e528 Smart Digital Thermostat
Product Guide
Overview
INNCOM's e4 Smart Digital Thermostat is a po erful, multi-purpose Direct Digital Control (DDC) device that
can control virtually any HVAC system found in hotel guestrooms.
The three e4 models meet different application requirements. The e528 and e527 are
ired and are typically used for ne installation. The e529 is battery-po ered and is
designed to meet the needs of existing properties here re iring is not practicable.
This document describes Model e528; information on the e529 and e527 can be found
in their respective product guides.
Application
In its most basic form, the e528 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 gate ay.
For example, coupled ith a magnetic door s itch ( ired or ireless), 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 ith five relays and can be equipped ith an on-
board Infrared (IR) or radio frequency (RF) transceiver and Passive Infrared (PIR) motion detector.
The e528 interfaces ith all common HVAC unit voltage configurations (24 volt to 277 volt). The e528 can be
installed in a ired or ireless INNCOM guestroom control system, hich makes installation feasible and
affordable in either ne construction or retrofit installations.
Through interfaces ith other devices and sensors, the e528 supports the follo ing 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

A centrally controlled EMS package is created hen the e528 is connected to the property's Central Interface
Net ork (CINET) ith a pair of lo voltage ires or by the property’s high-speed TCP/IP net ork ith the
addition of a TCT (an Ethernet gate ay device). RF net orking is possible ith radio equipped models.
The e528 features a guest-friendly graphic interface ith intuitive controls (Figure 2). A user guide for the e528,
ritten primarily for installers and facility management personnel, is available (see References belo ).

Ho ever, 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 all, 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 a ay from direct sunlight or
radiant heat, air discharge grills, stair ells, outside doors, steam or ater pipes, arm air stacks,
unheated/uncooled areas, or sources of electrical or radio interference. The unit should not be placed on an outside
all or behind a door. It is essential that the e4 is mounted flush to the all and mounted level in both the horizontal
and vertical planes; incorrect mounting can degrade IR, PIR, and temperature measurement performance.
Installation Requirements or e4 equipped with PIR Motion Detection
The e4 thermostat can be equipped ith a PIR detector to augment the energy management scheme by detecting
motion in the guestroom. Consider the PIR’s vie angle, range characteristics, and mounting position to ensure
proper coverage. Figure 3 belo sho s the ranges of the flat and standard PIRs.

Mounting: The e528 is usually mounted on a standard double-gang (4 x 4) junction box. If mounted on a single-
gang box, the left side (display side) of the e528 overlaps the all area to the left of the junction box. A lo -
voltage mounting plate, mud ring, or lo -voltage caddy may be used for mounting 24 volt applications.
To mount the e528:
1) Remove the t o small scre s at the base of the e528.
2) Pull the bottom of the back-mounting plate slightly a ay from the front housing and then pull the back-
mounting plate do n.
3) Position the back plate insulator ithin the mounting plate as sho n in Figure 4.
4) Attach the mounting plate to the junction box, using the mounting scre s provided ith the e528. Ensure
that the plate is mounted ith the raised arro pointing UP.
To simplify installing and removing the e528, the headers and sockets described belo and sho n in Figure 5 are
located on the back of the e528. These accept pre-made iring harnesses provided by INNCOM. (Note: Take care
to note hich e528 model is being used. Each model has slightly changed headers and connectors as identified in
the dra ings belo .)

External temperature control sensor: This header accepts the iring harness from an external temperature probe
that can be used to supply the e528 ith remote temperature measurements. The e528 uses a 10K 1% thermistor
for external temperature measurement. This external temperature sensor can be used to monitor room
temperature at a different location from here the e528 is mounted or to monitor pipe ater temperature.
RS485 Networks: (refer to Figure 5)
E528.2G can be connected to the RS485 FLN5 net ork by installing the 02-9496 module, then connecting the
RS485 net ork to pins 5 and 6 of the lo voltage comm /device connector as described in Table 3 above.
E528.3G cannot act as the media gate ay for in-room traffic to ards the RS485 net ork. The most common
ay to connect the e528.3G is to connect a PC-485.S5 (P/N: 01-9905) on the S5bus.

Wiring: The steps belo provide an overvie of the iring process. Refer to the as-built iring diagrams
provided for exact details.
1. If applicable, use ire nuts to connect the 6-pin lo -voltage harness ires to the applicable lo -voltage
communication (if e528 is part of a ired RS485 centrally controlled system), door/ indo s itch, or
external PIR iring ithin the electrical box (Figure 8). Plug the 6-pin lo voltage harness onto the e528 lo
voltage comm. / device connection header.
2. Use ire nuts to connect the 10-pin Molex iring harness to the po er and valve/fan control signal ires
ithin the electrical box.
3. Plug the pre- ired 10-pin connector into the female receptacle at the back of the e528.
4. Hook the tabs at the top rear of the e528 housing into the matching depressions at the top of the mounting
plate and rotate the bottom of the housing to ard the all until it snaps into place on the mounting plate.
5. Secure the housing to the mounting plate ith the t o small scre s removed in Step 1 of the Mounting section.
6. Apply po er to the e528 by closing the applicable supply breaker. Verify that the e528 po ers up. Several
values should begin appearing on the LCD display.
7. Once installed and connected to po er, the e528 Digital Thermostat typically requires some configuration,
specifically:
•If installing the e528 as part of a net orked, centrally controlled EMS, a unique net ork address must be
assigned to the e528. This is done by entering Service Parameter mode on the e528 and changing the

E 5 2 8 P r o d u c t G u i d e P a g e 1 0 o f 1 8
values of Parameters 10, 11, and 12, hich hold the 5-digit net ork address of the e528. This 5-digit
number is typically the room number in most applications. A “Room List” document is typically
available that lists all rooms and the associated values to set into Parameters 10, 11, and 12. Refer to
Reference A, Section 5.1, for complete instructions for setting the e528 net ork address.
•If the particular HVAC equipment installed as not kno n hen the e528 as shipped, the fan and
heat/cool control outputs of the e528 must be configured to correctly operate the installed HVAC
equipment. Setting the appropriate HVAC control parameters of the e528 to the required values and
resetting the device reconfigures the e528 to properly control most HVAC units. Refer to Reference A,
Section 5.2, for instructions on changing the e528 HVAC related parameters, if required.
NOTE: If installing 01-9560 64K memory e528 Digital T ermostats, be aware t at t ese devices support t e
INNCOM ES-1 Flas Memory Module. T e ES-1 provides t e ability to copy HVAC related parameter settings
from a “golden” e528 t at as previously been installed in a room and ad its HVAC related parameters set
correctly and verified operationally wit t e HVAC equipment. Once t ese settings are copied to t e ES-1
module, plugging t e ES-1 into a new t ermostat automatically uploads t e settings.
