Description
HP Heating
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 efficiency.
•
Comfort is when the heat pump will deliver warmer air for comfort, but sacrifices on efficiency.
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 se 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.
Range is -10.0 to 10.0%. Default is 0.0%.
Lock In 2nd
Stage HP by
Outdoor Temp
(Lennox Two-Stage
Communicating
Heat Pumps Only)
This accessory allows the unit to lock in second stage HP heating when the outdoor temperature goes below the jumper pin setting.
Options are off, 40°F (4°C), 45°F (7°C), 50°F (10°C) and 55°F (13°C). Default is off.
Max Heat
Setpoint
The highest temperature setting that the heat set point can be set on the thermostat. Default is 90.0F (32.33°C). Range is 60.0 to 90.0°F (15.56 to 32.22°C). Adjustable in
increments of 1°F (0.56°C).
Max Humidification
Setpoint
This setting will limit the highest humidification setting on the thermostat. This parameter will only appear when a humidifier 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).
Min
Dehumidification
Setpoint
This setting will limit the lowest dehumidification setting on the thermostat. Range is 40 to 60%. Default is 40%. Adjustments are in increments of 1%.
Minimum Gas
Heating Off Time
Range is 2.5 to 10 minutes. Default is 1.5 minutes. Adjustable in increments of .5 minutes.
Modulating
Cooling Cycles
Per Hour
(Lennox Variable
Capacity Outdoor
Units)
This feature is activated when the structure BTU load is less than the minimum outdoor unit cooling capacity of the outdoor unit. The system will be cycled “ON” and
“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.
