The Cascade Settings menu contains settings relat-
ed to cascade operation. Each line contains a Cascade
Setting followed by its current value. Six Cascade Set-
tings are displayed on the screen at one time.
Scroll through Cascade Settings using the UP or
DOWN keys.
Cascade Setting changes must be made on
the cascade Master. Cascade autodetec-
tion must be performed after making any
changes to a cascade Setting before the
change will take eect.
Stage Delay sets the time delay before enabling or
disabling a boiler in the Cascade System. The Stage
Delay begins once the Master boiler determines that
a boiler must be enabled to reach the setpoint or
when the Master boiler determines a boiler should
be disabled because of a decreasing load.
Adjust the Stage Delay duration using the LEFT or
RIGHT keys, then store the setting with the OK key.
Adjusting the Stage Delay will have the following ef-
fects:
• Increasing Stage delay
– Reaching the setpoint could take longer due to a
longer delay between enabling boilers.
– Overshooting the setpoint could occur due to
boilers staying on longer before being disabled.
• Decreasing Stage delay
– Overshooting the setpoint could occur due to
boilers being enabled quicker.
– Boilers will be disabled quicker, possibly increas-
ing boiler cycling and decreasing runtimes.
