HELP Tpi on Honeywell room thermostats
Hi all
i have fitted two of these in the last week or so when doing a boiler change . Both customers have said that since then the heating takes longer to heat up. when I saw the rep a few months back he said that the new fangled tpi built into the stat turns the boiler off every 10 minutes for 10 minutes. This then makes the condensing boiler cool down and then work hard when re-firing, thus it will condense more.
In practice the heating just gets warmer slower. So what I have done for now is alter the pump overrun to 15 minutes from 5. This has helped a lot, but I really would like to disable the function on these 2 jobs but can't remember how to do it. ( not in instructions)
hope someone knows.
also they should mention in the instructions to extend the pump overrun, otherwise the boiler won't cool.
