INTRODUCTION

New building construction and energy saving techniques have driven the need for improved communications between appliances and building environmental systems. There are several different protocols that have developed for accomplishing this task

including BACnet and Modbus. Since appliances come with a

variety of controls, interfacing with the various protocols presents different challenges.

Industrial Control Communications (ICC) has developed the devices to act as a communication gateway allowing appliances to communicate to the different building management protocols. The ICC module translates the appliance codes and commands into the appropriate protocol language giving the end user the ability to monitor and control the appliance. The end user will be able to adjust and monitor the equipment and obtain better levels

of efciency and cost savings.

The ICC module in this kit has been designed to seamlessly integrate with the water heater controls. Once the unit is connected to the control and to the energy management system,

the user will be able to operate the unit with the Building

Management system interface.

WARNINGS

When installing the unit, ensure that all power is off before opening any water heater enclosure. Failure to do so could result

in electrical shock and/or possible damage to the unit.

Do not install in areas of high temperature, in excess of 167° F. Install in areas not subject to water or excess moisture.

lists and instructions required to install and congure to your water heater/boiler and BMS system.

Before plugging in the ICC Gateway, install the ICC Conguration Studio from the USB key and run the program. Once running, select File, Open Project and browse to the USB key and select the conguration le whose name matches the gateway,

Because some USB hubs may not supply sufcient current to run

the Gateway, insure that the ICC Gateway is connected to the

power adaptor. Then connect the ICC Gateway using the USB

cable provided. Run the ICC Gateway Studio application from the start menu.

Each conguration has default address and BACnet instance

settings that can be changed. For Mirius gateways, the default

Modbus address is 1 and the default BACnet address is 81. For gas models the default BACnet Instance Number is 520081 and

for electric models the default instance number is 530081. For Ethernet Gateways, the default setting is to acquire an IP address automatically from the router (DHCP). If a static IP address is desired this can also be set. To change these addresses and

communication settings, use the ICC Conguration Studio

application program. The latest version of this application program can be downloaded from:

www.iccdesigns.com/icc-conguration-studio.html

Before making any changes, it is recommended to save the installed conguration project using the disk icon or File -> Save

Project As, then give it a name and select the folder, nally press Save.

To change the Instance number and the Device Name, scroll down and select the Device Object and replace the text in the boxes in the upper right corner.

TOOLS REQUIRED

Wire Cutters

24 AWG Wire Stripper

2.5 mm Flat Blade Screw Driver

GENERAL GUIDELINES

The module should be installed as close as practical to the water heater control.

The ICC module uses a 120 Volt power adapter to supply 9 volts DC for the unit. One 120 VAC outlet is required for each module installed. The power adapter comes with a six foot length of wire. If additional wire is needed, extra wire may be added, in accordance with local ordinances for installation of low voltage wire.

The ICC Gateway kit contains a USB key with the ICC Conguration Studio program, all conguration les, parameter

Figure 1. Changing Instance Number and Device Name

For ETH-1000 (Ethernet interface) the IP settings, including

DHCP/Static, the IP address and authentication can be changed

by selecting Ethernet from the upper left hand window and changing the text and drop down list selection similar to changing the Instance number above.

For Mirius (RS-485 A interface for BACnet MS/TP or ModBus

RTU), the baud rate and other serial communication parameters can be changed by scrolling down to and selecting RS-485 A -> ModBus RTU Slave.

Page 4

Figure 2. Changing ModBus Parameters

The ModBus address can be changed by selecting Node under the RS-485 A -> ModBus RTU item.

Likewise for BACnet, the baud rate and other serial

communication parameters can be changed by scrolling down to

and selecting RS-485 -> BACnet MS/TP Server. The BACnet

MAC Address can be changed by selecting Node under the

RS-485 A->BACnet MS/TP Server.

Warning: Do not change any other values other than these or the

gateway conguration may not function properly. In this case, the le saved above can be reloaded to start over.

INSTALLATION CONSIDERATIONS

There are two types of displays to consider when installing the ICC gateway modules to the water heaters, the older type with membrane switches and the newer style with a touch screen. The new touch screen style display does not need the provided RJ-485 splitter and it can be discarded.

