Controls Interface
Ice Building The chiller is Building Ice, and will terminate on the Ice Termination Setpoint
based on the Entering Evap Water Temperature sensor.
Hot Gas Bypass Time Remaining: MIN:SEC The chiller is running in Hot Gas Bypass with the specified time remaining.
Top Level Mode Description
Running - Limit At least one circuit on the chiller is currently running, but the operation of the
chiller as a whole is being actively limited by the controls. The sub modes
that apply to the Running top modes may also be displayed along with the
following limit specific modes.
Sub Modes Description
Demand Limit The number of compressors allowed to operate is being limited to less than
the available number of compressors by either the BAS system or the front
panel demand limit setpoint.
Evaporator Temperature Limit The control algorithm takes action to avoid a nuisance trip when the leaving
water temperature is approaching the Leaving Water Temp. Cutout Setpoint.
Hot Start Limit The second compressor on a given circuit is being held off based on leaving
evaporator temperature.
Compressor Inhibit The KW limit binary input is open. The second compressor of each circuit
shall be prohibited from starting or running.
Top Level Mode Description
Shutting Down The chiller is still running but shutdown is imminent. The chiller is going
through a compressor run-unload.
Sub Modes Description
Evaporator Water Pump Off Delay: MIN:SEC The Evaporator pump is executing the pump off delay timer.
Top Level Mode Description
Misc. These sub modes may be displayed in most of the top level chiller modes
Misc. Sub Modes Description
Manual Evaporator Pump Override The evaporator water pump relay is on due to a manual command.
Diagnostic Evap Pump Override The evaporator water pump relay is on due to a diagnostic.
Manual Condenser Pump Override The condenser water pump relay is on due to a manual command.
Manual Compressor Control Signal Chiller capacity control is being controlled by DynaView or TechView.

Table 19 Circuit Level Operating Modes
Circuit Level Operating Modes: Description
Top Level Mode Description
Stopped The circuit is not running, and cannot run without intervention.
Sub Modes Description
Diagnostic Shutdown - Manual Reset The circuit has been shutdown on a latching diagnostic.
Front Panel Circuit Lockout The circuit is manually locked out by the circuit lockout setting - the
nonvolatile lockout setting is accessible through either the DynaView or
Tech Vi e w.
Top Level Mode Description
Run Inhibit The given circuit 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
Diagnostic Shutdown - Auto Reset The circuit has been shutdown on a diagnostic that may clear automatically.
Condenser Pressure Limit The circuit is being inhibited from starting due to high condenser pressure.
Top Level Mode Description
Auto The circuit is not currently running but can be expected to start at any
moment given that the proper conditions are satisfied.
Auto Sub Modes Description
No Circuit Sub-Modes
