4. Next, scroll to the
INTERNAL SETPT
menu option. The second line of the display will show the
current Internal Setpoint temperature (°F) stored in memory.
5. Press the
CHANGE
key. Set the
INTERNAL SETPT
temperature to 180°F using the ▲ and ▼ arrow
keys. When set, store the change by pressing the
ENTER
key.
6. Turn on the BMS II by pressing the
ON/OFF
key. The ON indicator will light and the boiler plant will
start to operate.
7. Using the
MENU
key on the BMS II, scroll to the OPERATING MENU. The first line of the display will
show the Header Temperature. The second line of the display will show the Firing Rate % and the
number of Units (boilers) firing.
8. When all boilers have reached at least a 55% firing rate, any boilers that have not started have not
been identified by the BMS II.
9. Remember that in the Sequential mode, the BMS II turns boilers on in 30-second intervals. Therefore,
in a 6-boiler plant, with five boilers operating at 55% capacity, a boiler that has not started after 3
minutes has not been recognized. In parallel mode, all boilers will start at the same time.
10. This completes the System Test. Return the
HEADER SET MODE
and
INTERNAL SETPT
settings to
their previously stored values.
11. If the System Test is not completed successfully, refer to the troubleshooting procedures in this
manual (Chapter 5) and the applicable O & M Manuals for the boilers included in the boiler plant. If
the problem can still not be resolved, contact AERCO at 1-800-526-0288.
CAUTION
Monitor the HDR TEMP reading to ensure it is not ramping up too
high. If it is, press the ON/OFF key of the BMS II to shut down the
boilers. Remember that the boiler outlet temperature may be
higher than the BMS II header temperature.
