Hi

i hope someone can help.

I’ve had my system for over 20 years, working fine. Until earlier in the summer I noticed and error on the display ( interruption 1) my investigations found that the system wasn’t getting a signal from the sensor on the panels. So the pump hadn’t been running pushing water around the system, so as a temporary measure I bypassed the wiring and plugged the pump straight into a socket. That’s got it working again. I then have attempted to fit a thermal sensor on one of the pipes where they go out through the roof, as I am unable to get onto the roof to replace the original unit. This hasn’t worked, even though in theory that’s all the sensor does it’s just it’s position in the system, I’ve ns tried three different sensors. I did try buying a copper strap sensor one that wraps around the pipe, but for some reason that got lost in the post can’t seem to find any more of them anywhere.

thanks for reading

Neal.
