Basic Thermostat

This project implements a basic temperature control system from a 3 modules MyDin made of:

• DINCASE-MB3PICO : controler based on Raspberry-Pi Pico
• DINCASE-2R-BP3MOD : 2 relays backplane
• TMP-DS18B20-WP : a DS18B20 OneWire temperature sensor.

The temperature sensor takes the room temperature and the heater is controled by the relay 1.

1. * DS18B20 is connected to 1Wire port
2. * Rel 1 control the Heater
3. * LED 1 reflect the Rel 1 state.
5. * Button 1 invert (force) the state of the relay.
6. * Forced state is canceled with the thermostat state reach the forced state
7. * Forced state is canceled when the button 2 is pressed.
8. * LED2 is lit while a forced state do applies
9. * button 3 will decrease the setpoint T°. Led 3 will blick once to acknowledge.
10. * button 4 will increase the setpoint T°. Led 4 will blink once to acknowledge.
