AVT3220 A + - thermostat with LED display. PCB and programmed layout

Description

The system is used to maintain a certain temperature in the supervised place. In the proposed solution, the temperature of switching the relay on and off is set independently, thanks to which virtually unlimited configuration possibilities have been achieved. The thermostat can work in both heating and cooling modes with any hysteresis range. Only lead-through components and a ready-made, waterproof temperature sensor were used for its construction. The whole option will fit in the Z-107 housing, which is designed for mounting on the popular "electrical" TH-35 rail. <? P>
