Boiler01RuntimeLow16

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##Runti

meLow16

Example

Boiler01Runtime =

(Boiler01RuntimeHigh16 * 65536) +

Boiler01RuntimeLow16

Boiler01 = Master

Boiler02 = Member01
