How a thermostat's anticipator or cycle works
The control stops the heat early so leftover warmth does not sail past the set point.

From the opening
A thermostat does not only notice that the room has hit a set temperature and then snap off. In many heating systems it ends the call for heat a little early, or it cycles on purpose, so leftover heat in the equipment does not push the room well past the setting. The opening covers stopping early to avoid overshoot, the tiny heater on the old dial, and cycle rate versus short starts.
The rest of the brief — the later sections and the reading notes — opens after Stripe confirms payment.
