e528 Smart Digital Thermostat

Product Guide

Overview

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

P a g e 2 o f 1 8

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).

Ranges are determined by performing an RF link quality test using two identical e528 thermostats containing
radios as defined in tables 2 and 3. The maximum distance threshold is based on a 95% overall link quality.
Outdoor ranges were conducted in a low noise, free air environment. Indoor ranges are for reference. Indoor
ranges are impacted by the ambient environmental noise floor, and building construction materials.

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.

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:

Remove the two small screws at the base of the e528.

Pull the bottom of the back-mounting plate slightly away from the front housing and then pull the back-
mounting plate down.

Position the back plate insulator within the mounting plate as shown in Figure 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 below.)

Headers

The headers for the e528.2G, 3G and 4G

thermostats are substantially the same, though the layouts and labeling on

the PCB are slightly different (see Figure 5 above). The statements and tables 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 the
pinout for the 2G low voltage comm / device connector and lists typical functions for each pin. Table 3a shows

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)

E528.2G

can be connected to the RS485 FLN5 network by installing the 02-9496 module, then connecting the

RS485 network to pins 5 and 6 of the low voltage comm /device connector as described in Table 3 above.

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.

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.

Wiring:

The steps below provide an overview of the wiring process. Refer to the as-built wiring diagrams

provided for exact details.

If applicable, use wire nuts to connect the 6-pin low-voltage harness wires to the applicable low-voltage
communication (if e528 is part of a wired RS485 centrally controlled system), door/window switch, or
external PIR wiring within the electrical box (Figure 8). Plug the 6-pin low voltage harness onto the e528 low
voltage comm. / device connection header.

Use wire nuts to connect the 10-pin Molex wiring harness to the power and valve/fan control signal wires
within the electrical box.

Plug the pre-wired 10-pin connector into the female receptacle at the back of the e528.

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 toward the wall until it snaps into place on the mounting plate.

Secure the housing to the mounting plate with the two small screws removed in Step 1 of the

Mounting

section.

Apply power to the e528 by closing the applicable supply breaker. Verify that the e528 powers up. Several
values should begin appearing on the LCD display.

Once installed and connected to power, the e528 Digital Thermostat typically requires some configuration,
specifically:

•

If installing the e528 as part of a networked, centrally controlled EMS, a unique network 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, which hold the 5-digit network 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 network address.

•

If the particular HVAC equipment installed was not known when the e528 was 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  Thermostats,  be  aware  that  these  devices  support  the
INNCOM  ES-1  Flash  Memory  Module.  The  ES-1  provides  the  ability  to  copy  HVAC  related  parameter  settings
from  a  “golden”  e528  that  has  previously  been  installed  in  a  room  and  had  its  HVAC  related  parameters  set
correctly  and  verified  operationally  with  the  HVAC  equipment.  Once  these  settings  are  copied  to  the  ES-1
module, plugging the ES-1 into a new thermostat automatically uploads the settings.
