G. SYSTEM TEST
The System Test feature allows the installer or service
person to make the control operate at Low Power,
Ignition Power, or Maximum Power. This is a setup and
troubleshooting tool that allows the installer or service
person to obtain combustion readings or observe
operation.
To operate the boiler under System Test, enter the
installer menu by holding down the “Menu” and “Select”
keys simultaneously for 10 seconds. Then press the “
M
”
key until the “
” indicates System Test. Press the
“Select” key to choose the menu. The default setting for
System Test is “Off”. Choose the desired setting and press
“Select” again to initiate the test.
Once the System Test is initiated, the service person may
exit the menu screen by pressing the “Menu” key until the
status screen is displayed. “System Test” will be displayed
at the top of the display screen until the operator exits the
system test mode.
H. STATUS & FAULT HISTORY
1.
General
The
P
URE
F
IRE
boiler control allows the installer to view
the status of several key parameters. In addition, it
provides details in English about the last 15 Blocking
Errors and the last 15 Lockout Faults.
The Status and Fault History can be viewed from the
Installer Menu. The Installer Menu Structure is shown
in Appendix C of this manual.
This menu can be accessed by pressing and holding
the “Menu” and “Select” keys simultaneously for 10
seconds. The “
” indicator will be indicating
“Status”. Press the “Select” Key to access this feature.
2.
Status
Current Supply Setpoint:
The first screen indicates
the current supply setpoint. In CH Mode 0, 3, and 6
this will be the setpoint selected from the User Menu.
If the boiler is operating an outdoor reset mode (CH
Mode 1 or 2) this value will be the target setpoint
temperature calculated based on the outdoor
temperature. In CH Mode 4, this value will
correspond to the 0-10 V signal input.
Fan Speeds:
By pressing the “
M
” key the operator
can view the current fan speed and the low power fan
speed. The current fan speed will be directly
comparable to the current input rate. The low power
fan speed is a factory preset software parameter that
indicates the minimum input to the boiler.
Pressing the “
M
” key again displays the ignition and
high power fan speed. Both of these are factory preset
software parameters that cannot be changed by the
installer. The ignition speed is the speed at which the
blower runs during the ignition period. The high
power fan speed corresponds to the maximum input
to the boiler.
Flame Signal/Failures:
Pressing the “
M
” key again
will display the Flame Signal/Failures Screen. The
flame signal is an indication of combustion stability of
the burner. If this value is below 1.7 µA (microampere)
the control will close the gas valve and the burner will
recycle through the ignition cycle. The flame signal
should be above 5.0 µA in normal operation.
If the control loses its flame signal 3 times during one
call for heat, it will lock out the control indicating,
“Flame Failure”. The number of flame failures in the
history of the control is displayed below the flame
signal on the menu screen.
The
P
URE
F
IRE
boiler control uses dual flame sensing to
minimize nuisance lockouts. See Section 10,
Troubleshooting, to address flame failure issues.
Ignition Attempts:
Once again, press the “
M
” key
to advance to the Ignition attempts status screen. This
screen displays the number of successful and failed
ignition attempts that have been made by the control.
If excessive ignition attempts are shown on this screen,
reference Section 10, Troubleshooting.
Boiler Run Time:
Pressing the “
M
” key again
advances the menu to show Boiler Run Time. This
indicates the number of hours that the boiler has
operated under CH or DHW demand. The values are
rounded to the nearest hour.
3.
Fault History
The following sections provide instructions on how to
access the fault history that is stored on the control.
The
P
URE
F
IRE
control stores the last 15 blocking errors
and the last 15 lockout errors and allows the installer
or service person to review the fault history of the
control.
Section 10, Troubleshooting, provides detailed
descriptions and troubleshooting approaches to the
errors reported by the control.
Last Block:
By continuing to press the “
M
” key, the
status menu displays the following screen. The last
block indicates the last blocking error (error that does
not cause a lockout). The first number indicates the
time interval in minutes since the previous error. The
#EXX represents the Error Code which can be
referenced in Section 10, Troubleshooting. The last
two lines provide an English description of the error.
Last Lock:
The next screen accessed by pressing the
“
M
” key provides information about the last lockout
error. Again the first number represents the interval
since the last lockout error. #AXX represents the Fault
Code which can be referenced in Section 10,
Troubleshooting. Again the last two lines provide an
English description of the fault.

BOILER CONTROL: INTERNAL WIRING & OPERATION
Be sure to set the System Test parameter back to
“Off” before leaving the installation. Otherwise,
problems with cycling or insufficient heat may occur.
