اولا:- الف شكر على المشاركه الجميله المفيده ؟؟
ثانيا:- عندي كم سوال :-
1- مافائدة المفاتحABC؟؟؟
مفتاح التشغيل
2- كم فولتية التشغل ؟؟
من12 فولت حتى 35 فولت
3- ماهي مواصفات الريلي ؟؟
relay 1 RT 12v

4- قيمة المقاومه 11 اعتقد420 لانها غير موجوده بالقائمه؟؟
420 صحيح سجبت برقم r10
ثالثا :- الاهم هل جربت الثرموستات والاهم منه في المفاقس ؟؟
قام بتجربته صديق لي كمشروع تربص
القادم احسن

This thermostat can be modified depending on the components that are available. This can be done easily with components bottom drawer ...
1 - In terms of food it can range from 12 volts to the maximum Regulator (35 Volt), if you already have a 9 volt power supply you pass the regulator and the capacitor C1. In this case the arrival of current is at point D.
2 - Regarding the relay, if you disposed of a 6 volt relay you subsequently assembled point B to C (jumper PCB). A 12 volt relay you subsequently assembled point A to C. Resistor R9 will compute a function.
The circuit can work well with 12 volts when the power is stabilized, in this case without controller C1 and the condo.
3 - This is not a requirement for a 47 K NTC, if you disposed of a 10 K NTC for example you change the value of R1 to be the same value as the NTC.
4 - For P1 if you disposed of a potentiometer 47 K for example you put the two resistors R2-R3 heels are multiplied by the same factor, 1.2 * 4.7 = 5.6 K. These two resistors make the adjustment easier, thou adapted according to your needs.
5 - For R5 (1 M ohms) if you are not disposed to such a value you can get up to 470 K
