INNCOM e528 Thermostat Installation Guide

Overview

INNCOM’s e528.4G* (the e528) thermostats utilize a CC2520 2.4 Ghz IEEE 802.15.4 RF transceiver in their role as part of the Integrated Room Automation System (IRAS). The integration of the radio on-board the PCBA, along with other component changes, makes for a simpler, more efficient, and more cost-effective device. (Note that the legacy e528 and e528.4G are very similar in look and feel. If in doubt, check the bottom of the unit—the

4G has a photosensor located there.)

Features

The e528 thermostat provides

• Accurate temperature measurement +/- 1 degree F

• Multiple load actuating options from 24VAC–277VAC

• Motion sensor for occupancy detection

• RF transceiver for wireless 2.4Ghz guestroom and backhaul

network communications

• IR transceiver for guestroom network communications

• RS485 for wired backhaul network communications

• External temperature sensor support

Installation

CAUTION!

Disconnect the power supply before beginning installation to prevent electrical shock or equipment damage. All wiring must comply with local codes and ordinances.

1. Read instructions carefully. Failure to follow them could

damage the product or create a hazard.

2. Check the ratings given in the instructions and on the product

to make sure the product is suitable for your application.

3. Installer must be a trained, experienced service technician.

4. After installation is complete, check product operation as

indicated in instructions.

5. For variations of these systems, refer to the installation

instructions of the controlled equipment.

• Unheated (un-cooled) areas behind the thermostat

• If RF equipped, do not install near other RF

sources/transmitters When the thermostat is equipped with PIR, consider view angle, range characteristics, and mounting position for proper coverage.

Mounting

INNCOM’s DDC thermostats typically mount 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.

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, then pull the back-mounting plate down.

3. Position the back plate insulator within the mounting plate

as shown in Figure 3 below.

4. Feed wires through the insulator to minimize airflow.

5. Attach the mounting plate to the junction box using the

mounting screws provided. Ensure that the plate is mounted with the raised arrow pointing UP.

Wiring

Location

Select a location about 1.5m (5ft.) above the floor with good air circulation at average temperature. Do not mount thermostat where it may be affected by

• Drafts or dead spots behind doors or in corners

• Hot or cold air from ducts

• Radiant heat from sun or appliances

• Concealed pipes or chimneys

“2G,” “3G,” and “4G” are internal INNCOM product desig n ations used for convenience to diff e rentiate individual hard w are configurations. No difference in device capability or effectiveness is implied. Due to end-of-life for certain 2G and 3G components, the e528.4G is now the standard INNCOM install, but 2G and 3G installations are still supported.

E528.4G Retrofit Installation

The e528.4G can be used to retrofit an application where a legacy e528 was used. Follow the procedure below:

4G to 2G Standalone application: with/without door switch input (no backhaul network)

E528 New Installation

Stand alone application with/without door switch input

• Using the harness (P/N 62-1467), make the appropriate wire

connections, then plug the harness into H7 of the e528. Refer to low-voltage connections diagram.

RS485 Networked Application with/without door switch input

• Using the harness (P/N 62-

1467), make the appropriate wire connections, then plug the harness into H7 of the e528. Refer to low-voltage connections diagram.

• Using the adapter (P/N 203-

250) and P/N 62-1532-B.12 cables, connect the RS485 incoming pair to two pin header H1 and the out-going pair going to the next thermostat to header H3.

• Connect the harness of 203-

250 to H5 of the e528.

E528 RF Installation

• Typically only a wired door switch contact would be

required for this application (can also use wireless door switch contact) or possibly a remote temperature sensor. In this case, using the harness (P/N 62-1467), refer to lowvoltage communications connections table.

• Connect harness (P/N 62-1467) to H5 of e528.

Power and Actuator Connections

Refer to line voltage connections table

• Use wire nuts to connect the 10-pin Molex wiring harness to

the power and valve/fan control signal wires within the electrical box. See pre defined commissioning document which describes the specific wire connections for the application

• Plug the pre-wired 10-pin connector into the female

receptacle at the back of the e528. Note: this will connect the unit to the input power and relays to the loads.

Note: When using mixed voltage, voltage separation must be maintained. Line voltage must reside in the right side of the gang box. Low voltage must reside in the left side of the gang box.

• 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. Values should begin appearing on the LCD display.

• Press OFF/AUTO. Default Room ID 65535 will scroll

• Set highest digit (0–6) using the UP/DOWN arrows. Press

DISPLAY

• Set middle 2 digits (0–99). Press DISPLAY

• Set lowest 2 digits (0-99). Press DISPLAY. The new number

will scroll across LCD. The e528 will return to the menu list

Commissioning

The e528 digital thermostat requires configuration to work effectively. The most basic configuration is “binding” the room to the Room ID (usually the room number) to avoid cross communication between devices. (For commissioning of complex systems, please refer to the property specific commissioning document). Room IDs are 5 digit numbers (X YY ZZ, with zeros as placeholders where needed) ranging from 1 to 65535. To set Room ID

• Enter Service Mode:

• Press and hold °F/°C

• Press and release OFF/AUTO

• Press and release DISPLAY

• Release °F/°C

• Go to rid (Room ID)
