Bypass Mode
During unoccupied periods, an occupant can put the Predator in the bypass mode by pressing the
bypass button on the room temperature sensor. This causes the controller to operate exactly as in
the occupied mode, for an adjustable amount of time.
Standby Mode
Standby mode applies separately adjustable temperature and ventilation setpoints. These may be
adjusted to conserve energy, but allow quicker recovery compared to the unoccupied mode.
Otherwise, operation is the same as the unoccupied mode.
Morning Warmup
During unoccupied periods, if the Predator is commanded to warmup mode, it applies the occupied
heating setpoint (to restore comfort conditions) and the unoccupied minimum flow (because
occupants are not present). Operation of each HVAC device, in response to heating demand is
selectable in the warmup mode. The behavior of perimeter heat, the primary air damper and the
reheat coil may be individually configured. They may be forced on, locked out, modulated or cycled
according to the required sequence.
Pre-cool
During unoccupied periods, if the Predator is commanded to pre-cool mode, it applies the occupied
cooling setpoint (to restore comfort conditions) and the unoccupied minimum flow (because the
occupants are not present).
The reheat coil is off.
Perimeter heat is off.
Calibrate (Test)
The Predator closes the primary air damper and calibrates the air flow sensor. Once commanded
to test mode, the controller remains in this mode (even if it is commanded to another mode) until
the recalibration is complete. This process takes approximately two times the damper motor travel
time.
The reheat coil is off.
If perimeter heat is active, it continues to operate.
Off
The Predator closes the primary air damper, and turns off the reheat coil, and turns off perimeter
heat.
