12. This process occurs throughout the operating range
of the chiller. At “in-between” stages of chiller
capacity and demand balancing, the modulating
valves maintain a constant leaving fluid
temperature across all operating modules.
13. The microprocessor will rotate to a new primary
module each week to equalize the running time
among the modules.
14. When a redundant primary microprocessor
controller is provided on a chiller module, the
redundant primary microprocessor will, without
downtime and without any operational deficiency,
perform the primary microprocessor functions
should it fail. All operational sequences shall be
uninterrupted and uninhibited should the primary
microprocessor fail.
