EST-150 smart thermostat solution consists of 2 elements, connected by a quick faston connection cable.
The first element is the electronic functional capillary type thermostat. It controls the heater and collects data about water temperature.
The second element is electronics with LCD TFT display 1.44'', 4 buttons, user interface, and Wi-Fi module. Collected data from the first element is being processed in the second one.
Mobile applications, as part of EST-150 solution, provide the complete product functionality. The conventional mechanical safety capillary type thermostat should be used additionally as a safety component in the water heater.
