Last night I came home to a cold house and found a flashing battery icon on my Danfoss FP75 programmer. After a little investigation I sourced the problem to a blown 3A fuse. I replaced the fuse and the flashing battery icon disappeared. It was getting late and I left it without checking the HW & CH worked ok.
This morning however, same problem....
For a full picture, when I got home the evening before I noticed that "someone" had left the hot water tap running in the ensuite bathroom all day . Could that have caused a pump motor to burn out causing a short circuit?
I am not very plumbing savvy but I have identified the following bits of hardware in the system:
Danfoss FP-75 HW & CH programmer
Grundfos 25-55G pump
2 * Honeywell F6 9409 small boxes that sit on the pipes coming from the hot water tank
I think thats it
Any ideas?
