Nobo NTB-2T is a combined room and floor heating thermostat in white, with a built-in weekly timer programmed directly on the unit. It works from the integrated room sensor or from the supplied external floor sensor, and can also be used as a power regulator. The measuring range is 7 to 40 deg C on a 230 V AC supply, using on/off control with PID regulation. The backlit display shows system status by colour: red for comfort, green for energy saving and blue for frost protection. The housing measures 86 x 86 x 44 mm. Typical applications include electric underfloor heating in bathrooms, hallways and living areas, and panel-heater circuits that need timed setback. Producer number 86000103.
