller residential sibling, compare the Y603H WiFi thermostat; for touch-screen UI, see the E91.716 touch thermostat.
Key Features
- Two ways to control — direct buttons on the panel and remote WiFi operation from Android / iPhone.
- Electric & carbon film control — built for electric underfloor heating and carbon film heating systems.
- Mode selection on panel — set target temperature, pick operating mode, and switch schedules without opening the app.
- Built for public buildings — proven in hotels, hospitals, schools and office buildings.
- Wide voltage supply — 90–260 V~ 50/60 Hz covers 110–120 V and 220–240 V markets.
- 3 m NTC floor sensor — floor-temperature protection for wood and carpet finishes.
- Flame-retardant PC + ABS body — durable, modern fascia for high-traffic corridors.
- Grouped app control — manage many rooms from one dashboard.

Wiring & Installation
Mount on a standard recessed wall back box. Feed mains to L/N terminals; the load output switches the electric heating or carbon film circuit. Route the 3 m floor sensor under the floor finish and into the sensing input. Pair with the app over 2.4 GHz WiFi following the standard wizard; the on-panel buttons remain fully functional offline. For circuits above the rated load, drive a contactor from the thermostat output. Use an RCD-protected supply and have the final wiring commissioned by a qualified electrician.
Compatible Heating Systems
- Electric heating mats — tiled guest rooms and public areas.
- Graphene / carbon heating film — thin film rooms and suspended floors.
- Heating cables — looped bathroom and lobby zones.
- Hotel floor heating mat — multi-room hospitality programmes.
- Underfloor heating systems — building zoning design.
WiFi App & Remote Control
Staff and owners use the Android/iOS app to set temperatures, choose modes and adjust schedules room by room or floor by floor — pre-warm hotel rooms before arrivals, set back school zones at night, and monitor status remotely. Each panel is also fully operable by buttons, so guests, patients and students are never locked out. Rooms group into one dashboard, which is why it suits chain properties and multi-floor buildings.
Safety & Certifications
Flame-retardant PC+ABS enclosure with 100 % factory testing, certified CE and RoHS under ISO 9001 production management. The floor sensor enforces safe floor temperatures under finish materials; child/guest lock protects programmed settings in public rooms; freeze-protection mode keeps empty buildings safe through winter. RCD-protected installation completes the safety chain.

FAQ
Can staff control rooms remotely without an app on-site?
Yes — the Y819H supports remote WiFi operation from Android or iPhone: temperatures, modes and schedules can be changed and monitored from one dashboard for the whole building, while the on-panel buttons still work locally.
Which heating systems does it control?
It is designed for electric underfloor heating systems and carbon film heating systems — setting temperature, choosing mode and running schedules across rooms.
Is it suitable for hotel and hospital projects?
Yes — this model is widely used in hotels, hospitals, schools and office buildings, with guest lock, grouped app management and durable public-building hardware.
Does it work on both 110 V and 230 V systems?
The wide 90–260 V~ 50/60 Hz supply covers 110–120 V and 220–240 V installations, so one model fits multi-country project tenders.
What is the warranty?
2 years, including online technical support, free spare parts and return/replacement service. Project contracts can extend cover and add commissioning support.
