The HT-70 is a premium 220V wall-mounted smart WiFi thermostat meticulously engineered for water radiant floor heating and gas boiler systems. By combining advanced 7-day programmable scheduling with seamless remote app control, it delivers the ultimate balance of energy efficiency and home comfort for modern residential and commercial spaces.
Equipped with a specialized 3A relay, the HT-70 is purposefully built for hydronic (water-based) heating systems. It reliably controls normally open (NO) / normally closed (NC) thermal actuators, motorized valves, and gas boilers with volt-free output. Unlike generic thermostats, its precise algorithms prevent the system from overshooting, ensuring your radiant floors maintain a consistent and comfortable temperature without wasting energy.
As a top-tier programmable thermostat, the HT-70 empowers users to set automated 7-day / 4-period heating schedules according to their habits. The mobile APP allows remote one-key control, enabling you to switch conventional heating systems on and off remotely at any time, anywhere. Easily switch between Manual, Economy, and Programmable (PRG) modes.
Ultra-high-precision temperature control brings you the ultimate enjoyment. Built-in 2.4GHz WiFi allows effortless remote management via the Tuya Smart or Smart Life mobile applications. Additionally, it seamlessly connects with Amazon Alexa and Google Assistant, bringing you a more comfortable and convenient life through remote voice control.
Workable for gas boilers with volt-free output or electrovalves with 230Vac output. Below is the standard wiring configuration for safe and accurate installation:

A: No. This specific HT-70 model features a 3A relay and is strictly designed for water radiant heating and gas boilers. However, we manufacture an identical-looking version equipped with a robust 16A relay specifically designed to safely handle the high electrical load of electric heating mats and cables. If your project requires electric floor heating, please contact our sales team directly to request the 16A model.
A: Yes. To power the smart LED display and maintain a stable 2.4GHz WiFi connection, the thermostat requires a standard 220V AC hardwired connection, which means both a Live (L) and Neutral (N) wire must be present in your wall box.
A: Yes, the thermostat supports versatile wiring setups and can accurately control both NO and NC thermal actuators or motorized valves used in water underfloor heating manifolds.
A: For water-based radiant heating, the built-in ambient air sensor is usually sufficient to maintain room comfort. However, the unit does support an optional external NTC 10K floor sensor, which is highly recommended if you need precise floor temperature limiting to protect sensitive flooring materials like wood or vinyl.
A: By utilizing the 7-day / 4-period scheduling, the thermostat ensures your boiler or valves only run when necessary. You can program lower temperatures during sleeping or working hours and have the system pre-heat right before you wake up or return home, cutting down unnecessary boiler runtime.
