Turning up the immersion

[Tom]

I've finally had a working eddi diverter fitted and I'm trying to max out my usage, it seemed to cut out at just below 50 degrees, so I turned up the immersion thermostat but the tank still only reaches 55 degrees before the eddi stops. Attached is a picture of the thermostat. Presumably it must go higher, especially if it's going to do a legionella cycle, any idea how I can turn it up to eleven?

I found with a diverter I was only getting to mid to high 50s. Not sure if it just the lower power input that screws thing up. Now divert differently, so the immersion only gets full power (3kW) and now can get to 70 degs.

 

Have you tried switching the immersion on diverting past the diverter to see where it ends up?

[Tom]

Thanks @JohnMo, I was diverting a full 3kW after lunch and it still cout out. I'm not sure how to switch on the immersion manually tbh, I guess through the ecodan FTC?

You may find that diverting more slowly will let the tank absorb more heat before the thermostat cuts out by letting heat dissipate better in the tank.

 

I have a grid limit of 8A/2kW set for my Eddi (immersion and heat battery downstream).

This is not "advice" but mine (different make design) came to a dead stop against a flimsy plastic pip and maxed out at barely 60 degrees.  Turning it a "little" harder the pip broke off.  I then turned it further a little each day noting now hot the cylinder got before it cut off.  I stopped at 75 degrees.

 

If you try anything similar, entirely at your own decision and risk.

Looks to me like it could go higher (anticlockwise)

Ah, this was my "before" photo of the thing before I adjusted it, in case I needed to put it back. Now fully anticlockwise

Assuming it fully anticlockwise now, can you remove that plastic quadrant and reposition it a (good) bit to the right to see can you then turn the adjustment more anticlockwise.
