SAFETY CONSIDERATIONS
Read and follow manufacturer instructions carefully. Follow all
local electrical codes during installation. All wiring must
conform to local and national electrical codes. Improper wiring
or installation may damage thermostat.
Understand the signal words — DANGER, WARNING, and
CAUTION. DANGER identifies the most serious hazards,
which will result in severe personal injury or death.
WARNING signifies hazards that could result in personal
injury or death. CAUTION is used to identify unsafe practices,
which would result in minor personal injury or product and
property damage.
Recognize safety information. This is the safety-alert symbol
( ). When this symbol is displayed on the unit and in
instructions or manuals, be alert to the potential for personal
injury. Installing, starting up, and servicing equipment can be
hazardous due to system pressure, electrical components, and
equipment location.
Note that changes or modifications of this product are not
expressly approved by the party responsible for compliance
and could void the user’s authority to operate the equipment.
NOTE: This equipment has been tested and found to comply
with the limits for a Class B digital device, pursuant to Part 15
of the FCC rules. these limits are designed to provide
reasonable protection against harmful interference in a
residential installation. This equipment generates, uses, and can
radiate radio frequency energy and, if not installed and used in
accordance with the instructions, may cause harmful
interference to radio communications. However, there is no
guarantee that interference will not occur in a particular
installation.
If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the
equipment off and on, the user is encouraged to try to correct
the interference by one or more of the following measures:
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and the
receiver.
Connect the equipment into an outlet on a circuit different from
that to which the receiver is connected.
Consult dealer or an experienced radio/TV technician for help.
GENERAL
The DLS VRF Interface is a communication device that allows
you to connect ductless indoor units into VRF touch screen
central controller. Ductless indoor units, any style, will be
shown as high wall unit icon on the touch screen central
controller. Ductless indoor unit can be controlled using VRF
wired controller.

SELECTING INSTALLATION POSITION
Read this manual carefully before installing the interface
and keep the manual for future reference. The DLS VRF
Interface should be installed as close as possible to the
ductless indoor unit. Avoid installing DLS VRF Interface
near high voltage components and heat generating devices.
Follow the local code for wiring methods between DLS
unit, VRF touch screen central controller, and DLS VRF
Interface. Make sure the cover of DLS VRF Interface is
installed after wiring to avoid any moisture or dust
accumulation.
Do not install the controller in a place exposed to water or in
a condensing environment.
Do not install the device in a location where there is direct
sunlight or where the temperature may become greater than
118°F(48°C) or less than -4°F(-20°C).
This product is neither waterproof nor dust proof, so it can
only be installed indoors.
NOTE: The communication wire should be 2-core stranded
shielded 18 AWG cable.

DIP SWITCH SETTINGS
• ENC1/ENC2 are rotary dial whereas SW7 is ON/OFF.
• ENC2 is used to set the network address.
• Combination of ENC1 and SW7 allows you to set the
indoor unit address. See Table 4.
Example:
A system has 10 VRF indoor units and 2 DLS indoor units
with DLS VRF Interfaces. There is no automatic addressing
function for the DLS VRF Interface. If the VRF indoor units
are addressed 0-9, the DLS indoor units will be 10 and 11
following the settings in Table 4.

COMMON QUESTIONS
Q. How is the ductless indoor unit displayed on the touch
screen central controller?
A. The ductless unit will always appear as a high wall.
The icon cannot be changed to match the indoor unit
style (for example – cassette will appear as high wall).
However, you can change the name (for example
HWALL to CCAS).
Q. Is the DLS indoor unit controlled by the VRF or DLS
wall controller?
A. DLS indoor unit is controlled by the VRF wall
controller connected to HA/HB of the interface.
Q. What are the functions you can control through the
touch screen central controller for the DLS indoor unit?
A. The functions controlled through touch screen central
controller for the DLS indoor unit are:
• Set mode
• Set temperature
• Set airflow
• ON/OFF
• Set indoor unit address
• Set auxiliary heater
• Error codes
Q. What are the functions you can control through the
VRF wall controller for the DLS indoor unit?
A. The functions you can control through the VRF wall
controller for the DLS indoor unit are:
• Set mode
• Set temperature
• Set airflow
• ON/OFF
• Set indoor unit address
• Set auxiliary heater
• Error codes
Q. If there is a multi-zone system with (3) indoor units
serving (3) different zones / rooms, do I need (3)
separate DLS VRF Interface?
A. Yes, you need (3) separate DLS VRF Interfaces for each
DLS indoor unit.
Q. If there is a multi-zone system with (3) indoor units
serving the same zones / rooms, can I implement group
control option?
A. No, group control is NOT an option. All the DLS indoor
units will need separate DLS VRF Interfaces.
Q. Instead of the touch screen central controller, can I tie
the DLS VRF Interface to the BACnet Interface?
A. No, the DLS VRF Interface will not work with the
BACnet Interface.
Q. How many DLS VRF Interfaces I can connect to the
touch screen central controller?
A. You can connect up to a total of (48) DLS VRF
Interfaces to touch screen central controller, (8) DLS
VRF Interface per communication channel.
Q. Does the DLS VRF Interface need network address?
A. Yes, each DLS VRF Interface would need network
address. The address should be between 0 to 7 and
unique. Similar to addressing ODU / system on the
VRF side.
Q. Does the DLS indoor unit need a unique ID?
A. Yes, each DLS indoor unit will need a unique ID. The
address on the wall controller as well as the touch
screen controller should match; otherwise an error will
be displayed on the controller.
Q. Is a network resistor needed when the DLS VRF
Interface is used?
A. Yes, the 120 Ohm network resistor should be connected
to the XYE bus of the last DLS VRF Interface in the
system. If there are VRF heat pump units in the system,
connect one network resistor to the PQE bus of the last
indoor unit as normal and another resistor to the XYE
bus of the last DLS VRF interface.