TOUCH SCREEN STYLE DISPLAY INSTALLATION

HIGH EFFICIENCY WATER HEATER INSTALLATION – (BTH OR BTX MODELS)

Follow the directions under general guidelines for connecting the module to the Energy Management System and power. This section will guide the installer on how to mount and connect the module to the water heater. The control box and mounting location on the water heater is on the top of the unit behind the display module. See Figure 13.

Connection of the RJ-45 end of the communication cable to the heater is required to plug into J13 of the control board inside the

“black controls box” (for newer models) requiring removal of two

screws holding the lid on. After plugging in the communications cable, route the cable to the bottom side with the other cables and put the lid back on with the two screws.

If the control board is in a “grey controls box” (for older model),

double check to make sure the display is not one with membrane switches below and to the right of the display. If the display uses membrane switches, please follow directions under the section

“MEMBRANE SWITCH STYLE DISPLAY INSTALLATION”. If it

has a grey box and is a touch screen display (replacement of original) then the communications cable must be plug inside the box to J9 or J10. This will require removal of the two screws holding the lid on. After plugging in the communications cable, route the cable to the right side with the other cables and put the lid back on with the two screws.

Xi 1.0 Energy Management System (EMS) Control

Xi 1.0 uses a single bit setting method. Within the EMS Mode-Status point one bit command (bit 15) sets it in EMS mode, and other

ends EMS mode. Once in EMS mode, another bit command (bit 0) enables heating another disables heating.

Once in EMS mode the EMS Mode Refresh command must be periodically issued which clears a third bit (bit 14) to maintain EMS mode, otherwise the heater will end EMS mode and resume normal operation.

Page 21

BACnet / Gas Water Heaters

Table 12. Xi 1.0 Energy Management System (EMS) Control

Decimal Hex Value Response

0000 0x0000 EMS Disable heating^ 49152 / 0xC000

0001 0x0001 EMS Enable heating^ 49153 / 0xC001

3584 0x0E00 EMS Mode Refresh^ (must write within 30 seconds

or EMS mode ends.) 15 seconds or less recommended

Notes:

The start of a heating also depend on other factors like tank temperature dropping below Setpoint – Differential and External T’stat call for heat if that option is enabled.

Depending on when you poll the register, you may read bit 14 as 1 which is why a “C” (in hexadecimal form) might brieﬂy reply with “8”. This is due to the control setting this bit and if it not cleared periodically by the BACnet command, heating is disabled.

After disabling EMS mode with write of 3840, read back might have bits 14 and 1 possibly still set. To make sure these bits are clear, write a 0000 to clear bit 1 and 3584 to clear bit 14.

Mxi Energy Management System (EMS) Control

Mxi EMS control is written as a single command to place in EMS mode and enable or disable heating.

Once in EMS mode the EMS Mode Refresh command must be periodically issued to maintain EMS mode, otherwise the heater will end EMS mode and resume normal operation.

49152 / 0xC000 or 49153 / 0xC001 depending on

whether or not heating is enabled.

32768 0x8000 EMS Disable Heating^ 49152 / 0xC000

32769 0x8001 EMS Enable Heating^* 49153 / 0xC001

Notes:

~ For Versions less than 3.16, once EMS control mode is enabled it remains enabled through BACnet it will remain in EMS control mode that cannot be cleared by writing

a 0 to it. Power cycling only can clear EMS mode.

^ Depending on when you poll the register, you may read bit 14 as 1 which is why a “C” (in hexadecimal form) might brieﬂy reply with “8”. This is due to the control setting

this bit and if it not cleared periodically by the BACnet command, heating is disabled.

* EMS command to heat must be sent every 30 maximum or heating will be disabled.

Energy Management System (EMS) Control

Commercial Electric water heaters with Xi controls use a single bit setting method. Within the EMS Mode-Status point one bit

command (bit 15) sets it in EMS mode, and other ends EMS mode. Once in EMS mode, another bit command (bit 0) enables heating another disables heating.

Once in EMS mode the EMS Mode Refresh command must be periodically issued which clears a third bit (bit 14) to maintain EMS mode, otherwise the heater will end EMS mode and resume normal operation.

