As a professional installer, i use to use these controlers.
I had two of them stop working within a year. When I called Luis, the owner of the company, he refused to honor he warentee. He said that his product never malfunctioned and didnt want to see my two dead controlers.
If you want to see temperatures I recomend the stecca. It has temperature read outs and a holiday function that will dump heat through the collectors at night. If you want even more controll over the system, buy a resol (sunmaxx)
