7.0 Cascade
7.5.12 DHW Integral Gain Default: 245
DHW Integral Gain allows the cascade response to be adjusted for a
domestic hot water call. DHW Integral Gain has the greatest influence
when the system temperature is close to the setpoint. Press the LEFT or
RIGHT buttons to adjust the DHW Integral Gain then press the OK but-
ton to store the setting.
• Increase DHW Integral Gain
- The Cascade System will take longer to reach the setpoint, but
setpoint overshooting is minimized.
- If the setpoint is reached too quickly, increase the DHW Integral
Gain value by 2. Perform Cascade Autodetection and initiate a
domestic hot water call. Observe the cascade response and make
further adjustments if necessary.
• Decrease DHW Integral Gain
- The Cascade System will reach setpoint faster, but overshooting
the setpoint may occur.
- To reach the setpoint faster, decrease the DHW Integral Gain
value by 2. Perform Cascade Autodetection and initiate a domes-
tic hot water call. Observe the cascade response and make fur-
ther adjustments if necessary.
Only make adjustments to this setting after consulting ACV-
Triangle Tube Technical Support. Improper adjustment of DHW
Integral Gain could lead to temperature fluctuations and erratic
cascade operation.
