Hi Folks. This a question for all the solar wizzes out there
Since the end of the warm weather last week my pump on the solar installation is refusing to turn off, even at night.
I'm just wondering is this down to a faulty sensor or faulty controller. I have taken out the lower sensor to see if is working( partially immersing in warm water) and this cuts out the pump. When I insert the sensor back into the probe in the cylinder the pump turns on and will not turn off.
I have checked for reversed circulation and this is not happening.
I have also checked the settings on the controller and they match the factory settings.
I am now having to manually turn off the controller by night, but this will be overridden after eight hours and the pump turns back on.
There is very little heat generation at the moment due to cloudy weather but I don't like the idea of a pump running continuously preferring it to cycle on and off which was the norm up until the weekend
The system has worked very well since it was installed three years ago(new house, two flat plates, potterton controller).
I have contacted the plumbing contractor who done the install but he is not getting back to me with any solutions.
Any Ideas?
