1. The decimal poin
t is fixed to the tenths place, but not transmitted. For example, a value of 1000 equals 100.0
2. The value is only writable when the program has been set to accept a BMS communication signal, see program
documentation for individual details
3. Refer to alarm chart for index number definition. Alarm index is only active when the active alarm value is equal to 1
4. This connection refers to the local boiler network required for Lead/Lag connectivity. Not all boilers will be available. For
