Hi All,
I wonder if anybody can give me any pointers on this problem. It started off in the summer when I had the programmer on HW only. I put my hand on one of the downstairs rads and it was hot! The room stat is turned totally down as well.
The motorized valve seems to work O.K, I can see that the lever on it moves to HW when only HW selected, CH when only CH selected and mid-position when both HW and CH required.
thanks in advance for any ideas.
BTW It is a Potterton Statesman boiler fully pumped/sealed system with Siemens Programmer, Room Thermostat, 3 way MV
