CTC EcoZenith i250 L/H


The CTC EcoZenith i250 is an evolution of our CTC EcoEl workhorse, which is now more efficient and features a touchscreen.

The 4.3-inch touchscreen has clear symbols with Swedish text, which makes it easy to adjust the heating and hot water or to obtain information about operation.
