Applications
The Johnson Controls® VRF Smart Gateway enables
the integration of the Hitachi VRF system with a building
automation system (BAS), such as the Metasys® system.
The VRF Smart Gateway performs this function by
communicating between the native H-Link
communications network of the Hitachi VRF system and
the open building standard BACnet®/IP network. The
VRF Smart Gateway intelligently provides the VRF device
and point data over the BACnet/IP network in a way that
the BAS can easily discover. The VRF Smart Gateway
therefore requires little or no post-integration configuration
within the BAS. The VRF Smart Gateway includes a
simple web server that provides a wireless mobile user
interface for configuring communication parameters and
performing VRF system discovery and device naming.
The wireless connection on the VRF Smart Gateway
allows users of a supported mobile device to be up to 30
m (100 ft, line of sight) away. Power must be supplied
using the provided external power supply.

Special Tools Needed
The unit supports both DIN rail and surface mounting
options. If the unit is permanently mounted to a vertical
surface without a DIN rail, you need screws to mount the
unit. The specific screw types depend upon the surface
to which the unit is mounted. The screw holes on the VRF
Smart Gateway can accommodate M3.5 and #6 screws.
To configure the VRF Smart Gateway using the gateway's
Wi-Fi access point, you need a mobile device (tablet or
smartphone) or computer (laptop or desktop) that
supports Wi-Fi.
Location Considerations
Observe the following guidelines when mounting a VRF
Smart Gateway:
•Mount the VRF Smart Gateway in areas free of
corrosive vapors and observe the environmental
limitations listed in the Technical Specifications
section of this document.
•Objects (including ductwork, cabinets, doors, and
glass) can impede the wireless signal. Minimize the
number of objects between the connected computer
or mobile device and the VRF Smart Gateway. Use
line of sight, if possible.
•Metal objects (such as cabinet doors, enclosures, and
pipes) and concrete objects (such as pillars, walls,
and ceilings) may limit Wi-Fi service. To
accommodate potential structural obstacles on site,
the VRF Smart Gateway can be mounted flush
against the wall or perpendicular to it.
•The VRF Smart Gateway is not rated for outdoor
mounting.
Mounting Locations
The VRF Smart Gateway can be attached to a 1-1/8 in.
(35 mm) DIN rail or a flat, vertical surface. Mounting the
unit on a ceiling or in a way that positions the front of the
unit facing down is not recommended.
Although the unit has two mounting clips, only the bottom
clip snaps inward. The top clip is permanently locked in
the outward position, and it can be used as an additional
hole for screwing the unit into place. If not utilized for DIN
rail or surface mounting, the top and bottom clips may
be removed from the unit.
DIN Rail Mounting
To mount the unit on a DIN rail:
Mounting
We recommend mounting the unit either vertically (upright
and flush) or horizontally (sideways and flush). This
flexibility allows the unit to be mounted in a way that
minimizes spacial constraints and maximizes placement
options for optimal wireless signal strength.
The unit should be mounted in such a way that labels
can be read if they are visible. (For example, do not mount
the unit upside down, which puts the labels upside down.)
1. Securely mount a 3 in. (7.5 cm) or longer section of
1-1/8 in. (35 mm) DIN rail in the required space.
2. On the unit, pull the bottom mounting clip outward to
the extended position.
2VRF Smart Gateway Installation Instructions

Figure 1: Positioning the Unit on a DIN Rail
Figure 2: Sample Permanent Mounting, Back-side
Screws
3. Hang the unit on the DIN rail by the hooks at the top
of the DIN rail channel (on the back of the bracket),
and position the unit snugly against the DIN rail.
4. Push the bottom-mounting clip inward to secure the
unit on the DIN rail.
Wall Mounting
The unit may be mounted using the holes in the DIN rail
clips. This orientation helps accommodate on-site
constraints. Screw hole locations are illustrated in Figure
3.
The screw types needed to mount the unit depend upon
the surface to which the unit is mounted. The screw holes
on the VRF Smart Gateway can accommodate M3.5 and
#6 screws.
For information on location considerations for maximizing
signal strength, see the Mounting section.
To mount the unit on a flat surface (such as a wall):
1. Pull the bottom mounting clip outward to the extended
position.
2. Mark mounting hole locations on the wall using the
dimensions shown in the following figure; or hold the
bracket against the wall and mark the hole locations
through the mounting clips.
Note: The position of the location holes depends on
whether the bracket is mounted horizontally
or vertically.

