Chiller Operating Mode

The machine-operating mode indicates the operational status of the chiller.
A subscreen with additional mode summary information will be provided
by selection of an additional information icon (>>). The operating mode line
will remain stationary while the remaining status items scroll with the
up/down arrow keys.

The chiller is not running either circuit, and cannot run without intervention.
Chiller is stopped by the DynaView Stop button command- cannot be remotely overridden.
Chiller is stopped by the DynaView Immediate Stop (by pressing the Stop then Immediate Stop
buttons in succession) - previous shutdown was manually commanded to shutdown immediately.
The entire chiller is stopped by circuit diagnostics or lockouts that may automatically clear.
The chiller is stopped by a diagnostic that requires manual intervention to reset.
Only possible when Condenser Head Pressure Control option is enabled and the condenser pump is
being manually commanded to run - this wait may be necessary due to the Head Pressure control
device's stroke time.
The chiller is currently being inhibited from starting (and running), but may be allowed to start if the
inhibiting or diagnostic condition is cleared.
The entire chiller is stopped by circuit diagnostics or lockouts that may automatically clear.
The chiller is inhibited from running as the Ice Building process has been normally terminated on the
evaporator entering temperature. The chiller will not start unless the ice building command (hardwired
input or Building Automation System command) is removed or cycled.
The chiller is inhibited from running for a brief period of time if it is commanded from active ice
building mode into normal cooling mode via the ice building hardwired input or Tracer. This allows time
for the external system load to "switchover" from an ice bank to the chilled water loop, and provides for
a controlled pull down of the loop's warmer temperature. This mode is not seen if the ice making is
automatically terminated on return brine temperature per the mode below.
Chiller is stopped by Tracer or other BAS system.
The chiller is inhibited from starting or running by the "external stop" hardwired input.
The entire chiller is stopped by a diagnostic that may automatically clear.
The chiller is inhibited because of lack of communication with the BAS. This is only valid 15 minutes
after power up.
The chiller is inhibited based on the outdoor air temperature.
The chiller is inhibited from starting based on the local time of day scheduling (option)
