Damper; Cooling - Lennox ComfortSense 8500 Installation And Setup Manual

• Heating Deadband - Defines the temperature
above demand start temperature that ends the
demand.
• Heating Integration Constant - The integration
time, in seconds, that is used in the damper
position control algorithm during a zone heating
demand.
• Heating Proportional Constant - The proportion
band, in degrees Fahrenheit, that is used in the
damper control algorithm during a zone heating
demand.
• Heating Supply Air Temperature Differential - The
amount warmer that the supply air temperature
must be than the zone temperature, to be used
for a heating demand.

Damper

• Minimum zone damper position.
• Maximum zone damper position.
• Zone damper ventilation position.
• Zone control loop reset position (damper starting
position).
• Zone CO setpoint for ventilation (IAQ / indoor air

quality ventilation setpoint 500-2000ppm of CO

Cooling

• Cooling Votes (1st Stage; 2nd Stage)
˃ 0:0 - No votes (no affect on system cooling
demands).
˃ 0:1 - Vote only when sensing high zone
cooling demand.
˃ 1:1 - Vote single weight vote during either
low or high zone cooling demand.
˃ 1:2 - Vote single weight during low zone
cooling demand, vote double weight during
high demand.
• Cooling Differential 1 - Defines the temperature
above setpoint that creates a low cooling
demand.
• Cooling Differential 2 - Defines the temperature
above setpoint that creates a high cooling
demand. Must be greater than Differential 1.
• Cooling Deadband - Defines the temperature
below demand start temperature that ends the
demand.
• Cooling Integration Constant - The integration
time, in seconds, that is used in the damper
position control algorithm during a zone cooling
