Product information

Description

Avatto WT100 smart thermostat for water heaters with Wi‑Fi and 3 A output. The WT100 is designed to control water heating systems in homes and small offices, providing precise temperature regulation via an NTC sensor with 1°C accuracy.

Advantages

The thermostat offers programmable weekly schedules (5+2, 6+1 or 7 days) with up to 6 time periods per day, manual and automatic operation modes, and a built‑in LCD that shows current mode, set temperature, network status and time. It supports touchscreen control, app control, and voice control. Additional features include a child lock, grouping of multiple devices and the ability to share access with other household members.

You can also control the thermostat via its touchscreen or by voice commands after enabling the chosen voice assistant integration.

Usage recommendations

For reliable operation, install the thermostat in a dry, well‑ventilated location away from direct heat sources. Use the app schedules to optimise energy consumption and enable the child lock if the device is accessible to children. Do not exceed the 3 A maximum load rating; for higher power heaters use an appropriate external relay or contactor.
