Room Air
Sensor
Motion Sensor (kit)
The motion sensor has a 2-wire circuit that is
connected to the main board terminal strip. The
motion sensor is an electronic sensor that, when
motion is sensed, closes a switch (internal to the
sensor), completing the motion sensor circuit.
After the Energy Management System has seen
the door sensor circuit closed (door opened), it will
check the motion sensor circuit. If the Energy
Management System sees the motion sensor
circuit closed (no motion detected by the sensor),
it will then check the temperature being reported
by the room air sensor. If the Energy Management
System sees the motion sensor circuit open
(motion detected by sensor), the unit will continue
to be thermostat-controlled.
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.

Room Air Sensor (kit)
The room air sensor is a thermistor with a
negative coefficient (as temperature rises,
resistance goes down). The sensor has a 2-wire
circuit that is connected to the main board terminal
strip.
The room air sensor is used for Temperature
Limiting and for the Energy Management System.
When the Energy Management System sees the
door sensor circuit close and then the motion
sensor circuit close (room unoccupied), the
Energy Management System will ignore the
thermostat and check the temperature reported by
the room air sensor. Based on the input from the
room air sensor, the Energy Management System
will allow the temperature of the room to lower to
68 °F (heat mode) or raise to 78 °F (cool mode).
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.
