Adjusting Outdoor Reset Curve
The appliance CH set point along with Parameters

example of modifying the outdoor reset curve.
CH (Maximum Operating Temperature)
If an outdoor temperature sensor is not connected to
the appliance, the appliance setpoint for a heating
call will be set to the CH Setpoint. If an outdoor
temperature sensor is connected, the CH Maximum
Appliance Operating Setpoint becomes the appli-
ance setpoint on the CH Reset Curve Coldest Day.

This parameter is not applicable if an outdoor sen-
sor is not connected to the appliance. When an out-

Minimum Appliance Operating Setpoint becomes
the appliance setpoint on the CH Reset Curve
Warmest Day.
CH Reset Curve Coldest Day

(Parameter 7)
This parameter is not applicable if an outdoor sen-
sor is not connected to the appliance. When an out-
door temperature sensor is connected, the CH Reset
Curve Warmest Day is the warmest design temper-
ature of the heating system.
