So I found the grant controller, helpfully situated under some pipes! Unfortunately it shows nothing on the screen and the on/off button does nothing so it looks like no power to it or its bust. I asked the ladies brother to try to contact the installers again. Any helpful ideas?

Some photo's would be helpful.

If your installer thinks it is acceptable for the controller to be located under some pipework and possibly not be connected, it would make me question his competence.

I didn't think the HP would work at all without the controller working. Maybe it has some default cycles that enable it to work to some extent? The manual states that turning off the controller turns off the HP though.

I assume when you open the door at the front of the controller, nothing lights up and there is no green light at the top left of the controller (which you can see in @Allyfish post of 27/10/2023).  

To turn the controller on/off you need to press and hold the on/off button (located at top left of front of controller, with the lights on it) for 3 seconds. Assume you've tried this?  If it's dead then no idea where you go without getting hold of the installer.

@derek-m I agree!, not my installer though Derek, just helping out someone. I knew Grant discouraged people messing with their controller, but this takes it to a whole new level 🙂 Fortunately I was able to wiggle it off its mounting plate in order to be able to open the flap!

I think it must have worked when it was put in, but nothing now. I didnt have a multimeter with me so the ladies brother is going to check it out.

That's quite an installation choice for the primary user controller.  They didn't bother with any pipe insulation either I see.

@mikefl Not in the airing cupboard, I can only pray about the loft! But at least she is warm and has hot water now 🙂

@bontwoody well done in helping a vulnerable person out. What a monumentally stupid controller installation location. Do you know who the installer was? We really need to call out such appalling workmanship, not to mention the pipes left uninsulated.
