CONFIGURATION
8.D.7.b Flue Limitation Parameters
To navigate to the Flue Limitation Parameters Screen, touch the Temp Limits Icon on the Conguration Screen, then touch
the Flue Limitation button on the Temperature Limits Parameters Screen.
The Flue Limitation Parameters Screen allows adjustment of the following parameters:
•
Manual Reset Flue – The temperature at which the unit will shut down due to exceeding a ue temperature manual reset
condition.
•
Flue Temp MIN & Flue Temp Max- The control will attempt to prevent the unit
from reaching the Manual Reset Flue lockout condition by modulating the fan
speed (and therefore, the input). Flue Temp Min is the temperature setting at
which the unit will begin to de-rate the input. It de-rates linearly until it hits the
Flue Temp Max setting, where the fan is at minimum speed.
8.D.7.c Outlet Limitation Parameters
To navigate to the Outlet Limitation Parameters Screen, touch the Temp Limits Icon on the Conguration Screen, then touch
the Outlet Limitation button on the Temperature Limits Parameters Screen.
The Outlet Limitation Parameters Screen allows adjustment of the following parameters:
• Outlet Temp Min – The outlet temperature at which the boiler will begin to de-rate, in an attempt to prevent a
manual reset high temperature outlet shut down condition.
•
Outlet Temp Max – The outlet temperature at which the boiler will shut down on
a manual reset high temperature outlet condition.
