Overview and
General Concepts
INNCOM's e4 Smart Digital Thermostat is a powerful, 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 wired and are typically used for new installation. The e529 is battery-
powered and is designed to meet the needs of existing properties where
rewiring 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 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 an on-board Infrared (IR) or
radio frequency (RF) transceiver and Passive Infrared (PIR) motion detector.
The e528 interfaces with all common HVAC unit voltage configurations (24 volt
to 277 volt). The e528 can be installed in a wired or 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 e528 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
A centrally controlled EMS package is created when the e528 is connected to
the property's Central Interface Network (CINET) with a pair of low voltage
wires or by the property’s high-speed TCP/IP network with the addition of a
TCT (an Ethernet gateway device). RF networking is possible with radio
equipped models.
The e528 features a guest-friendly graphic interface with intuitive controls
(Figure 2). A user guide for the e528, written primarily for installers and facility
management personnel, is available (see References below).

Table 1 e528 RF Characteristics
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.

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 wall area to the left of the junction box. A low-voltage mounting plate, mud
ring, or low-voltage caddy may be used for mounting 24 volt applications.
To mount the e528:
1. Remove the two small screws at the base of the e528.
2. Pull the bottom of the back-mounting plate slightly away from the front
housing and then pull the back-mounting plate down.
3. Position the back plate insulator within the mounting plate as shown in
Figure 4.
4. Attach the mounting plate to the junction box, using the mounting screws
provided with the e528. Ensure that the plate is mounted with the raised
arrow pointing UP.
To simplify installing and removing the e528, the headers and sockets
described below and shown in Figure 5 are located on the back of the
e528. These accept pre-made wiring harnesses provided by INNCOM.
(Note: Take care to note which e528 model is being used. Each model
has slightly changed headers and connectors as identified in the
drawings on the next page.)

The I/O headers for the e528.3G* and 4G* thermostats are substantially
different (see Figure 5 above). The statements and table below detail only the
headers that differ in function.
Low Voltage comm / device connector: This header accepts the provided 6-
pin harness used to connect low voltage communication, door/window position
switch, and other room devices to the e528. Table 3 shows pinout and function
for the 3G and 4G. For specifics, refer to the as-built wiring diagrams.
* “3G,” and “4G” are internal INNCOM product designations used for convenience to differentiate
individual hardware configurations. No difference in device capability or effectiveness is implied.
Due to end-of-life for certain 3G components, the e528.4G is now the standard INNCOM install,
but 3G installations are still supported.

External temperature control sensor: This header accepts the wiring
harness from an external temperature probe that can be used to supply the
e528 with 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
where the e528 is mounted or to monitor pipe water temperature.
RS485 Networks: (refer to Figure 5)
E528.3G cannot act as the media gateway for in-room traffic towards the
RS485 network. The most common way to connect the e528.3G is to connect
a PC-485.S5 (P/N: 01-9905) on the S5bus.
E528.4G to 2G RS485 Networked Application: with or without door switch
input (See Figure 6)
•Using the adapter (P/N 203-251), connect the harness from the wall
box (P/N 62-1462) previously connected to the thermostat being
replaced to H1 of the adapter.
•Connect the harness H3 (rainbow) of 203-251 to the low voltage
comm/device connection of the e528.4G
•Connect the harness H2 (black) of 203-251 to the RS485 header of the
e528.4G
NOTE: Take care to not reverse the connections to the e528.4G!

4G to 2G Standalone application: with/without door switch input (no backhaul network)
•Using the adapter (P/N 203-013) connect the harness from
the wall box (P/N 62-1462) previously connected to the
thermostat being replaced to H1 of the adapter
(see Figure 8).
•Connect the harness of 203-013 to the low voltage
comm/device connection of the e528.4G.
Molex 10-position female socket: This female socket
accepts the provided 10-pin Molex connector pre-wired with 8-
inch, color-coded wiring leads. These leads should be
connected to the 24VAC or 100–277VAC power, valve/fan
control wiring from the FCU, or other HVAC device with wire
nuts inside in the wall junction box in accordance with the
wiring diagram provided by INNCOM.
Note: For installations in which all leads are not required,
the extraneous leads should be cut off at the Molex
connector.
Figure 8 shows the pinout for the 10-position Molex male connector supplied with all relay output models
of the thermostat. The end view of the male connector from the wire insertion side with the pin numbers is
indicated. This is the same as looking at the female connector point on the back of the e528.
Typical functions for each wire are listed in Tables 4 and 5. For specifics, refer to the as-built wiring
diagrams.
