here's what i got so far. i know its a mess but i started working with this only yesterday, with zero experience... boiler/burner control is kinda working, but if there is something wrong with it, please let me know? still have few problems: - i need overheat prevention function for AI4, if the temp reaches over setpoint (45c) it shuts off the Q3 and the closes the valve AQ1? I tried to use analog treshold trigger to make it work with no luck. The AND block works ok for the pump and the B020 A/M input, it shuts the pump and drives the AQ1 to 0. -how can i build the analog comparator which compares AI4 (water IN temp) and AI5 (water OUT temp) when the AI5 value is larger than AI4, i want the Q3(heating pump) off for 2hrs and then back on. and it should be running for 15min without the comparator for temperatures in the piping to settle down.. I hope you understand what im trying to explain here, my english isnt that good Attachmentheatingsystem.zip (348 Downloads) |

Im sorry for the bit by bit posting, i didn't wanna open new thread for every question. The temperature curve can be linear, those are just example temperatures. I just need to edit the values. The system has three parts now. First part (upper part in the diagram) controls the burner and the tank etc for hot water. Second part (lower part in the diagram) control the floor heating system water. Third part controls the lights (not important atm, just testing) Attachmentheatingsystem.zip (341 Downloads) |
