Cascade Screen:
The Cascade Screen provides the status of the cascade system.
Items that can be viewed on the Cascade Screen are as follows:
Water Heater Power Level Indicators - For each water heater
present in the cascade a power level indicator will be present
above its corresponding number. The level will rise and fall
indicating the approximate power level of the water heater.
The display box underneath each number will display “HW”
when that water heater is providing heat for a Hot Water
Generation call.
On Timer and Off Timer - The ON and OFF timers are
used to force each water heater in the cascade to have a
minimum on and off time to prevent short cycling.
Block Switch On Timer - Whenever a water heater is
commanded to start, the block switch on timer is started.
This provides a delay between the first ignition system and
the second ignition system inside the water heater. Once the
second ignition system is started, the timer is reset and the
next water heater is prevented from starting until the timer
times out. This process is repeated for each water heater in
the cascade.
Demand - Shows the status of the cascade. Displayed
items are:
No Demand - the Cascade leader has not received a
call for heat.
Hot Water Demand - the Cascade leader has received a
call for heat.

User Set Point + the Off Differential. 
Pump Delay - the cascade has satisfied a hot
water call and the hot water pump is running for a fixed
time.
Set Point - This is the set point of the cascade system. The heater
designated as the Leader will use this set point to determine the
power level required to bring the tank temperature to this point.
A default value of 50°F (10°C) is displayed when the Call for
Heat is inactive.

the display. It is displayed in a 24 hour format. Reference the
