This metallic frame is connected to protective earth but the stove has itвЂ™s own GND reference for all communicationВ stuff. First вЂ“ GND is not connected to stoveвЂ™s metallic frame. They were mentioning there is ~20V, GND, +5V pins. I knew there is a DB9 connector at the back of the stove and while I didnвЂ™t know the pinout I suspected that it may be connected to the SERIALE connector (CN13) on the main board. But that is quite crazy and unnecessarily complicated. Well, first I was thinking of parsing LCD segment bits and getting textual LCD data as a form of feedback. It sends the вЂpower setting downвЂ™В command every four seconds.В Just connect an IR LEDВ to GND and D3 pins (ideally with a 100 Ohm resistor in series).

I created a testingВ Arduino code based on Infrared library. = Setting the water and air temperature = Here is a table of commands I created by recording the IR LEDВ voltage with a PC line-in sound card port, then analysing the recording with Audacity (before I had a logic analyser at hand): = Setting the power = ItвЂ™s not difficult to send IR commands for this stove using an Arduino. As IВ also recentlyВ purchasedВ a Rigol oscilloscope and had a Salea logic analyzer available soВ I did more work on this subject and I am finallyВ able to describe it in more details. It was not all in one placeВ there and not complete.

I bought this stuff and itвЂ™s now mine so I want and will do what can be done with it myself! So I decided to spend some time with this.ДЇist I did some research on IR remote.В LaterВ I found some helpful information about the serial communicationВ inВ Italian at (thanks!). And he replied thatВ if I amВ not from one of their partner companies theyВ canвЂ™t tell me anything.

I contacted one of Micronova employees just asking if it is possible to turn on the stove via that connector or if it would be just waste of my time trying to figure out how to do it.

I noticed a DB9 connector at the back of myВ stove but no! It is not an RS232, there is 20V on one of the pins and I destroyed my UARTВ interface trying to connect it to the stove (right, I should have checked the voltage levels on each pins first, lesson learned, but the interfaceВ is not expensive and I have more pieces at home anyway). It is used by various stove manufacturers like Laminox, Extraflame, Evacalor, Dalzotto, Ungaro, Arcestufe, Karmek, Tecnoflam, Termoflam, Clam, Cadel, Zibro, Sicalor, Kepo, EcoTeckВ and many others.

By google searching pellet stove controllers I noticed that mine looks very similarly as those made by Micronova so it was clear вЂ“ the controller inside my stove is some board from Micronova (i023, i050 or who knows). So I needed a way to control it remotely. Problem is that sometimes I am outside and I want to turn on the stove remotely so that when I arrive, it will be warm inside. It is a nice thing to have over the winter. They installedВ a Laminox pellet stove in our house. Here is how to control a pellet stove with a Micronova controller remotely either viaВ IR commands or using theВ serial line.
