The Throttling Range brackets the setpoint setting, e.g., if
the setpoint is 72°F and the throttling range is 10°F, then
the effective throttling temperature range is 67°F to 77°F.
In heating mode, the Differential is below the setpoint. The
relay de-energizes when the temperature rises to the
setpoint. As the temperature drops to the setpoint minus
the Differential, the relay energizes.
In cooling mode, the Differential is above the setpoint. The
relay de-energizes when the temperature falls to the
setpoint. As the temperature rises to the setpoint plus the
Differential, the relay energizes.
