Solar controller and thermostat<\/h1>\n
Website under construction … To Be Continued … The collector is controlled very simply – the temperature measured by the collector and the water heating tank (boiler). When the water temperature in\u00a0the solar collector is higher than\u00a0 boiler, controller turns on the pump and the heat transfer from the collector to hot water storage begins. When the temperature difference decreases, the circulation pump is turned off.\u00a0Controller described here, works as follows:<\/p>\n
    \n
  1. When the temperature difference between the solar collector and the tank more than 5 degrees, the switch is turned on.\u00a0Temperture is measured and displayed on the screen constantly, but the difference is checked every 15 seconds.<\/li>\n
  2. When the temperature difference between the solar collector and the tank is less than 2 degrees, the relay is switched off.\u00a0Difference checked every 15 seund\u017ei\u0173.<\/li>\n
  3. Potentiometer can ask any number from 0 to 100, it rodomasekrane.\u00a0When the 3-ber sensor temperature reaches the limit switches 2nd relay.\u00a0Temperature falls below the limit switch turns off.<\/li>\n
  4. Instead of the two sensors (solder the two resistors or cut the track plate) can connect another 2-channel relay module and the necessary sensors connected sequentially on a single cable.\u00a0For the controller to work after such changes require minimal improvements to the program.<\/li>\n
  5. DS18B20 sensors can be connected 2 or 3 wires.<\/li>\n
  6. The display shows the boiler temperature, collector temperature, temperature difference, 3-ber temperature sensor, potentiometer preset temperature, relay status.<\/li>\n<\/ol>\n

    Below is a screen model explanation:\u00a0K44, 62\u00a0– the collector temperature 44.62 degrees,B34, 52\u00a0– boiler temperature is 34.52 degrees,\u00a0S10, 20\u00a0– the collector temperature is higher than the boiler 10.20 degrees, a pointer to the top of the first row shows the pump control switch is turned on.\u00a0In the second row the number 28 is a potentiometer set temperature value.\u00a020.15 is a third temperature sensor value.\u00a0Among these figures, the arrow down to show that the second switch is turned off, because the measured temperature is lower than set.\"The<\/a> Widget used the following modules:<\/p>\n\n\n\n\n
