Through the Auto Rotation function, the number of burn-
ing hours is equalized over all appliances.
When the function is Enabled, the appliances will all run
an equal amount of time. This helps balancing wear over
the appliances.
When the function is Disabled, there is no leveling of burn-
ing hours and the rst appliances in the sequence will run
more than the last one in the sequence.
Select Enabled or Disabled using the UP or DOWN keys,
then store the setting with the OK key.
CH Proportional Gain allows the cascade response to be
adjusted for a central heating call. CH Proportional Gain has
the greatest inuence when the system temperature is far
away from the setpoint.
Adjust the CH Prop. Gain value using the LEFT or RIGHT
keys, then store the setting with the OK key.
• Increase CH Proportional Gain
- The Cascade System will reach setpoint faster, but over-
shooting the setpoint may occur.
- To reach the setpoint faster, increase the CH Propor-
tional 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 set-
point, but setpoint overshooting is minimized.
- If the setpoint is reached too quickly, decrease the CH
Proportional Gain value by 2. Perform Cascade Autode-
tection and initiate a central heating call. Observe the
cascade response and make further adjustments if nec-
essary
Default: 7
Please consult Triangle Tube’s technical Support be-
fore making any adjustments. Improper adjustment
of CH Proportional Gain could lead to temperature
fluctuations and erratic cascade operation.
