Bypass Mode
If enabled (through stptDialEn) and the Bypass button on the Predator room sensor is
pressed, the controller will be placed in the Bypass mode for the amount of time
specified by the controller’s configuration parameters (default 60 min. – see Table 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):
• 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/Wall Switch – Locally connected or signal via the network.
• Occupancy Schedule – Sent from network.
Optional Functions
Room Temperature Sensor Sharing
The Predator Room Temperature Sensor may share its value with other controllers
on the LonTalk network via a network binding. This is most commonly done when
multiple terminal units serve a room or area.
Duct Temperature Sensor
An optional duct temperature sensor may be connected to the Predator controller for
the purpose of monitoring the source temperature. This is useful for functions such as
morning warmup, when you want to be sure warm air is being provided to the box, or
as an aid in troubleshooting space comfort problems.
Occupancy Sensor/Wall Switch
An optional maintained contact wall switch may be used to control the occupancy mode of
a room. Rooms with variable occupancy (conference rooms, etc.) can use this device to
control occupancy and the lights with one switch.
Another useful option is to utilize an occupancy sensor to control the occupancy
mode of the Predator controller. The function of this device would be similar to the
wall switch above, but an occupant entering the room would not perform any manual
action to put the room into occupied mode. If the schedule is in the occupied mode
and the occupancy sensor does not detect people in the room, the room will go into
the standby mode enabling energy savings while maintaining occupant comfort.
Lighting Control Relay
The Predator controller can selectively operate with maintained contacts or pulsed
contacts to switch lighting control relays. This is useful in those instances where
lighting control is desired, but a lighting control panel with a LonTalk interface is
either not present or not feasible.
Analog Damper Actuator
The standard application is setup to use a Siemens GDE or GLB, or similar 3-point
floating actuator for air volume control. Alternatively, A Siemens Open Air
TM
or similar
damper actuator could be utilized if 0-10 VDC modulating control is desired.
