Thermostat for recycle pump at heating system

   For heating system using wood or another solid combustible materials who use recycle pump, I design a simple thermostat to power the pump just if water temperature is bigger than desired temperature.
   Schematic is simple
   Tom, a friend of mine, made practical system with Arduino Nano on PCB:
Using DS18B20_thermostat.ino sketch system work like in this photo:
- when temperature of heating water is bellow than desired temperature pump is off
- when temperature of heating water is bigger then desired temperature pump is powered.
Tom made more tests with sistem:
    Tom made 2 movie (speak in romanian language):

  1. salut imi da aceasta eroare la compliare . am mai facut proiecte cu interfata i2c si mi au functionat. no matching function for call to 'LiquidCrystal_I2C::begin()'
