IR5 (Infrared)
Table 2 e528 IR5 Characteristics
Performance IR5
Indoor Range Up to 80ft
IR Data Rate 2500 bps
The IR Eye5 works within INNCOM's System-5 protocol and can be used in a fluorescent light environment.
However, it may be subject to interference from plasma televisions, and care must be taken in situating the device
if a plasma television is present.

Installation Requirements

Location: The e528 must be located on a partitioning interior wall, approximately 1.5 m (5 ft) above the floor, in a
site of average temperature. It is important to ensure that the thermostat is located away from direct sunlight or
radiant heat, air discharge grills, stairwells, outside doors, steam or water pipes, warm air stacks,
unheated/uncooled areas, or sources of electrical or radio interference. The unit should not be placed on an outside
wall or behind a door. It is essential that the e4 is mounted flush to the wall and mounted level in both the horizontal
and vertical planes; incorrect mounting can degrade IR, PIR, and temperature measurement performance.
Installation Requirements for e4 equipped with PIR Motion Detection
The e4 thermostat can be equipped with a PIR detector to augment the energy management scheme by detecting
motion in the guestroom. Consider the PIR's view angle, range characteristics, and mounting position to ensure
proper coverage. Figure 3 below shows the ranges of the flat and standard PIRs.
