Table 1 - Chiller Modes

Description
The chiller is not running and cannot run without intervention. Further
information is provided by the sub-mode:
Chiller is stopped by DynaView (or EasyView). Stop button command
cannot be remotely overridden.
Chiller is stopped by DynaView (or EasyView). Panic Stop (by
pressing Stop button twice) - previous shutdown was manually
commanded to shutdown immediately without a run-unload or
pumpdown cycle - cannot be remotely overridden.
The chiller is stopped by a diagnostic that requires manual
intervention to reset.
The chiller is currently being inhibited from starting (and running), but
may be allowed to start if the inhibiting or diagnostic condition is
cleared. Further information is provided by the sub-mode:
The entire chiller is stopped by a diagnostic that may automatically
clear.
The chiller is inhibited from starting by Low Condenser Temperature-
Inhibit is active below either -3.9°C (can be disabled with proper
freeze protection) or -18°C (limit set by design, cannot be disabled).
As an exception, this will not stop a chiller already running.
The chiller is inhibited from starting (and running) by an outdoor air
ambient temperature lower than a specified temperature - per user
adjustable settings and can be disabled.
The chiller is inhibited from starting (and running) by the "external
stop" hardwired input.
The chiller is inhibited from starting (and running) by command from
a Building Automation System via the digital communication link
(com 3 or com 5).
This is a transient mode - 15-min. max, and is only possible if the
chiller is in the Auto - Remote command mode. After a power up
reset, it is necessary to wait for valid communication from a BAS
(Tracer) to know whether to run or stay inhibited. Either valid
communication will be received from the BAS (Tracer), or a
communication diagnostic ultimately will result. In the latter case the
chiller will revert to Local control.
