HIGH VOLTAGE: HAZARD OF ELECTRICAL SHOCK. DISCONNECT INCOMING POWER BEFORE WORKING ON THIS.   WARNING: This equipment should be installed, adjusted, and serviced by qualified electrical maintenance personnel familiar the hazards involved. Failure to observe this precaution could result in bodily injury.

ESP32-S3 based Home heating system controller.

Designed to use with ESPHome for:

1. Maximum flexibility
2. Ease of programming
3. Seamless integration to Home assistant.

External interfaces:

1. 6x PT100 3 wire RTD temperature sensor inputs.
2. Integrated AC solid state relay outputs:
   1. 4x smal current output pairs for actuators (mixing valves).
   2. 5x outputs for inductive loads up to 2A.
3. Uart connection for Nextion or other HMI display.
4. Button with RGB led connection.
5. Analog pressure sensor connection (With signal output up to 5V).
6. 1wire bus for additional sensors.
7. 2x dry contact inputs. For floor demand or other functions (internaly pulled to 12V).

Wire connectors:

1. For low voltage connection and  sensors:
   • Dieran DA803 or other 3.5mm pitch.
2. For High voltage AC connection:
   • Dieran DA806 or other 5mm pitch.
