Thanks BeeR . What I am looking for is, to be able to increase the SP upper limit for in the code and function menu in the STC 200 that I have the F3 upper limit max is 70* C, can it be increased aand how?
STC 1000 Is too big size wise its has to replace Grainfather STC as the set button won't engage.It looks like it can’t be raised without hacking the firmware.
What are you trying to achieve?
Can you sub out the STC200 for an STC1000?
