Figure 1. E528 Digital Thermostat

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 batterypowered 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:

• 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).

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 Box Back Mounting Plate Back Plate Insulator

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 i F

igure 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 rais 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.)

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.

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

3. Plug the pre-wired 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 toward the wall until it snaps into place on the mounting plate.

5. Secure the housing to the mounting plate with the two small screws removed in Step 1 of the Mounting section.

6. 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.

7. 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 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.

NOTE: If installing 01-9560 64K memory e528 Digital Thermostats, be aware that these devices support the INNCOM ES-1 Flash Memory Module. The ES1 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.
