Vidmas30 Posted October 6, 2010 Report Share Posted October 6, 2010 Good evening, I want to ask for advice: now programming heating system, where in MANUAL mode user enter temperature SP (flow temperature) and in AUTO mode user picks (sets) heating curve (attached), and SP changes automatically according outdoor temperature. My question is: I need to "programm" these curves in v570. I have an idea to use datatables where I set assosiations for flow temperature (SP) with outdoor temperature for each curve for example with resolution of 0.5 C (outdoor temperature). Maybe someone has done something similar before, and have some sugestion how else it could be done? Thank you very much! V.S. Quote Link to comment Share on other sites More sharing options...
MVP 2023 Joe Tauser Posted October 7, 2010 MVP 2023 Report Share Posted October 7, 2010 What is the error if you approximate each curve with a linear equation? Joe T. Quote Link to comment Share on other sites More sharing options...
Vidmas30 Posted October 7, 2010 Author Report Share Posted October 7, 2010 Hi, Joe, You are right, linear equation I think is will be the best way:) Now I need to figure it out how to make SP change only if outdoor temperature changes by 1 degree, because measurement is by 0.1C Quote Link to comment Share on other sites More sharing options...
