Hi
I have a Honeywell 927 controlling my c/h. When I set the target temp. to, say, 21c , after a while it reads .5 over. I have been into the user settings and altered the prop. bandwidth a few points at a time and have eventually reached its max. of 3.0. Still its showing .5 over at room temp. Now, my boiler stat. is set to max., so should I now keep the prop. bandwidth at 3.0 and experiment by altering the boiler stat. down a mark at a time?
Ta in advance
