Boiler01RuntimeHigh16
16 bit
unsigned
---
Boiler (1 – 16) Runtime seconds
High (Upper) and Low (Lower) 16
bit counters. To get the actual
runtime for any given boiler (##),
the high and low 16 bit counters
must be combined (concatenated)
into a single 32 bit counter as:
Boiler##RuntimeHigh16:Boiler##R
untimeLow16

Boiler01Runtime =
(Boiler01RuntimeHigh16 * 65536)
