Configuration of the cascade
When installed in a Cascade system, the individual controls
must be programmed for cascade operation. This is
accomplished by accessing the control parameters.
Input the Installer code as described in the Armor Water Heater
Service Manual. Once the control parameters have been
accessed, use the DOWN arrow key to select the H Control
Mode parameters. Press the ENTER key to access these
parameters. Use the UP arrow key to access parameter H2 SH
Source. Press the ENTER key to access this parameter. Use the
DOWN arrow key to select Cascade. Press the ENTER key to
program this into the control.
Press the UP arrow key to select the parameter H3 WHR
Address. Press the ENTER key to access this parameter. Each
unit in the Cascade system must be programmed with its own
address. The water heater designated as the Leader will have an
address of 0. The remaining water heaters in the Cascade will be
Members and have addresses from 1 - 7. Use the UP and
DOWN arrow keys to select the appropriate address. Press the
ENTER key to program this into the control.
Press the MENU key twice to exit the control parameters. Repeat
this procedure for all water heaters in the Cascade, designating
the Leader control and the Member controls.
Set clock
The SMART SYSTEM control has a built-in clock that it
uses for its night setback feature and for logging events.
This clock must be set when the water heater is installed,
and anytime the water heater has been powered off for
more than one month. Use the following procedure to set
the clock:
1. Press and hold the MENU key for a least 5 seconds.
2. The display changes to ready “ENTER MENU CODE”,
with four (4) zeros below it.
3. Change the zeros to match the user code (factory set at
“0704”). Use the UP and DOWN keys to increment or
decrement the flashing digit, and the NEXT and
PREVIOUS keys to select which digit flashes.
4. Press the ENTER key.
5. The display changes to read USER CODE for a few
seconds, then displays a menu.
6. Press the ENTER key.
7. Press the UP key twice to display “A3 DATE AND
TIME”.

hh: hour (24 hour time; e.g., 2:00 PM = 14:00)
W:
day of the week (1 = Sunday, 2 = Monday,
3 = Tuesday, etc.,)
DD: date

Use the UP and DOWN keys to increment or decrement the

select which number flashes.

Mode.

will require a manual adjustment.