The start of a heating also depend on other factors like tank temperature dropping below Setpoint – Differential and External T’stat call

for heat if that option is enabled.

^Depending on when you poll the register, you may read bit 14 as 1 which is why a “C” (in hexadecimal form) might brieﬂy reply with “8”. This is due to the control setting this bit and if it not cleared periodically by the BACnet command, heating is disabled.

After disabling EMS mode with write of 3840, read back might have bits 14 and 1 possibly still set. To make sure these bits are clear, write a 0000 to clear bit 1 and 3584 to clear bit 14.

Xi 1.0 Energy Management System (EMS) Control

Xi 1.0 uses a single bit setting method. Within the EMS Mode-Status point one bit command (bit 15) sets it in EMS mode, and other

ends EMS mode. Once in EMS mode, another bit command (bit 0) enables heating another disables heating.

Once in EMS mode the EMS Mode Refresh command must be periodically issued which clears a third bit (bit 14) to maintain EMS mode, otherwise the heater will end EMS mode and resume normal operation.

recommended

Notes:

• The start of a heating also depend on other factors like tank temperature dropping below Setpoint – Differential and External T’stat call for heat if that option is enabled.

• Depending on when you poll the register, you may read bit 14 as 1 which is why a “C” (in hexadecimal form) might brieﬂy reply with “8”. This is due to the control setting

this bit and if it not cleared periodically by the BACnet command, heating is disabled.

• After disabling EMS mode with write of 3840, read back might have bits 14 and 1 possibly still set. To make sure these bits are clear, write a 0000 to clear bit 1 and 3584 to clear bit 14.

Mxi Energy Management System (EMS) Control

Mxi EMS control is written as a single command to place in EMS mode and enable or disable heating.

Once in EMS mode the EMS Mode Refresh command must be periodically issued to maintain EMS mode, otherwise the heater will end EMS mode and resume normal operation.

Table 41. Mxi Energy Management System (EMS) Control

Notes:

~ For Versions less than 3.16, once EMS control mode is enabled it remains enabled through BACnet it will remain in EMS control mode that cannot be cleared by writing

a 0 to it. Power cycling only can clear EMS mode.

^ Depending on when you poll the register, you may read bit 14 as 1 which is why a “C” (in hexadecimal form) might brieﬂy reply with “8”. This is due to the control setting

this bit and if it not cleared periodically by the BACnet command, heating is disabled.

* EMS command to heat must be sent every 30 maximum or heating will be disabled.

Energy Management System (EMS) Control

Commercial Electric water heaters with Xi controls use a single bit setting method. Within the EMS Mode-Status point, one bit

command (bit 15) sets it in EMS mode, and other ends EMS mode. Once in EMS mode, another bit command (bit 0) enables heating; another disables heating.

Once in EMS mode the EMS Mode Refresh command must be periodically issued which clears a third bit (bit 14) to maintain EMS mode, otherwise the heater will end EMS mode and resume normal operation.

Decimal Hex Value Response

3840 0x0F00 No EMS control 0 / 0x000

3841 0x0F01 Put into EMS Mode^ 49152 / 0xC000

0000 0x0000 EMS Disable heating^ 49152 / 0xC000

0001 0x0001 EMS Enable heating^ 49153 / 0xC001

3584 0x0E00 EMS Mode Refresh^ (must write within 30 seconds or

EMS mode ends.) 15 seconds or less recommended

NOTE:

49152 / 0xC000 or 49153 / 0xC001 depending

on whether or not heating is enabled.

The start of a heating cycle also depends on other factors, like Tank Temperature dropping below Setpoint – Differential and External T’stat Call for Heat if that option is enabled.

^Depending on when you poll the register, you may read bit 14 as 1, which is why a “C” (in hexadecimal form) might brieﬂy reply with “8”. This is due to the control setting this bit and if it not cleared periodically by the Modbus command, heating is disabled.

After disabling EMS mode with write of 3840, read-back might have bits 14 and 1 possibly still set. To make sure these bits are clear, write a 0000 to clear bit 1 and 3584 to clear bit 14.
