Description

The BMS Gateway accessory for e-Series and R513A C-Series heat pumps allows direct communication from a heat pump to building management systems programmed by third parties. It allows commands and data to be transferred in both directions.Older R134A C-Series heat pumps are compatible with this accessory; however, some points will not be available on older units. BMS-C gateways are recom-mended with R134A C-Series heat pumps The gateway is installed inside the heat pump’s elec-trical enclosure on a factory-supplied DIN rail. Then, it is wired to the BMS system through Ethernet and/or control wiring terminals. One gateway accessory package is required for each heat pump that is to be connected to a BMS system. Systems with Main Control Panels do not need this accessory if the BMS Gateway option was selected for the MCP, and the MCP installation manual should be consulted for configuration information for those systems.
Your gateway may be field-installed, or it may be factory-installed. If factory-installed, refer only to the “Field Supplied Items Required” and “Configuration and BMS Integration” sections of this manual.

  • Installation
  • Mounting
  • Note: If the gateway unit was factory-installed,please skip this section.
  • To mount the gateway:

DANGER

Power the heat pump off at the breaker so no live voltage power is present at the unit to prevent injury or death due to electrical shock.

  1. Open the door to the electrical enclosure.
  2. Identify the mounting location. The heat pump will have a vacant DIN rail space in the electrical enclo-sure box available to mount the gateway. The exact location of the vacant DIN rail space varies by heat pump or main control panel, and can be found in the installation manuals for those products in their “Control Wiring” sections. The gateway unit can be mounted vertically or horizontally
  3. Hook the Gateway unit over the top DIN rail in the specified mounting location.

Configuration and BMS Integration

WARNING: DO NOT connect the heat pump to the building network before gateway configuration! This will potentially overwrite the default IP address of the gateway and make finding the gateway on the network more difficult. If this occurs, it may be necessary to find the gateway on the network using the MAC address on the gateway label.

Configuration Prep and Login 

  1. Power up the heat pump, and allow it to finish its startup, before attempting to configure the BMS gateway. After startup is completed, connect a laptop or PC directly to the gateway, using the ethernet port on the gateway.
  2. Open a web browser and connect directly to https://192.168.1.24
  3. You may get a “Web Server Security Uncon-figured” message. It is ok to proceed with HTTPS from that warning message.
  4. You may get a “Your Connection is not Pri-vate” message. If so, click “Advanced”, and click “proceed to 192.168.1.24 (unsafe)”.
  5.  Login to the gateway web interface. Username is “admin”. Password is written on the gateway’s la-bel, and is also available via QR code on the gate-way. It may be necessary to temporarily unseat the gateway from the DIN rail to read the label.
  6. On the first login, the security mode will need to be set. Nyle recommends “Basic HTTP” or “HTTPS with own trusted certificate”.
  7. After selecting a mode, you will get a “redirecting” message, and then the Fieldserver GUI should open.

Network Settings

  1. To configure network settings, on the GUI land-ing page, click on the “Settings” tab. Within “Set-tings”, click on the “Network” tab.
  2. On the first connection, you will get a warning message that you are about to leave the reg-istration process. Click “Exit Registration”.
  3. You should now see a page with “ETH 1” and “Routing” tabs. Click the “Routing” tab.
  4. Select the default connection in the first row of the table.
  5. Click the “Add Rule Button” to add a new row.
  6. Set a new Destination Network, Netmask, and Gateway IP Address as needed.
  7. Set the priority for each connection from 1 (highest) to 255 (lowest).
  8. Click the “Save” button.
  9. Now click the “ETH 1” tab to access the ethernet settings.
  10. Be advised, if IP addresses are changed, you will need to reconnect to the gateway via your browser using the new IP address before you can continue with configuration settings! Only proceed once ready to connect to the building’s network.
  11. DHCP to automatically accept IP settings can be enabled here, or IP settings can be manually configured.
    1.  For manual configuration, set IP Address, Netmask, Default Gateway, and Domain Name Server.
    2.  If the gateway will be connected to a router, the gateway MUST set the “Gateway” field to the IP address of the router.

Testing
Good practice will include thorough verification that values reported by the heat pump match the values received in the BMS system. Ideally, this would include monitoring through an active heat demand and comparing BMS-reported values to heat pump-reported values. In addition, system communication can be checked. For serial connections, check that the TX and RX LEDs are rapidly ashing. You can also log into the field server GUI with a web browser, as in the “configuration” section. From there, clicking on “Diagnostics and Debugging” and then on “connections”, shows you a table of communication connections. The “errors” column would indicate if there are errors requiring additional troubleshooting. Communication errors are usually caused by:

  • Baud rate, parity, data bits, or stop bits set incorrectly
  • Device addresses incorrectly
  • Wiring problems
  • Device not listed in the Web Configurator
  • IP Addressing incorrect.

If communication errors cannot be troubleshot, a “Di-agnostic Capture” can be taken and emailed to Nyle Water Heating for assistance.

  1. Connect to the field server GUI with your web browser
  2. Click on “Diagnostics”
  3. Select “Full Diagnostic”
  4. Set the capture time period
  5. Click Start. When the capture period is finished, a download button will appear.
  6. Download the capture
  7. Email the capture to NWHScontrols@nyle.com, along with any supporting information needed to describe your problem.
