Application
The wireless intelligent one-to-one digital thermostat is a temperature controller suitable for underfloor heating systems. By comparing the ambient temperature with the set temperature, the working status of the gas wall mounted boiler and electric valve in the underfloor heating system is controlled to achieve the goals of regulating the ambient temperature, comfort, and energy conservation.
