4.1.14 flow setup
Parameter: flow source (read only)
Options: Function:
sensor Indicates that the flow is obtained from a sensor.
This parameter is automatically set based on the
vfd type selected on the pump setup screen
sensorless Indicates that the flow is obtained from sensorless
vfds. This parameter is automatically set based on
the vfd type selected on the pump setup screen
Parameter: flow range
Range: Function
0 - 20000 Indicates the range of the flow sensor in engineer-
ing units. This value corresponds to the sensor’s
20mA output. Note: this parameter only appears
when flow source is sensor
Parameter: flow limits source
Options: Function:
local Select local to manually setup the number of
available chillers or boilers and enter flow limits
of each unit on the corresponding chiller popup
screens. ips4000 uses digital inputs to determine
which chillers/boilers are enabled.
bas Select ‘bas’ for automatic selection of chiller/boil-
er minimum and maximum flow obtained from bas
Parameter: no of chillers/boilers
Range: Function:
1-6 Indicates number of chillers/boilers installed in the
system.
