7.0 Cascade
7.5.9 CH Proportional Gain Default: 7
CH Proportional Gain allows the cascade response to be adjusted for a cen-
tral heating call. CH Proportional Gain has the greatest influence when the
system temperature is far away from the setpoint. Press the LEFT or
RIGHT buttons to adjust the CH Proportional Gain then press the OK
button to store the setting.
• Increase CH Proportional Gain
- The Cascade System will reach setpoint faster, but overshooting
the setpoint may occur.
- To reach the setpoint faster, increase the CH Proportional Gain
value by 2. Perform Cascade Autodetection and initiate a central
heating call. Observe the cascade response and make further
adjustments if necessary.
• Decrease CH 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 CH
Proportional Gain value by 2. Perform Cascade Autodetection
and initiate a central heating 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 CH Proportional
Gain could lead to temperature fluctuations and erratic cascade
operation.
7.5.10 CH Integral Gain Default: 245
CH Integral Gain allows the cascade response to be adjusted for a central
heating call. CH Integral Gain has the greatest influence when the system
temperature is close to the setpoint. Press the LEFT or RIGHT buttons to
adjust the CH Integral Gain then press the OK button to store the setting.
• Increase CH 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 CH Integral
Gain value by 2. Perform Cascade Autodetection and initiate a
central heating call. Observe the cascade response and make fur-
ther adjustments if necessary.
• Decrease CH Integral Gain
- The Cascade System will reach setpoint faster, but overshooting
the setpoint may occur.
