Force Modes
This screen applies to both types of AHU Controllers so it will only appear one time in
this manual.
Note: The Binary Input Contact only applies to the Zone Manager!
Both AHU controllers default to the Auto mode of operation
when first powered up. Any force modes entered will be
retained in non-volatile memory. The unit will resume the force
mode of operation anytime the power is cycled.
0) Auto
- Use internal schedules for Day/Night
Mode
1) Occupied - Forced to Continuous Day or Occupied
Mode
2) Night
- Forced to Continuous Night or
Unoccupied Mode. If the Forced Occupied
Binary Input Contact is closed, this mode
will override it to OFF. Use the Auto mode
programmed for continuous Unoccupied
operation if you want to use the Forced
Occupied Binary Input Contact.
3) Fan Only This is the mode that is active whenever
you see the Purge Cycle message being
displayed. It disables any heating or
cooling and forces all the boxes to move
their dampers to the full 100 percent open
position. You can use this mode anytime
you want to manually purge your building.
