Appendix A: Boiler Operating Parameters
A. Overview
All TRIUMPH Series boilers are equipped with a microprocessor-based Honeywell control module called a “ MCBA”.
This control manages all boiler functions including flame supervision and modulation. A total of 46 field adjustable
parameters are stored in the memory of this control. These parameters determine the exact operation of the MCBA under
different conditions.
Triad has tried to program parameters into the MCBA at the factory that will result in satisfactory operation under most
conditions. Because all systems are different, however, there are a few situations where boiler operation may be en
-
hanced by adjusting a few of these parameters in the field. This section describes the parameters that may be changed and
the method for changing them.
Parameters are numbered from “1” to “42-2”. Parameters 1-4 are accessible by anyone. Parameters 5 through 42-2
may only be accessed by entering an access code. Parameters may be changed by either of two methods:
1) Using the keypad on the boiler
2) Using the GCI PC Interface Kit (PN 249905) available from Triad Boiler Systems, Inc..
In addition to being used to change parameters, both the key pad and the GCI Interface can be used to obtain informa-
tion about the boiler’s current status and operating history. For more information on the use of the GCI PC interface refer
to the instructions supplied with the kit.
WARNING
IMPROPER SETTING OF PARAMETERS CAN CAUSE UNRELIABLE OR UNSAFE OPERATION,
RESULTING IN PROPERTY DAMAGE, PERSONAL INJURY, OR LOSS OF LIFE:
• CHANGING PARAMETERS SHOULD ONLY BE ATTEMPTED BY A PROFESSIONAL HEATING
SERVICE TECHNICIAN.
• DO NOT CHANGE ANY PARAMETERS NOT DESCRIBED IN THIS MANUAL WITHOUT FIRST
CONSULTING THE FACTORY.
• BEFORE MAKING CHANGES, IT IS RECOMMENDED THAT INITIAL VALUES OF PARAMETERS
BE RECORDED SO THAT THEY CAN BE RESTORED IF OPERATION OF THE BOILER IS NOT AS
ANTICIPATED.
• AFTER CHANGING ANY PARAMETERS, CAREFULLY CONFIRM PROPER BOILER OPERATION
BEFORE LEAVING THE INSTALLATION SITE.
B. Entering the Access Code
Note: If access to only Parameters 1-4 is desired you do not need to enter the access code. Skip to Section (C).
1) With the boiler running, toggle the Mode key until you reach the (STBY) Standby mode.
2) Depress and hold the Step key and then quickly depress and hold the Mode key for 2 – 5 seconds until the display
reads (CODE). Release the Mode key, then the Step key. The display should show a ‘C’ followed by a random two digit
number.
3) Use the + or – keys to scroll to the number 05.
4) Press the Store key momentarily and watch for the display to blink twice. If the access code has been successfully
entered, the menu tree will be expanded to include the items shown inside the dashed lines in Figure A1.1. Access to
parameters 5 - 42 will be possible by following the instructions in Section C. After 15 minutes have passed without any
