SMART SYSTEM control module
Access modes
User
The user can adjust the space heating target temperature
and the tank target temperature (if a tank sensor is used)
by using the UP and DOWN buttons (FIG. 7-1) at any time
during normal operation. By entering the USER code (0704),
the user can also change temperature units, time and date,
and night setback settings. In User Mode, the following
parameters can be viewed but not changed:
• Boiler outlet water target temperature in DHW Mode
• Appliance model number
• Software version
• Total operating hours
• Total cycles
Installer
Most parameters are available only to the installer, accessible
only by entering the installer access code, see the Copper-fin
II Service Manual.
Saving parameters
(reference the Parameter Table
in the Copper-fin II Service Manual)
To save parameters and exit programming:
Press the ENTER/RESET button, then the MENU/EXIT
button 3 times.
To keep parameter settings only for a current operating
cycle:
Press the MENU/EXIT button 3 times after making all
desired parameter changes.
To enter a parameter and continue programming:
Press the MENU/EXIT button 1 time to return to the
parameter listings; press again to return to the menu listings.
Remember to press the ENTER/RESET button when finished
programming in order to save the changes made.
See the Copper-fin II Service Manual for a detailed description
of parameters and access modes.
Viewable and changeable control
parameters
A: General
A1: 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
A1
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.
A2: 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 unit is first installed or any time
the unit has been powered off for more than 30 days. To set
the clock, parameter
A2
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 = Monday, 2 = Tuesday, etc.), hh
= hour (24 hour time; 2:00 PM = 14:00), mm = minutes.
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.
A3: 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 unit. When a new software version becomes available, the
existing control can be replaced with a new control to update
the software.
A4: 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
A4
. The default is °F.
A5: SH Night setback offset
Once the internal clock has been set correctly, the SH night
setback feature can be used to program a lower set point. The
value of this parameter will be subtracted from the normal set
point to determine the set point used during night setback.
This parameter can be changed by the user or the installer
by accessing parameter
A5
. The temperature range for this
parameter is 0°F to 90°F (50°C). The feature is turned off with
a setting of 0°F. The default value is 0°F.
