Explanations of Set point, Swing, Differential and Dead band
HEAT mode: Thermostat controls the temperature according to the following diagram
Example: If Heat Set point = 70°F, Swing = 1°F, Differential = 2°F, then
=> 1
st
stage heater turns on when room temp is 69°F and off at 71°F.
=> 2
nd
stage heater turns on when room temp is 67°F and off at 70°F.
COOL mode: Thermostat controls the temperature according to the following diagram
Example: If Cool Set point = 80°F, Swing = 1°F, Differential = 2°F, then
=> 1
st
stage cooler turns on when room temp is 81°F and off at 79°F.
=> 2
nd
stage cooler turns on when room temp is 83°F and off at 80°F.
AUTO mode: Thermostat controls the temperature according to the following diagram.
Press + / - buttons to adjust the appropriate set point. It will adjust the set point that is
closer to the current room temperature.
 If the current temperature is close to heat set point, then it will change the heat set point value.
 If the current temperature is close to cool set point, then it will change the cool set point value.
 If the difference between the two is equal, then it will change the heat set point value by default.
 There is a dead band 4°F/2°C (by default) between heat set point and cool set point. If user select
heat set point is 73°F, then the minimum of cool set point will be limited to 77°F.
