Terma heating elements like MEG, MOA and their KTX range will remember last settings used. Even if the power supply is cut off. These are microchip based products. Heating is electronically controlled. Some devices offer more than just a temperature control. MOA is a neat, small device with 2hrs booster/timer. KTX3 offers simple daily timer and dryer function. KTX4 has an infrared functionality allowing you to control heating element via external infrared controller (flexible programmes).
