Humidity - Lennox iComfort E30 User Manual

NOTE: When set to Perfert Temp, the heat / cool position indicator changes. The
blue color (cooling) indicator is on the left and heating (red) indictor is on
the right. This is just the opposite on how it is displayed in normal heat/cool
mode. Also the heat / cool mode indicator will display Auto instead.
2. Select Heat Pump Mode: (only available with system using a heat pump).
Options are normal and comfort. Default is normal. Descriptions for what each
setting does is displayed on the screen.
3. Wider Set-Point Range: Changes the default low and high maximum
temperature setting from 60-90°F to 40-99°F (15.5-32.0°C).
4. Auxiliary Heat*: (only on heat pump systems): An additional heat source will
be used automatically when the indoor temperature drops to a temperature
that can be adjusted using the slider temperature setting tool.
5. Safety Protection: Alerts you if the home gets too cold or hot. This is set
under this menu option on the setting for both low and high temperatures. The
system will automatically turn on either cooling or heating if the home's interior
temperature reaches either the low or high setting. A notification is also sent to
the Home screen notification area and iComfort Thermostat App.
MORE ON AUXILIARY HEAT
Auxiliary heat is the use of an additional heat source, when the heat pump BTU
capacity is not sufficient to keep up with the home's heating demand; sometimes it
is also called supplemental heat.
When used in a dual-fuel mode, auxiliary heating is accomplished with a gas or oil
fired unit. In this mode of operation, the heat pump must shut down and uses just
the auxiliary heating unit for heating.
If the system is an air handler with electric heat, the auxiliary heat will be in
conjunction with the heat pump when the home heating requires it.
Another use of auxiliary heat with heat pump systems includes a setting called
balance point. Balance point puts temperature limits on when the heat pump
and electric heat work together or independently. When the outdoor temperature
is above the default high balance point of 50°F (10°C) (default), only the heat
pump will be allowed to run (no auxiliary heat). When the outdoor temperature is
below the default low balance point of 25°F (-4.0°C) (default), only the auxiliary
heat is allowed to run (no mechanical heat pump operation). When the outdoor
temperature is between the low and high balance point settings both heat sources
are allowed to satisfy the heating demand.

HUMIDITY

there is a call for heat and humidification.
• Max — Recommended for drier climates. This runs the humidifier when there is
a call for humidification only.
Dehumidification Control Center
When dehumidify is enabled, the options are as follows and are dependent on
equipment type and accessory installed.
• Normal — Recommended for moderate climates. This runs the dehumidifier
when there is a call for cooling and dehumidification.
• Max
» Single and Two-Stage Outdoor Units or Modulating outdoor units without
a Discharge Air Temperature Sensor (DATS) Installed. Recommended
when outdoor air is excessively humid. May cool your home below the set
temperature.
» Modulating Outdoor Units with DATS installed. Recommended when outdoor
air is excessively humid. Adjusts cooling based on duct sensor data. May
cool your home below the set temperature.
Dehumidification Set Point
The slide bar adjustment tool allows selection between 40% to 60%.
Humidification Accessory Installed

when a humidifier is installed. When installed, a dew point slider bar option will
appear under the humidity menu. By default the dew point slider is set to OFF.
Humidify
• When Humidify is selected, options under Humidification Control Center are
normal, max and dew point option to ON or OFF. Default is OFF.
• Humidification set points are adjustable. Range is 15% to 45% humidity. Default
is 40%.
• When dew point is set to ON, the slide bar adjustment appears with a range of
-15% to 15%. Default is 0%.
Dehumidify
• When Dehumidify is selected, options under Dehumidification Control Center are
normal, max and Climate IQ (Auto), depending on hardware configuration.
