- connect 12V power supply,
- disconnect +5V wire from USB-UART converter.<br>
Video {- demostration "How self-tests works":-}
To check EEV connection, you can use a stepper motor as shown in the video. If you are testing a real EEV, it will be closed after the first "beep" and partially opened after the second "beep".<br>
To check temperature sensors connectors crimp one array of sensors. Plug it to all sensors connectors one-by-one and check results in a serial console.<br>
{-Photo: PCB with connected arrays of sensors (I have enough sensors, so all 3 arrays are connected except Ts2 and Treg) -}<br>
To check EEV connection, you can use a stepper motor. If you are testing a real EEV, it will be closed after the first "beep" and partially opened after the second "beep". If it's not, check if stepper or EEV center pin(s) connected to +12V and try to swap coil-end pins (EEV1..EEV4). {-EEV photo here-}

After tests completed, comment 3 self-test defines.<br>
Choose your installation scheme and uncomment one of those options:
```c
#define SETPOINT_THI //"warm floor" scheme: "hot in" (Thi) temperature used as setpoint
//#define SETPOINT_TS1 //"swimming pool" or "water tank heater" scheme: "sensor 1" (Ts1) is used as setpoint and located somewhere in a water tank
```
Re-upload firmware. Your controller is ready to a first start (after wiring). Probably you'll never need to change other options.<br><br>

## Wiring (permanent controller installation).
Here are no instructions for choosing the right placement for permanent installation of the controller. It depends. You're building your system, and you know much better "where" and "how".<br>
