Ok so this is a test piston.
As you can see it says that if the house mode is away and between those time, to heat the thermostat to 15.
That works well.
My problem is this. Let say I’m at work and I think that 15 is too low. If I go modify the piston to exemple 17 it won’t work unless I change the location to night or home and then back to away.
Anyway to fix this?
