SONOFF TP-WGZBA Zigbee Smart Thermostat – Water Floor Heating & Boiler Control, 3 Heating Schedules, Dial Control, Window-Open Detection (Zigbee Hub Required)

Heat your home with more comfort and less waste. The SONOFF TP-WGZBA is a Zigbee smart thermostat panel for hydronic (water) heating systems and boilers. It offers both a powered relay output (up to 3A) and a potential-free dry-contact output (COM and NO terminals), so it can suit many different heating setups. 🔥🏠✨

A smooth physical dial gives you simple temperature control from 5°C to 30°C, while built-in human presence sensing wakes the display as you approach and turns it off when you leave. Create three independent heating plans, each with a full-week schedule and up to 12 time periods per day, and switch easily between weekday, weekend, and holiday routines.

⚠️ Important Note
A Zigbee hub or gateway is required, and it is sold separately. This thermostat is designed for water heating systems and boilers, and handles resistive loads only. It is not for electric heating loads above 3A, and it is not suitable for every system, so please check your heating type, wiring, and boiler control terminals before ordering. Installation by a qualified electrician or heating engineer is strongly recommended. ✅🔌
