The KT2000 is a Ketotek digital plug-in thermostat outlet for 230 V EU sockets. It uses an external waterproof temperature probe and supports heating or cooling modes via an internal relay. Features include high/low temperature alarms, temperature calibration, and a selectable backlight timer. The controller switches connected equipment on/off (non‑dimming), and can operate devices such as heaters or fans. The temperature control range is approximately −50 to 110 °C, with a maximum resistive load around 16 A/2300 W at 230 V. This single‑channel unit is a simple way to automate environmental temperature without humidity control or Wi‑Fi.
