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.

Chiller Level Mode
Top Level Mode Description
Stopped
The chiller is not running either circuit, and cannot run without intervention.
Stopped Sub Modes Description
Local Stop Chiller is stopped by the DynaView Stop button command- cannot be remotely overridden.
Immediate Stop
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.
No Circuits Available The entire chiller is stopped by circuit diagnostics or lockouts that may automatically clear.
Diagnostic Shutdown - Manual Reset The chiller is stopped by a diagnostic that requires manual intervention to reset.
Cond Pmp Strt Dly (Head Pres Ctrl) min:sec
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.
Chiller Level Mode
Top Level Mode Description
Run Inhibit
The chiller is currently being inhibited from starting (and running), but may be allowed to start if the
inhibiting or diagnostic condition is cleared.
Run Inhibit Sub Modes Description
No Circuits Available The entire chiller is stopped by circuit diagnostics or lockouts that may automatically clear.
Ice Building Is Complete
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.
Ice to Normal Transition
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.
Start(ing is)* Inhibited by BAS (Building
Automation System)*
Chiller is stopped by Tracer or other BAS system.
Start(ing is)* Inhibited by External Source The chiller is inhibited from starting or running by the "external stop" hardwired input.
Diagnostic Shutdown - Auto Reset The entire chiller is stopped by a diagnostic that may automatically clear.
Waiting for BAS Communications (to Establish
Operating Status)*
The chiller is inhibited because of lack of communication with the BAS. This is only valid 15 minutes
after power up.
Start(ing is)* Inhibited by Low Ambient
Temp(erature)*
The chiller is inhibited based on the outdoor air temperature.
Start(ing is)* Inhibited by Local Schedule The chiller is inhibited from starting based on the local time of day scheduling (option)
