Energy Management System
The following conditions must exist for the Energy
Management System to operate:
• OCCUPIED dip switch is up.
• Room Air Sensor (kit) is installed.
• Door Sensor (kit) is installed.
• Motion Sensor (kit) is installed.
The Energy Management System uses input from
the Door Sensor (kit) and Motion Sensor (kit) to
establish if the room is occupied or unoccupied.
When the Energy Management System has
established that the room is unoccupied, it uses
input from the Room Air Sensor (kit) and allows
the temperature of the room to lower to 68 °F (heat
mode) or raise to 78 °F (cool mode). When the
room becomes occupied, the Energy Management
System will return to thermostat-controlled
operation and will return the room to the
temperature set on the thermostat.

Door Sensor (kit)
The door sensor has a two-wire circuit that is
connected to the main board terminal strip. When
the door opens, the door sensor (switch) closes.
When the Energy Management System sees the
door sensor circuit close (door opened), the
Energy Management System will then check the
motion sensor circuit.
Note: The Energy Management System is
dependent on the Room Air Sensor, Motion
Sensor, and Door Sensor. If the Room Air Sensor,
Motion Sensor, and Door Sensor are not installed,
the Energy Management System will not operate.
The following conditions must exist
for the energy management system
to operate:
•
Occupied dip switch is up.
•
Room Air Sensor (kit) installed.
•
Door Sensor (kit) installed.
•
Motion Sensor (kit) installed.
When the door opens, the
unit will check the motion sensor.
Unit switches to Room Air
Sensor control. Unit will lower
temperature of room to 68 ˚F
(heat mode) or raise the
temperature of room to 78 ˚F
(cool mode).
Unit continues to
be controlled by
thermostat.
No motion
detected by
motion sensor.
