Emerson Blue Wireless Comfort Interface - Homeowner User Guide
Descriptions
Selecting an outdoor temperature from 5°
to 50° turns on the Dual Fuel setpoint. As
long as the outside temperature is above the
setpoint, the compressor will operate. When
the temperature drops below the setting, the
Comfort Interface will start the gas heat and
turn off the compressor. This item appears
only if HP1 or HP2 is selected and outdoor
sensor is installed and enabled.
Select a number 1 - 9 to activate the "logic"
heat pump Dual Fuel option (no outdoor
remote sensor required). This causes the
Comfort Interface to turn off the heat pump
shortly after the furnace fires. Five (5) is the
factory recommended average setting. A
lower number slightly increases the delay
between heat pump and furnace stages. A
higher number slightly decreases the delay
between heat pump and furnace stages.
Note: This setting is not minutes or degrees.
It is a numeric setting that will influence the
internal Comfort Interface calculation for
staging.
Selects Auxiliary Heat Cut out temperature.
If the outdoor temperature is above the
selected setting, the auxiliary heat will not
turn on. This item appears only if HP1 or HP2
is selected and outdoor sensor is installed
and enabled.
