7.0 Cascade
- To reach the setpoint faster, decrease the CH Integral Gain
value by 2. Perform Cascade Autodetection and initiate a cen-
tral heating 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 CH
Integral Gain could lead to temperature fluctuations and erratic
cascade operation.
7.5.11 DHW Proportional Gain Default: 7
DHW Proportional Gain allows the cascade response to be adjusted for a
domestic hot water call. DHW Proportional Gain has the greatest influ-
ence when the system temperature is far away from the setpoint. Press
the LEFT or RIGHT buttons to adjust the DHW Proportional Gain then
press the OK button to store the setting.
• Increase DHW Proportional Gain
- The Cascade System will reach setpoint faster, but overshooting
the setpoint may occur.
- To reach the setpoint faster, increase the DHW Proportional
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 Proportional Gain
- The Cascade System will take longer to reach the setpoint, but
setpoint overshooting is minimized.
- If the setpoint is reached too quickly, decrease the DHW
Proportional Gain value by 2. Perform Cascade Autodetection
and initiate a domestic hot water call. Observe the cascade
response and make further adjustments if necessary.
Only make adjustments to this setting after consulting ACV-
Triangle Tube Technical Support. Improper adjustment of DHW
Proportional Gain could lead to temperature fluctuations and
erratic cascade operation.
