Staging Control
Differential Between All Stages
The thermostat provides Differential settings between all
stages. The equipment changes stages based on how far
the indoor temperature is from the setpoint. Differential
settings provide a way to balance comfort and
conservation.
Heat Differential
The indoor temperature must drop to the selected
differential setting before the thermostat will turn on the
stage of heating. For example, if stage 2 is set to 2 °F (1.0
°C), the indoor temperature must be 2 °F (1.0 °C) away
from the setpoint before stage 2 turns on. When set to
Comfort, the thermostat will use the stage of heating as
needed to keep the indoor temperature within 1 °F (0.5 °C)
degree of the setpoint. The thermostat turns on stage 2
when the capacity on stage 1 reaches 90%.
Cool Differential
The indoor temperature must rise to the selected
differential setting before the thermostat turns on the
stage of cooling. For example, if stage 2 is set to 2 °F (1.0
°C), the indoor temperature must be 2 °F (1.0 °C) away
from the setpoint before stage 2 turns on. When set to
Comfort, the thermostat uses the stage of cooling as
needed to keep the indoor temperature within 1 °F (0.5 °C)
degree of the setpoint. The thermostat turns on stage 2
when the capacity on stage 1 reaches 90%.
TO CHANGE DIFFERENTIAL SETTINGS
1. Select Advanced Options to view/adjust differentials
between all stages.
Fig. 163.
2. Default is Comfort. Adjust differentials as needed.

Backup Heat Droop
A Backup Heat Droop is available for any system with 2
heating types. For example:
• Heat Pumps with any type of Backup Heat
• Radiant Heat with any type of Backup Heat
• Hot Water Fan Coil with any type of Backup Heat
The Backup Heat Droop restricts backup heat during the
following conditions:
•Normal Operation
• Manual Setpoint Changes
The options are:
• Comfort – keeps temperature within 1 degree of the
setpoint.
• 2 to 15 °F – Backup heat is not used unless the indoor
temperature drops to the selected Backup Heat Droop.
For example, if the Backup Heat Droop is set to 2 °F (1.0
°C), the indoor temperature must be 2 °F (1.0 °C) away
from the setpoint before the backup heat turns on.
NORMAL OPERATION
When the Backup Heat Droop is set to Comfort, the
thermostat uses backup heat as needed to keep the indoor
temperature within 1 °F (0.5 °C) of the setpoint. The
Comfort setting is NOT an option on heat pumps with fossil
fuel backup heat.
When the Backup Heat Droop is set to 2 °F or higher,
backup heat is not used unless the indoor temperature
drops to the Backup Heat Droop setting or the Backup Heat
