dndrich - That’s correct.
PS: The offset of 10 is for Celsius, rather than Fahrenheit.
So, in Celsius (my brain melts in Fahrenheit but I’ll try my best), with an offset of 10C:
103C inside boiler, display shows 93C. That’s 10C difference.
Now in Fahrenheit:
That’s 217.4F and 199.4 respectively. That’s 17F difference.
I’m wondering… Should the Coffee temperature offset when the machine is operating in Fahrenheit, That’s setting EC, therefore be 17 rather than 10?
For you to have an idea:
My machine often displays 9C first thing in the morning when the environment temperature is around 20C on the thermostat.
Of course I might be talking nonsense, but this is definitely something which has crossed my mind before.
