Maximum Cascade Set Point
This parameter determines the set point used by the individual
water heaters in a Cascade. When a water heater is commanded
to fire by the Leader water heater, it will attempt to achieve
this temperature at its outlet. The Leader water heater will
limit the modulation of the water heaters in order to hold the
temperature at the tank sensor to the user set point. If any of the
water heater outlet temperatures reach the maximum cascade
set point, the water heater will then modulate down on its own
in order to keep its outlet temperature within the maximum
cascade set point. Therefore, this parameter can be used to limit
the outlet temperatures of all the water heaters in a Cascade.
This parameter is adjustable by the installer by accessing the
Maximum Cascade Set Point parameter. The temperature
range of this parameter is 32° (0°C) to 190°F (88°C). The
default maximum cascade set point is 185°F (85°C).
Minimum On/Off Time
In order to prevent units in a Cascade from short cycling,
this parameter defines the minimum ON and OFF time for
each unit. The installer can adjust this time by accessing the
Minimum On/Off Time parameter. The minimum setting is 0
seconds and the maximum setting is 10 minutes. The default
is 30 seconds.

Minimum Next On Time
In order to reduce the risk of temperature overshoot with a
Cascade, this parameter defines the minimum time delay from
starting one unit until the next unit may be started. The installer
can adjust this time delay by accessing the Minimum Next On
Time parameter. The minimum setting is 0 minutes and the
maximum setting is 10 minutes. The default is 60 seconds.
