Monitor the HDR TEMP reading to ensure it is not ramping up too
high. If it is, press the ON/OFF key of the ACS to shut down the
boilers. Remember that the boiler outlet temperature may be higher
than the ACS header temperature.
NOTE
When a Building Automation System (BAS) is connected to monitor
the ACS, ensure that the RS232 Menu is configured properly.
If the boilers connected to the ACS are to be monitored by the BAS,
ensure that the MODBUS PASS THRU option in the RS232 Menu is
enabled.
