CH Integral Gain allows the cascade response to be ad-
justed for a central heating call. CH Integral Gain has the
greatest inuence when the system temperature is close to
the setpoint.
Adjust the CH Integral Gain value using the LEFT or RIGHT
keys, then store the setting with the OK key.
• Increase CH Integral Gain
- The Cascade System will take longer to reach the set-
point, but setpoint overshooting is minimized.
- If the setpoint is reached too quickly, increase the CH In-
tegral 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 Integral Gain
- The Cascade System will reach setpoint faster, but over-
shooting the setpoint may occur.
- To reach the setpoint faster, decrease the CH Integral
Gain value by 2. Perform Cascade Autodetection and
initiate a central heating call. Observe the cascade re-
sponse and make further adjustments if necessary
Default: 245
Please consult Triangle Tube’s technical Support
before making any adjustments. Improper adjust-
ment of CH Integral Gain could lead to temperature
fluctuations and erratic cascade operation.
