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

E528 Product Guide Page 2 of 18 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).

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.

E528 Product Guide Page 4 of 18 Mounting: The e528 is usually mounted on a standard double-gang (4 x 4) junction box. If mounted on a singlegang box, the left side (display side) of the e528 overlaps the wall area to the left of the junction box. A lowvoltage 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.

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.
