E529 Product Guide

Application
In its most basic form, the battery powered e529 functions as a programmable
DDC thermostat, automatically adjusting fan speeds and valves to achieve set
temperature (Note: Guests can manually select heat or cool by pressing the
OFF/AUTO button and cycling through OFF, AUTO, HEAT and COOL). The
e528 is also an “intelligent” device capable of linking ancillary sensors and
serving as an information gateway. For example, coupled with a magnetic door
switch (wired or wireless), motion detectors, and other devices, the e528
becomes the brain of a highly effective Energy Management System (EMS)
application, communicating EMS information requirements to central servers. It
comes standard with five relays and can be equipped with a radio frequency
(RF) transceiver and Passive Infrared (PIR) motion detector.
The e529 interfaces with all common HVAC unit voltage configurations (24 volt
to 277 volt). The e529 can be installed in a wireless INNCOM guestroom
control system, which makes installation feasible and affordable in either new
construction or retrofit installations.
Through interfaces with other devices and sensors, the e529 supports the
following functions:
Remote HVAC control
• Guestroom HVAC diagnostics
• Remote room occupancy indication
• Automatic lighting control
• Remote mini-bar access reporting
• Remote smoke detector annunciation
• Central Electronic Lock control
• Humidity control
• Remote drape control
• Outside temperature display
• Peak demand load shedding
• Property/Building Management System (PMS/BMS) interface
