Thermostat works just like the one controlling the heat and AC in your house. You set it to the desired temp, the heat source activates (turns on the heat) until the desired temp is reached and then turns off. That is the “on/off” type thermostat such as jumpstart brand. Proportional thermostats such as herpstat will gradually increase the amount of power supplied to the heat source and then reduce or cut off power to the heating element once the set temperature is reached. Just like when you have the heat on in your house in the winter. Without a thermostat the heat would just crank until it’s 200* in your house. The thermostat is a regulatory device to prevent that from happening. No different in the case of heating a reptile enclosure
