Pump Control Mode
Sets the control algorithm used to trip the relay.
See
Pump Control Mode 2.7.1.4.
on page 151 for descriptions of each.
Service Ratio Pump 1
Selects pump usage based on the RUN time ratio rather than last used.
This parameter displays only if a Service Ratio algorithm is selected for Pump Control
Mode.
Service Ratio Pump 2
Selects pump usage based on the RUN time ratio rather than last used.
This parameter displays only if a Service Ratio algorithm is selected for Pump Control
Mode.
Run Time Relay 2
Set the amount of time that pump Relay 2 has run, defined in hours.
Use the default value for new pumps, or set this value for existing pumps with
accumulated run time. (This parameter displays only if a Service Ratio algorithm is
selected for Pump Control Mode.)
Run Time Relay 3
Set the amount of time that pump Relay 3 has run, defined in hours.
Use the default value for new pumps, or set this value for existing pumps with
accumulated run time. (This parameter displays only if a Service Ratio algorithm is
selected for Pump Control Mode.)
