2). If the button is subsequently pressed again prior to the expiration of the Bypass time,
the timer will reset to the initial value and resume counting down.
Priorities of Occupancy Control
Occupancy overrides are prioritized as follows (listed from highest to lowest):
• Wall Switch Input – Typically a physically operated switch used by occupants of room.
• Operator Command – A valid occupied command sent from system operator.
• Bypass Button – Button on Talon room sensor, also utilized by occupants of room.
• Occupancy Sensor – Locally connected or signal via the network.
• Occupancy Schedule – Sent from network.
Special Features
Outside Air Temperature Equipment Lockouts
If the outside air temperature falls below a configurable limit, the cooling DX compressors can
be disabled. If the temperature rises above a configurable temperature, the auxiliary and
perimeter heat can be disabled.
Source Temperature Compressor Lockout
The Predator can monitor the source water temperature to determine suitability for cooling or
heating. The minimum source temperature for heating and the maximum source temperature
for cooling can be configured to disable the DX compressor when the limits are reached.
Random Start
The Predator can be configured with a maximum start delay. Whenever the controller is
turned on, it will start randomly within the maximum start delay. This prevents all units
from operating at once.
Optional Functions
Duct Temperature Sensor
An optional duct temperature sensor may be connected to the Predator for the purpose of monitoring
he source temperature. This is useful for functions such as morning warm-up, when you want to be
sure warm air is being provided to the space. It is also beneficial as a troubleshooting aid to determine
space comfort issues.
Wall Switch
Space occupancy can be controlled via a maintained wall mounted switch. Rooms with varying
occupancy schedules (i.e. conference rooms, etc.) can use this device to control occupancy and the
lights with one switch.
Occupancy Sensor
An alternative method of controlling space occupancy is through an occupancy sensor. The
function of this sensor is similar to the wall switch, but eliminates user intervention by
automatically placing the room into occupancy mode when people are sensed in the space.
Additionally, if the scheduled is currently in the occupancy mode and the occupancy sensor
does not detect any people in the space, the room will go into an energy savings standby
mode, while still maintaining comfort.
