Adjusting Humidification And Dehumidification Settings With; Non-Communicating Outdoor Units - Lennox iComfort Wi-Fi Installer's System Setup Manual

HEATING MODE (XP25 ONLY) — CLIMATE IQ™
This technology optimizes dehumidification settings for specific climates to
improve home comfort during cooling or heating operations.
Two climate settings are available:
• Comfort ­ The system adjust compressor operation to increase air
temperature.
• Normal ­ Standard system operation.
COOLING MODE — CLIMATE IQ™
Three climate settings are available:
• Dry ­ The system supplies higher indoor airflow at all compressor
capacities, increasing efficiency by operating at a higher sensible to
total ratio.
• Moderate ­ The system supplies indoor airflow that balances
efficiency and comfort.
• Humid ­ The system supplies lower indoor airflow at all compressor
capacities, improving humidity removal by operating at a lower
sensible to total ratio.

How Humidification Mode Works
DISPLAY, BASIC AND PRECISION—These modes allow user con­
trol of relative humidity between 15 and 45%. These conditions must
be met for either mode to operate:
• humidification mode has been enabled, and
• the unit is in HEAT mode, and
• humidification demand exists (24V present at H), and
• DISPLAY mode indicates humidification is OFF.
• BASIC mode mode also requires presence of heating demand
[Y for HP heat, or W for gas heat (W may be energized with G
de-energized)].
• PRECISION—Outdoor temperature sensor is required.
Basic Dew Point Control adjustment mode will change the humidifica­
tion setpoint based on the outdoor temperature and a user-defined
dew point adjustment setting.
Precision Dew Point Control adjustment mode will operate when these
conditions are met:
• humidification mode has been enabled, and
• the unit is in HEAT mode, and
• humidification demand exists (24V present at H).
