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.

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.

Occupancy Sensor

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.

Analog Damper Actuator

The Predator supports use of a Siemens OpenAir

™

GMA161.1U (or GMA161.1P – plenum

type) or similar damper actuator when 0-10 VDC position control is desired.

Perimeter Heat

This application also supports the optional control of perimeter heat. The algorithm supports

analog, 3-point floating, pulse width modulation, and on/off control of the perimeter heat.

Perimeter heat operates independently of terminal airflow or the current state of the terminal
