The GKW-01 is a modern temperature controller designed to control underfloor heating or other heating systems. It allows you to set the temperature using touch buttons on the housing or remotely using the Supla app. The Wi-Fi temperature controller is equipped with an LED matrix display with automatic brightness adjustment. The GKW-01 also has a 16A voltage-free relay output that can control electric heaters or valves. The device has a built-in clock, allowing it to follow a preset weekly program regardless of internet connection availability. The Wi-Fi temperature controller can connect an external sensor (e.g., a window opening sensor, an NTC temperature sensor, a hotel card reader), with the option of programming an action (e.g., turning off the thermostat).
