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. |

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 |
|
|
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 |
| 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 |
|
|
Power Up Delay Inhibit: MIN:SEC | On Power up, the chiller will wait for the Power Up Delay |
