Rated 5 out of 5 by Seems v good Replaced a twenty-year old Potterton t.stat. Quick and easy. three wires to connect. Needed no earth. Looks robust plastic and metal.. Well-designed terminals and cable clamp. I checked the set temp with an IR thermometer and it was controlling to within a degree or so of the set temp. 22 Sep 2016
