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

* {{pl|2807|DINCASE-MB3PICO}} : controler based on Raspberry-Pi Pico

−

* {{pl|2737|DINCASE-2R-BP3MOD}} : 2 relays backplane

+

* {{pl|2737|DINCASE-2R-BP3MOD}} : 2 relays backplane

+

* {{pl|151|TMP-DS18B20-WP}} : a DS18B20 OneWire temperature sensor.

+

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

+

# * DS18B20 is connected to 1Wire port

+

# * Rel 1 control the Heater

+

# * LED 1 reflect the Rel 1 state.

+

#

+

# * Button 1 invert (force) the state of the relay.

+

# * Forced state is canceled with the thermostat state reach the forced state

+

# * Forced state is canceled when the button 2 is pressed.

+

# * LED2 is lit while a forced state do applies

+

# * button 3 will decrease the setpoint T°. Led 3 will blick once to acknowledge.

+

# * button 4 will increase the setpoint T°. Led 4 will blink once to acknowledge.
