Equipment Parameters - Lennox iComfort E30 Installation And Setup Manual

Equipment Parameters

Selections listed in this section are dependent on system hardware configuration. Not all options will be available.
NOTE: When changing the default settings for any parameter, there is a possibility that it will affect the settings for another parameter. If this happens, a pop-up
message will be displayed listing the other affected parameters and their new automatically set values.
The following is a complete list of all possible parameters under System. Parameters actually available are dependent on the smart hub settings.
Parameter
Description
(In alphabetical
order)
This screen provides information concerning language supported, equipment type name, control software revision, model, control mode number, control serial number,
About control hardware revision, protocol revision number, device product level, 24VAC average power consumption, 24VAC peak power consumption, compatible devices
list, application code memory size and micro-controller part number.
Auto Changeover
Prevents the Humidification and Dehumidification settings from being closer together than 5% or greater than 10% (Dead-band).
- Humidif.
Range is 5 to 10%. Default is 5%. Adjustments are in increments of 1%.
Deadband
Prevents the Heating and Cooling from being set closer together than 3ºF (1.67°C) or greater than 9ºF (5.0°C) (Dead- band).
Auto Changeover -
Temp Deadband
Range is 3 to 9°F (1.67 to 5.0°C). Default is 3°F (1.67°C). Adjustments are in increments of 1°F (0.56°C).
Auto
Dehumidification Range is 0 - 10%. Default is 4%. Adjustments are in increments of 1%. This value can automatically be affected by adjusting other parameters. One example would be
Overcooling when enabling Max Dehumidification Overcooling.
Threshold
Balance Point Control
If system is set up as dual fuel or heat pump with electric heat and a outdoor temperature sensor connected to smart hub, the low and high balance point settings will appear. The balance points
feature requires that a sensed outdoor temperature is provided to the thermostat. The outdoor ambient temperature can be read from a field-installed outdoor temperature sensor (X2658).
When balance point control is ENABLED, the low and high balance point fields will be turned "ON" and show RED. A message will be displayed asking you to review the low and high balance
point settings and save all RED settings. Highlighted fields in RED must be saved to allow exit from that screen.
Options are enabled or disabled. Default is disabled. When enabled, both low and high balance points can be set.
High Balance Point
This setting is used to prevent the furnace or electric heat from heating the structure. (Alert 19 - Minor - Notification only - The outdoor temperature is higher than the level where the furnace or
electric heat is programmed to heat the home.)
Range is -17 to 75°F (-27.22 to 23.89°C). Default is 50°F (10.0°C). Adjustments are in increments of 1°F (0.56°C).
Low Balance Point
Setting used to prevent the heat pump from heating the structure. (Alert 18 - Minor - Notification only - The outdoor temperature is below the level where the heat pump is programmed to heat the
home).
Range is -20 to 72°F (-28.89 to 22.22°C). Default is 25°F (-3.89°C). Adjustments are in increments of 1°F (0.56°C).
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.
Cooling Mode
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 cooling cycle demand.
Comfort - This is when the system could automatically stage up or down based on the current load demand.
Default is ON. The purpose of this algorithm when set to ON is to detect systems with faults which are causing measurable loss of comfort and thus, need repair/service
Cooling Discomfort intervention.
Threshold
The algorithm monitors the duration in which the indoor temperature is above the cool set point or below the heat set point and does not approach the set-point. When
an issue is detected alarm 901 is activated.
