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
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.
Start Inhibited by BAS Chiller is stopped by Tracer or other BAS system.
Start 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 The chiller is inhibited because of lack of communication with
the BAS. This is only valid 15 minutes after power up.
Start Inhibited by Low Ambient Temp The chiller is inhibited based on the outdoor air temperature.
Chiller Level Mode
Top Level Mode Description
Auto The chiller is not currently running but can be expected to
start at any moment given that the proper conditions and
interlocks are satisfied.
Auto Sub Modes Description
Waiting For Evaporator Water Flow The chiller will wait a user adjustable time in this mode for
evaporator water flow to be established per the flow switch
hardwired input.
Waiting For A Need To Cool The chiller will wait indefinitely in this mode, for an evaporator
leaving water temperature higher than the Chilled Water
Setpoint plus some control dead-band.
Waiting For A Need To Heat For water cooled (CGWN), the chiller will wait indefinitely in
this mode, for a condenser leaving water temperature lower
than the Hot Water Setpoint plus some control dead-band. For
a reversible (CXAN) the chiller will wait indefinitely in this
mode, for an evaporator leaving water temperature lower than
the Hot Water Setpoint plus some control dead-band.
Power Up Delay Inhibit: MIN:SEC On Power up, the chiller will wait for the Power Up Delay
Timer to expire.
