Air conditioner thermostat T6861 is the best replacement for Honeywell T6861. It is designed for fan coil unit system controls, and is the crucial part for you to control the system. Electronic temperature controller as we know divided resistors thermostat and thermocouple temperature controller. Wherein the resistance temperature sensing thermostat a resistance measuring method, commonly used platinum wire, copper, tungsten, and a semiconductor (thermistor) used as the temperature measuring resistor, the resistor has its advantages and determined point. The thermocouple thermostat is made according to the principle of Wheatstone bridge. BD plugged at both ends E, according to Kirchhoff's law, when the bridge resistors R1 × R4 = R2 × R3, A and C points is equal to the potential, no current flows between the output terminals A and C, the size of the thermistor resistor R1 with increasing ambient temperature change or lowered, the equilibrium is destroyed, the output current between the AC. Thus, when constituting the thermostat, it can easily be changed by selecting the appropriate temperature thermistor and temperature adjustment range.
