Manual Control
A user may manually control outputs to check operation of
components when Manual Control is set to ManCtrl. When
Manual Control is set to ManCtrl, the unit is disabled and
the unit is shut down in the normal manner if it is operating.
Outputs listed in the Manual Control menu of the Keypad/
Display section can then be controlled directly until Manual
Control is set to Normal.
NOTE: Manual Control will be set to Normal automatically
after 240 minutes so that a person could not put the
unit into Manual Mode control and walk away from the
unit and let it run at the manual settings.
When Manual Control is set to Yes, the Control Mode is set to
Off so that the unit will not restart automatically.
When Manual Control is set to Normal all digital outputs in the
Manual Control menu are set to Off and all the analog outputs
are set to 0.0% so that all outputs are in the Off or minimum
position when Manual Control is set to ManCtrl.
All alarms except those listed below are overridden during
Manual Control.
During manual control, the unit will respond in the normal
manner to the following alarms.
• Emergency Stop Fault
• Duct High Limit
• High Return Temperature
• High Discharge Temperature
• Low Discharge Temperature
• High Pressure - Cooling and Heating*
• Low Pressure - Cooling and Heating*
• Inverter and Standard Compressor High Discharge
Temperature*
• Inverter Compressor High Current*
• Inverter Compressor Board Temperature*
• High and Low Pressure Differential*
* The unloading routines normally used before shut down are
not active in manual modes. These safeties will immediately
shut down the unit.
