----- The following registers are available starting in firmware version 2.0 -----
Boiler (1 – 16) supply temperature (if
available). See BoilerStatus2 to
determine if the sensor is present.
Boiler01 = Master
Boiler02 = Member01
…
Boiler16 = Member15
Boiler (1 – 16) return temperature (if
available). See BoilerStatus2 to
determine if the sensor is present.
Boiler01 = Master
Boiler02 = Member01
…
Boiler16 = Member15
Boiler (1 – 16) Cycles High (Upper) and
Low (Lower) 16 bit counters. To get the
actual cycle count for any given boiler
(##), the high and low 16 bit counters
must be combined (concatenated) into
a single 32 bit counter as:
Boiler##CyclesHigh16:Boiler##CyclesL
