Cooling and Heating Applications
2 The TC07 can be used to control a DC fan as shown in
Figure 3. The fan turns on when the sensed temperature
rises above TSET and remains on until the temperature falls
below HSET. The amount of "over-cooling" performed by the
fan is dependent on the programmed hysteresis.
Figure 4 shows the TC07 acting as a heater thermostat.
Circuit operation is identical to that of the cooling fan
application.
