OBA7 Compensated heating control

countrygent Posts: 2 Rating: (0)	Hi all, I am wanting to write a program to control a domestic heating boiler. I have an analogue temp sensor indoors and one outdoors, probably both PT100. The setpoint of the system will be set manually. I should like a PI control loop to maintain the setpoint but if the outside temp starts dropping, the boiler will heat more in order to compensate so that the room does not cool too much. The output to the boiler is 0-10v and the heat output of the boiler is proportional to that signal. Does anyone know of any articles or snippets of code that would help with this? Thanks.

A lot of threads about "Temperature control" and "analog calculation by logo" for example the following links: 1) Temperature Regulation 2) Curve Temperature Logo 3) CO2 calculation - Math equations with LOGO! I guess this links are enough for your application, however if you have a specific un answerd questions let us know
