I was curious so I have just been out to check the resistance of my capacitors and the compressor, so I know in future if I have the same problem is it the capacitors or is it the compressor. This is on my IVT HT+ E9, so your values may differ slightly.
With everything wired up, but the GSHP switched off
Compressor Run Winding 1.5ohms - Terminal 2/N (Common Blue Wire) to 4/T1 (Run Black Wire) on the Danfoss Soft Starter
Compressor Start Winding 2.3ohms - Terminal 2/N (Common Blue Wire) to Brown Wire connected to Run Capacitor (Smaller silver one) (or Terminal 2 on Start Relay)
Capacitors - Check for short circuit. You should get a reading across the terminals which will then rise to open circuit (OL). This is easiest to check by checking between 1/N and 3/L1 on the Soft Starter.Ah thanks for that will pass it on to my electrician. Funnily enough he was over at the weekend writing details down for the capcitors. We sat there for 2 hours waiting for it to trip - nothing!Going to replace them just in case though
Fingers crossed new capacitors get fitted this weekend, the error is happening hourly now!
Not yet, he's doing all that at the weekend (hopefully)

So literally a mixer type valve that I adjust couple of times a year till I'm happy with the temp? And this connects to my existing radiator pipe work. I will ask my plumber just want to get my head around the concept first.

Hi, turned on heating from our ecoforest GSHP today. We’ve not used heating much since it was installed in March, just occasionally in spring and it worked fine then and has happily given domestic hot water. Now, after the heating being on today for 45 mins and starting to warm up the radiators, it gave error code “pCOe number: 1. pCOe offline”
The user manual doesn’t include a list of error codes and says to contact the installer which we’ll do on Monday, but in the mean time does anyone know what the issue might be?0 -
Hi @Strummer22
My IVT unit has several RCD breakers inside, accessible by removing a couple of screws and the front panel. If I had a similar problem to you I'd be checking that none of these have tripped. No idea if your Ecoforest unit has similar RCD's or removable cover.
From a look at the manuals I couldn't discern any more than you but this or similar might be your pCOe

Hi @Patrol
I appreciate the advice. I took the front panel off but there's another panel below with about 20 screws before you reach any components. I'm not the most technically savvy and clearly the manufacturer doesn't want unqualified users messing with it. We're not freezing cold so I think I'm willing to wait for the experts.
and @beardymarrow I don't know how to do a system reset, that option doesn't seem to be available from the menus. I did turn power to the control unit and compressor off and on again though - no luck.

No, sounds sensible as anything intended for the consumer shouldn't be hidden behind that many screws so best to wait. Hopefully they will get it working and advise if there is anything you can do yourself in future.
