AERCO BMS II BOILER - Manual (Page 107)

I-1
APPENDIX I
_____________________________
BOILER START AND BOILER STOP LEVELS
The BMS II Configuration Menu contains options for the Boiler (BLR) Start and Boiler Stop Levels. The
default settings for these options are as follows:
• Boiler Start Level:
20%
• Boiler Stop Level:
16%
In order for the BMS II to properly control the boilers in the Boiler Plant, the corresponding Start and Start
levels must be entered in the BMS II Configuration Menu for the type of AERCO boilers being controlled.
For C-More controlled Benchmark or KC1000 Boilers, the Required Start and Stop Levels are listed at the
end of Chapter 3 in the appropriate Boiler O & M Manual. If the correct O & M Manuals are not available
at the installation site, the correct values can be verified by accessing the Calibration Menu in the C-More
Boiler Controllers.
For Modulex Boilers, the corresponding Start and Start Levels for each Boiler Model are listed in the
following Table.
MODULEX BOILER START/STOP LEVELS
MODULEX
MODEL
NUMBER OF
MODULES START LEVEL STOP LEVEL
MLX-303 2 17% 15%
MLX-454 3 12% 10%
MLX-606 4 9% 7%
MLX-757 5 7% 5%
MLX-909 6 6% 4%
MLX-1060 7 5% 3%
When the Boiler Plant being controlled by the BMS II is comprised of a combination of AERCO Boiler
types and sizes, the following guidelines should be used:
• Modulex Boilers: For different sizes of Modulex Boilers, use the Lowest Start/Stop levels for the
Modulex Boilers included in the plant.
• C-More Controlled Boiler: For different sizes of C-More controlled Boilers, use the highest Start/Stop
levels for the Boilers included in the plant.
• Modulex & C-More Controlled Boilers: When a mix of Modulex and C-More Boilers is include in the
heating plant, use the C-More controlled Boiler Start/Stop levels.
