As shown in the figure, it is a simple constant temperature controller circuit which is based on intelligent temperature sensor of IC2 bus interface. LM75 drives relay coil K by 2N3904 transistor, it can control the thermostat power supply's on/off by the high and low of the measured environmental temperature, then it can achieve constant temperature control.
