Finally, you will find in this page the steps followed to integrate and import the boiler information in weeWx. In this second entry, the Arduino controller developed to manage via WiFi the boiler is presented. In the current post I will summarize the existing information regarding the EMS Bus protocol. I have divided this tutorial in three parts. Luckily, Buderus boilers use a partially-documented protocol to communicate the controllers with the heating modules. However, after the first winter living in the house went by, I noticed that controlling the house’s temperature was not easy.įor this reason I started to search for ways to control the boiler remotely. This method, called by Buderus weather-compensated control, was supposed to calculate the flow temperature in accordance with a heating curve configured. For this reason, the reference temperature used by the system to heat the house is an outside sensor. Due to their situation, the room temperature measurement cannot be used to adjust the heating level. The installation is managed with a RC 35 Room Controller and a MC10 + BC10 Basic Controllers placed inside the boiler room. In the house where I am currently living there is an old Buderus boiler. 4.11 0x3F – Switching Program Heating Circuit 1.4.9 0x3D – Working Mode Heating Circuit 1.
