As the “Heat” contacts of the thermostat close, bimetal heater
#1 is energized. Approximately 45 seconds later, the warping
action of bimetal heater #1 closes line voltage switch #1 to
energize the heating load. When the "Heat" contacts open,
heater #1 cools for approximately 45 seconds before switch #1
opens to de-energize the heating load.

As the "Cool" contacts of the thermostat close, bimetal heater
#2 is energized. Approximately 45 seconds later, the warping
action of bimetal heater #2 closes line voltage switch #2 to
energize the cooling load. When the "Cool" contacts open,
heater #2 cools for approximately 45 seconds before switch #2
opens to de-energize the cooling load.
