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.

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.
