Stage 2 HP Lock Temp
The User shall be able to select the STG 2 HP lock temp from 40F, 45F, 50F, 55F or OFF. The value is used
in dual fuel algorithm to lock the second stage of compressor .The default is OFF which means it is disabled
and is not used in dual fuel algorithm. If system has only 1st stage equipment, this item is hidden from installer
screen. For more information see “Stage 2 HP Lock Temp” on page 28.
Feels Like
This feature will display the home temperature based on a combination of inputs. Feels Like uses outdoor
temperature, indoor temperature, and indoor humidity to determine the “feels like” condition of the home.
Wider Set Point Range
By default your thermostat operates within a range of 60-90°F. Enabling this options changes the range to
44-99°F.
Heating Mode: Normal
or Comfort
Options are Normal and Comfort. Default is Normal. When changing to Comfort Mode, several parameters
are automatically modified for optimal system operations. The changed parameters are listed on the screen
when set to Comfort.
• Normal - This setting cools the home to the desired temperature setting. Once second-stage is activated
by timer or differential, it will not stage down to first-stage until the next heating cycle demand.
• Comfort - This is when the system could automatically stage up or down based on the current load
demand.
Smart Away
This setting when enabled controls the temperature in the home when no one is home. For this to function, the
Lennox Mobile app needs to be installed on a mobile device.
Low Balance Point
(Multistage Heat Pump Model only) -The default is 25°F. This option will only be available if an outdoor sensor
is installed. If the outside temperature is below the programmed Low Balance Point, then the compressor stage
operation is disallowed. This protects the compressor from operation and damage in cold outdoor tempera-
tures. Also, if the heat pump is not effective at a low outdoor temperature, then it is more comfortable and effi
-
cient to go directly to the second stage. Low Balance Point can be disable in this screen. When this is enable,
the options are from –40°F to (the High Balance Point temperature -2) in 1.0°F steps.
High Balance Point
The default is 50°F. This option is only available if an outdoor sensor is installed. If the outside temperature is
above the High Balance point, then the auxiliary heat stage is disallowed. This prevents the more expensive
auxiliary heat stage from operating, and forces the more efficient heat pump to satisfy the demand. High
Balance Point can be disable in this screen. When this is enable, the high balance point range is from (the low
balance point + 2) up to 75°F.
Deadband
The deadband setting is the minimum difference between the cooling and heating setpoints. This setting is
used in auto-changeover to ensure smooth equipment operation. It also allows for flexibility of Humiditrol oper
-
ation. The default deadband is 3 and the deadband is adjustable from 3 to 9
°
F degrees.
