Pump exercising will ensure that no pumps go for
long periods of time without running. Note that
automatic alternation can also provide this function-
ality. Pump exercising will only occur when the sys-
tem is started and in automatic operation. All pumps
which need exercising will exercise on startup. All
exercising events will be logged in the Exercise Log
shown in section 4.7.5.5. See Table 20 for a descrip-
tion of the Exercise variables.