Wiring the H-Link Network
To wire the H-Link Network of the VRF Smart Gateway:
•Connect the two H-Link cable wires to the left
terminals indicated in the following figure.
•If the VRF Smart Gateway is connected at an
intermediate position of the H-Link network as
opposed to the end of the network segment, use the
right terminals shown in the following figure to
continue the H-Link network.
Figure 4: H-Link Cable Insert Position
Note: The screw holes on the VRF Smart Gateway
can accommodate M3.5 and #6 screws.
3. Drill holes in the wall based on the locations marked
in the preceding step, and insert wall anchors for each
hole (if necessary).
4. Hold the unit in place, insert the screws through the
mounting clips and into the screw holes, and then
carefully tighten all screws.
Important: Do not overtighten the mounting screws.
Overtightening the screws may damage
the mounting clips or bracket.

starts to discover the VRF system and devices. View the
Device List from the VRF Smart Gateway UI to see the
discovered VRF devices.
Reset Button Operation and
Descriptions
If you lose your password or if you want to restore the
unit to factory defaults, the VRF Smart Gateway offers
two reset functions: a Network Reset function that resets
Wi-Fi and Ethernet settings, and a Reset to FactoryDefaults function that resets all unit settings (including
user-configured VRF equipment names and descriptions).
Reset to Factory Defaults also resets your SSL certificate
to the Johnson Controls self-signed certificate that is in
the device when it comes from the factory.
For information on resetting the unit, see Table 1.
Important: To use a unit that is reset to factory defaults,
you must have the default login information
supplied in the Quick Start Guide that
shipped with the unit. The Reset to Factory
Defaults function does not change the
version of the application. If you did a
software upgrade, the VRF Smart Gateway
remains at the upgraded version rather than
resetting to the version that it was running
when it left the factory.
The reset button is on the side of the device, and it is
embedded into the VRF Smart Gateway housing so that
it cannot be activated by accident. To reach the reset
button, use a paper clip, pin, or similar tool.
Notes:
•If you are connected to the network, using the reset
button disconnects you.
•If you press the reset button for more than 9 seconds,
the reset operation is cancelled.
•If a fault condition already exists, the reset button is
disabled.
A software update may be available for your device. Visit
VRFPro.com or contact your nearest Johnson Controls
representative for the latest version. Refer to the VRFSmart Gateway User's Guide (LIT-12012385) for

Troubleshooting
Table 3: Launch Issues Troubleshooting Information
ResolutionProblem
You are not directed to the VRF
Smart Gateway login page when
you launch a web browser.
Every time I install the SSL
certificate on my device, it asks me
to re-install it. What should I do?
When I install the SSL key or
certificate, I receive the message
Error Saving SSL Settings.
Reason
Device behavior can vary based on the device and Internet browser in use. For instance,
some devices cache browser information and do not automatically redirect users to the
VRF Smart Gateway login page when the browser is launched.
Resolution
Make sure that your device is connected to the VRF Smart Gateway's Wi-Fi network.
Direct your browser to www.myvrfsg.com.
If the login page is taking too long to load, try using the Ethernet connection instead.
Resolution
Check your web browser settings and verify that cookies are enabled.
When an SSL key or certificate is corrupted, the SSL page detects it and alerts you to the
corrupted key or certificate.
However, if the corruption is minor, for example, an extra space was copied while installing
the certificate or a character was missed, the UI does not detect the problem and allows
the corrupted key or certificate to be saved. The server detects the error and returns the
Error Saving SSL Settings message. While this correctly prevents the bad key or
certificate from being used, it does not inform you as to the source of the problem.
In this case, reinstall the SSL key or certificate as described in the VRF Smart GatewayNetwork and IT Guidance Technical Bulletin (LIT-12012341).
Refer to the VRF Smart Gateway User's Guide (LIT-12012385) for information on Ethernet settings and SSL settings.
