@derek-m I had tried just turning off at the display power button but that didn’t work and I was panicking as we’re about to have the external volumiser retrofitting. I was just thinking “this is going to be an absolute faff now if this controller is knackered”. 

after what you said I went to the consumer unit and flicked the switch to turn the whole thing off and then after 10 seconds and a short little boot up, it worked. Phew! 😮‍💨

@derek-m The human race is screwed if ever "turning it off then turning it back on again" stops working 😀

Good Evening, not been on for a while since the EHG sorted our system out. 
Well, control side of things. 

I'm at peace now, Well not quite as I think there’s more to wring out of the 17kw beast yet. 
Did anyone have the homely installed to run there systems more efficiently?

Old barn we are in but totally stripped out and plenty of insulation. Starting to cool off a bit now in Lincolnshire. 2.5c this morning. 
19c inside which is fine
resisting cranking those thermostats up to start the pump off. 

Anyone else caved in?

Run ours 24/7 when we do start again. Think FT is at 32c atm. Not looked since April tbh.

We went from cooling mode to heat mode the next day, let the heat run for the last week, but I am in NE Scotland and the temps started to drop quite quickly.
