The maximum number of boilers available to
fire.
0 - 16

SystemReturnTemp
16 bit signed
---
The system return temperature (if available).
See BoilerStatus4 to determine if the sensor
is present.

SystemFlowHigh16
32 bit unsigned
0.01
Boiler SystemFlow High (Upper) and Low
(Lower) 16 bit registers. To get Boiler
SystemFlow High (Upper) and Low (Lower)
16 bit registers. To get the actual
SystemFlow, the high and low 16 bit
registers must be combined (concatenated)
into a single 32 bit counter as:
SystemFlowHigh16: SystemFlowLow16
Example
SystemFlow = ((SystemFlowHigh16 * 65536)
+ SystemFlowLow16) * 0.01
This value is either the system flow meter
reading or the value written to the
BMSFlowRateGPM register by the BMS.
0-1500 GPM
