Hi everyone,
Over the last week or so, I have had an intermittent fault with the controller not switching on the hot water. Sometimes it seems to work fine and start the boiler heating other times the red light goes on the controller but the boiler doesnt fire. What I have noticed is that when it is working, the controller gives a little faint click when the red light illuminates, and when its not working it doesnt give that click.
An extra piece of information is that last year I had the heating part of the controller wired out the circuit so that my programmable room thermostat controlled the heating on and off - thats been working well.
I have the system on a maintenance contract, so I can call them out - I actually did earlier in the week but stood them down because the system started working again on the morning that they were due only to stop the following day!
My guess is that its one of the micro switches in the controller that is goosed in which case I will get the company out to replace it but my other thought was it could be loose wiring in the controller, in which case I would happily open it up and tighten the screw.
Anyone with any experience have any thoughts before I open it up or call out the engineer?
Thanks for your help.
