Differential
0 °F to 5 °F or 0.0 °C to 2.5
°C
Differential is the minimum number of degrees rise
or fall required during off cycle to switch from the
last active mode (heat or cool) to the opposite
mode when the thermostat is in auto-changeover.
Differential is NOT deadband. The deadband
temperature between when heating (or cooling)
cycles on and cycles off to maintain setpoint is not
adjustable. The thermostat uses an algorithm that
fixes deadband at 0 °F (0 ° C).
