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.

Set Point Met - the tank temperature has met the

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.

Time - The time is displayed in the upper right-hand corner of the display. It is displayed in a 24 hour format. Reference the night setback parameters on page 21 for information regarding adjusting the date and time.
