Hi, is it normal for the fan to run continuously on this boiler? I have one fitted with UFH and rads upstairs. Even when there's no demand for heat or hot water it is running.
I seem to remember when I fitted one that happened and there was a setting that needed to be changed that they had not put in the book! Possibly that was after fitting the W/C controller though.
Problem was the owner got the fix from Vies tech before I had a chance!
I posted the answer to this question at midnight the day it was posted. My answer had been removed - with others to two different questions - by nine the next morning.
WHY?
The answer is in the book. It applies to the pump overrun on constant temperature controlled versions.
Mysteryman, sorry, didn't see your previous post. I've had a look at the book but can't find anything. Could you point me in the right direction please?
Refer to the service book. Access Code 2. Visit addresses F5, F6, and F7. Reduce the value of each to 1. These are all to do with pump overrun on constant temperature boilers.
