Main Menu → Advanced Setup → Performance → Temperature Control → Setpoint Range
Setpoint Low Limit
Numeric Entry
Determines the upper and lower limit within which the
setpoint can vary.
Setpoint High Limit
Numeric Entry
Setpoint Limiting
Enable/Disable
Enables/disables Setpoint Limiting functionality.
Setpoint Limit Band
Numeric Entry
Sets the number of °F below Setpoint High Limit the
unit’s outlet temperature must fall before the unit restarts (0
to 10°F, Setpoint Limiting = Enable).
Setback Schedule
Enable/Disable
Enables/disables Setback Schedule functionality
Setback Setpoint
Numeric Entry
The Setpoint that will be in effect during the Setback
period. (60°F to 245°F, Setback Schedule = Enabled).
Setback Start Time
Numeric Entry
The Setback period’s start time (Setback Schedule =
Enable).
Setback Stop Time
Numeric Entry
The Setback period’s end time (Setback Schedule =
Enable).

FFWD Temp
Read Only
Displays the current FFWD temperature.
PID Output
Read Only
Displays the calculated PID output.
FFWD Output
Read Only
Displays the current FFWD output.
Min Load Adj
Numeric Entry
Adjusts the output by adding an offset to the breakpoint
chart at minimum flow. This is used to fine tune Feed-
Forward (FFWD) output at low flow levels. (-50 - +50°F)
Max Load Adj
Numeric Entry
Adjusts the output by changing the scaling of the
breakpoint chart at maximum flow. (-50 - +50°F)
Outlet Feedback
Yes/No
Enables Outlet Feedback functionality.
Feedback Gain
Numeric Entry
The percentage of feedback from the water outlet sensor
the algorithm factors to determine fire rate (0.01 – 1.00).
Fdback Start Pos
Numeric Entry
The Feedback start position (0 – 100%).
Fdback End Pos
Numeric Entry
The Feedback end position (0 – 100%).
Max Feedback
Numeric Entry
Specifies the maximum Feedback position (0 – 100%).
Fdback Value
Read Only
Displays the current feedback value.
Breakpt at 100 to
Breakpt at 0
Numeric Entry
Allows breakpoint temperature settings to be entered for
100% to 0% in 10% increments (60 – 260°F).
Temp Gov
Enable/Disable
Enables temperature governor limiting functionality, which
aggressively reduces the effective Fire Rate as the Outlet
Temperature approaches the High Temperature Limit.
GOV Limit-5 – GOV Limit-15
Numeric Entry
When the Outlet Temperature exceeds the Temperature
Hi Limit by 5 to 15°F, the effective Fire Rate will be
reduced by the value entered in GOV Limit-5 through GOV
Limit-15 (0 – 100°F).
Above 70F Val
Numeric Entry
If the inlet water temp is above 70F, algorithm adds offset
provided by this item to all the 11 breakpoints (“breakpoint
at 100” – “breakpoint at 0”). (-10 - +10°F)
Below 70F Val
Numeric Entry
If the inlet water temp is below 70F, algorithm adds offset
provided by this item to all the 11 breakpoints (“breakpoint
at 100” – “breakpoint at 0”). (-10 - +10°F)
No FFWD Above FR
Read Only
No Feed Forward above this fire rate
No FFWD Feature
Read Only
No Feed Forward above fire rate feature status

Purge Blower Voltage
Numeric Entry
Sets the blower speed (blower output voltage) during the
Purge cycle (2.0 to 10.0 V).
