This radiator is a KTX 4 Blue element - smartphone-controlled, fully thermostatic element and a round clock face style head in matching silver. Full operational control on smartphone/tablet via Bluetooth, with a choice of internal temp (30°c to 60°c) or ambient room temp (15°c to 30°c) regulation. 7-Day timer functionality. Also includes a 2-hour drying function whereby the radiator will turn off automatically when time has elapsed. The colour has a matt, rough texture. This type of colour/finish is unique for electric radiators. The element probe is pre-fitted inside the radiator and the square control head will be supplied separately and simply pushed onto the radiator. The square head can then be rotated to the required viewing angle.
