Viewable and changeable control parameters
A: General
Boiler model
The control will display “Armor Heater” as the model number
because the same control is used on several models. This will
be displayed when parameter A1 has been accessed. This
parameter is not changeable.
User code
The User Code allows the user to access and change a limited
number of control parameters. The access code can be
changed by the user or the installer to a code of their
choosing. To change the code, parameter A2 must be
accessed. The default code is 0704. The code can be changed
one digit at a time by using the arrow keys on the display.
Date and time
The control uses an internal clock for the night setback
feature and for logging of events. For these features to work
correctly, the clock must be set when the water heater is first
installed or anytime the water heater has been powered off for
more than 30 days. To set the clock, parameter A3 must be
accessed. The date and time are displayed as “YY:MM:DD W
hh:mm”. YY = year, MM = month, DD = date, W = day (1 =
Sunday, 2 = Monday, etc.), hh = hour (24 hour time;
2:00 PM = 14:00), mm = minutes.
Software version
The software version allows the user to view the software
version in use by the control. This software controls the
operation of the water heater. When a new software version
becomes available, the existing control can be replaced with a
new control to update the software.
Temperature units
The control can be configured to display temperature in
either °C or °F. This parameter can be changed by the user or
the installer by accessing parameter A5. The default is °F.
Night setback temperature
Once the internal clock has been set correctly, the night
setback feature can be used to program a lower water
temperature set point for water heating. This feature is only
used when a tank sensor is used. This parameter can be
changed by the user or the installer by accessing parameter
A6. The temperature range for this parameter is 32°F to
140°F. The feature is turned off with a setting of 32°F. The
default value is 32°F.
Night setback times
If parameter A6 is set to anything other than 32°F, the night
setback feature becomes active. This will require start and
stop times to be programmed for the days that reduced
temperatures are required. These times can be changed by
the user or the installer by accessing parameter A7. Each day
of the week (Sunday through Saturday) will have an on and
off time.
Example: Monday ON: 22:30, Tuesday OFF: 6:45. If you
wish to skip a day and have no night setback, leave the on and
off times the same. The default times for each day will be
00:00 (midnight).
B: Not used
C: Data logging
Total hrs. run
The total hrs. run parameter shows the total number of hours
the water heater has been in the DHW firing position. This
parameter can be viewed by the user and the installer by
accessing parameter C1.
Ignition attempts
The ignition attempts parameter shows the total number of
times the water heater has attempted to fire. This parameter
can be viewed by the user and the installer by accessing
parameter C2.
Show last 10 errors
The control will log the 10 most current errors with the date
and time the error occurred. This parameter can be viewed
by the user and the installer by accessing parameter C3.
CAUTION
Before changing parameters, note the
settings so that the unit can be returned to
its original operating parameters.
NOTICE
The internal clock does not adjust for
Daylight Savings Time and therefore,
will require a manual adjustment.
