P191 Demote Pumps.
When an efficiency alarm is being used, this parameter will determine if a
pump is to be demoted to the last pump in the duty cycle on activation of
the alarm. When Demote Pump is enabled and the efficiency alarm is
activated after the predetermined Persist Count (P190) the pump duty will
default to a fixed duty regime with the inefficient pump being set to the last
pump in the cycle which will be called to start if the level reaches the on
point for that pump. A pump which has been demoted will be indicated by
the relevant “pump” relay LED “flashing” RED.
