DHW Proportional Gain allows the cascade response to
be adjusted for a domestic hot water call. DHW Proportion-
al Gain has the greatest inuence when the system tem-
perature is far away from the setpoint.
Adjust the DHW Prop. Gain value using the LEFT or RIGHT
keys, then store the setting with the OK key.
• Increase DHW Proportional Gain
- The Cascade System will reach setpoint faster, but over-
shooting the setpoint may occur.
- To reach the setpoint faster, increase the DHW Proportion-
al Gain value by 2. Perform Cascade Autodetection and
initiate a domestic hot water call. Observe the cascade re-
sponse 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 Autodetec-
tion and initiate a domestic hot water call. Observe the cas-
cade response and make further adjustments if necessary.
Default: 7
Please consult Triangle Tube’s technical Support be-
fore making any adjustments. Improper adjustment
of DHW Proportional Gain could lead to tempera-
ture fluctuations and erratic cascade operation.
NOTICE
DHW Integral Gain allows the cascade response to be
adjusted for a domestic hot water call. DHW Integral Gain
has the greatest inuence when the system temperature is
close to the setpoint.
Adjust the DHW Integral Gain value using the LEFT or
RIGHT keys, then store the setting with the OK key.
• Increase DHW 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 DHW
Integral Gain value by 2. Perform Cascade Autodetection
and initiate a omestic 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 over-
shooting the setpoint may occur.
- To reach the setpoint faster, decrease 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
Default: 245
Please consult Triangle Tube’s technical Support be-
fore making any adjustments. Improper adjustment
of DHW Integral Gain could lead to temperature fluc-
tuations and erratic cascade operation.
