Chilled Water Setpoint and Source/Evap Leaving
Water Temp (Standard Report)
Chilled Water Setpoint [source]:
Evap Leaving Water Temp:
This is the actual setpoint currently in use by the
chiller. The "source," from where it is derived, can be
either External, Tracer or Reset (meaning reset is
enabled); otherwise the source is not displayed and
Front Panel setoint source is implied.
If the chiller is in the ice making or ice making
complete state, the following display is substituted for
the above display:
Ice Termination Setpt [source]:
Evap Entering Water Temp:
where source, if displayed is Tracer; otherwise it's
the Front Panel.
NOTE: The setpoint source may change
automatically from the implied "Front Panel "(no
source displayed) to "Tracer" if Tracer is
communicating a chilled water setpoint to the chiller.
The only way to override Tracer-communicated
setpoints is through the operator setting menu
(global setpoint override).
