Mode
(Lennox Variable
Capacity Heat Pumps)
Options are Normal and Comfort. Default is Normal. The normal setting heats the home to the desired temperature setting. Modify the heating comfort mode to limit
minimum compressor speed to 60 – 70 percent range and/or adjust comfort mode CFM.
• Normal is when the heat pump will heat the home will providing the highest efciency.
• Comfort is when the heat pump will deliver warmer air for comfort, but sacrices on efciency.
Humiditrol Comfort
Adjust
Options are Maximum Overcooling, Midpoint Overcooling and Minimum Overcooling. Default is Maximum Overcooling.
• Maximum Overcooling: Indoor temperature > (greater than) two degrees above heating setpoint.
• Midpoint Overcooling: Indoor temperature > (greater than) HEAT setpoint + COOL setpoint / 2.
• Minimum Overcooling: Indoor temperature > (greater than) two degrees below cooling setpoint.
NOTE: Lennox variable capacity outdoor units are not compatible with Humiditrol (EDA).
Humidity Reading
Calibration
If it is determine that the actual humidity percentage being detected at the thermostat is off based on independent readings using other humidity reading devices, the
display can be adjusted using this setting.

Lock In 2nd
Stage HP by
Outdoor Temp
(Lennox Two-Stage
Communicating
Heat Pumps Only)

This setting will limit the highest humidication setting on the thermostat. This parameter will only appear when a humidier accessory is installed. Range is 15 to 45%.
Default is 45%. Adjustments are in increments of 1%.
Min Cool
Setpoint
This setting will limit the lowest cooling temperature setting on the thermostat. Range is Range is 60.0 to 90.0°F (15.56 to 32.22°C). Default is 60°F (15.56°C).
Adjustments are in increments of 1°F (0.56°C).

Modulating
Cooling Cycles
Per Hour
(Lennox Variable
Capacity Outdoor
Units)

“OFF” at the selected cycles per hour to maintain the settings of the thermostat. (This governs how many cycles per hour the system will try to run when it needs to run at
less than minimum capacity).
Range is 3 to 6 cycles hours. Can be adjusted in increments of 0.5. Default is 4.
