hi come from the old school, traditional circuits and recently I approached the programmable, very beautiful but also complex, with the network is everything, in fact, before posting on this forum I read many web pages, but I can not understand and overcome my obstacle, perhaps for many of you trivial ... I hope to succeed otherwise I invented an alternative ..
my project is the piloting of a biomass boiler for which I have already realized a part of test circuit that reads the temperature from a probe and reports the info on a display ... turns on and off the ralay to due temperature thresholds , but then I got to the sore, I bought the dimmer in the subject of the robotdyn, which I interfaced to the small fan at 220v 80W that determines the combustion.I must say that with the supplied script works and varying the parameters you can run even at low revs with good strength ... what I can not do is set an if..else that allows me to vary the speed depending on some temperatures .. example: between 20-30% fullspeed from 31 to 40 80 % and so on ... until reaching the threshold of 90 ° that should go in modulation and then move to the minimum rotation .. and in case of overcoming I would do with a relay stop the fan .. also according to where I place the code inside the rest of the project i al tera execution of the controls in use, exemplar stops reading the temperature ..
I hope I was clear, in short I should create a thermoregulation with a dimmer .. seemed easy !!! ???
Thanks in advance
