Housing for installation on DIN rail - D2MG. Occupies only 2 DIN modules.
The 220V > 5V power supply is already on the board, so additional power supplies are not needed.
-To save money, 2 levels are ordered as one board. After manufacturing, the boards need to be divided into 2 parts - upper and lower. The boards are inexpensively ($2/5pcs) manufactured at JLCPCB.
+To save money, 2 levels are ordered as one board. After manufacturing, the boards need to be divided into 2 parts - upper and lower. The boards are inexpensively ($2/5pcs) manufactured at JLCPCB (Remove Order Number = Specify a location).
Some components can be replaced with similar ones (for example use a fuse and led with legs). Some SMD components (for example optocouplers) can be replaced with similar SOT components. Most of the components can be purchased inexpensively on Aliexpress, the rest in your local stores.
The outdoor temperature sensor must be connected to the **TEMP1** connector, the indoor temperature sensor must be connected to the **TEMP2** connector. The power supply for the sensors must be connected to the **3.3V** connector, GND to **GND**.
**The opentherm connection polarity does not matter.**
