Description
The main processor is going through reset
No chiller sub-modes.
The chiller is not running either circuit and cannot run without intervention. Further
information is provided by the sub-mode:
Chiller is stopped by TD7 Stop button command– cannot be remotely overridden.
Chiller is stopped by the TD7 Panic Stop (by pressing Stop then Immediate Stop in succession) – previous
shutdown was manually commanded to shutdown immediately.
The entire chiller is stopped by circuit diagnostics or lockouts that may automatically clear.
Chiller is running to provide a chilled water temperature per the active chilled water setpoint (may be as
arbitrated from various sources). (For cooling only units, this mode may be suppressed.)
The chiller is inhibited based on the outdoor air temperature.
Note: You can also access the Chiller Operating Modes
screen from the chiller status button in the upper
left corner of the screen.
