I have in my kitchen a compartment with a hinged door upwards. The old microwave had a lot of space in it. My new combi boiler (Microwave, Top / bottom heat, grill and convection) requires almost the entire width and height. (Well, so 4-5 cm around it) With prolonged use, the heat accumulates in it. Free in the kitchen I do not ask what I have this convenient compartment on the chest the device. (As my oven) With a fan, I prefer from the air and blow behind the cabinet upwards. This regulator I use in the cooling mode, if 45 ° or warmer, fan and at 30 ° C again. The parameters can be changed very easily. (Hysteresis, temperature correction, etc.). The target temperature you can be called with one touch and easy to adjust with the up / down keys. Very well made, optically correct and easy to read display. Once I must somehow regulate temperature again, I order the same control again.
