Hi guys, before I start explaining my problem I would like to say hello to everyone as I’m new to this forum.
Problem:
For some reason the 3A feed fuse to my gas central heating kept blowing. I worked out that it only happened when I switched with the switches on the programmer. (ie hot water on constant or heating on, although this didn’t always happen)
For some reason the switches on the programmer now have no effect on whether the heating/water is on. In fact the only way to turn the heating/water on and off is to switch the switch on the feed spur.
I checked the 3 port valve (Danfoss HSA3) which was stuck in the central position. If I use the arm on the side to change from auto > man the 3A feed fuse blows.
I have come to the conclusion (GUESS) that the 3 port valve is the cause of this problem. Please can anyone more qualified shed some light on my situation.
I have found this problem difficult to explain so apologise if this post is in anyway confusing.
Thanks in advance.
