Important Safety Precautions

mproper handling can cause serious damage or injury. Please read the following safety information in its entirety.

Electrical Safety

• The product must be properly grounded at the time of installation, or electrical shock may occur.

• For all electrical work, follow all local and national wiring standards and regulations. Connect cables tightly, and clamp them securely to prevent external forces from damaging wiring terminals. Improper electrical connections can overheat and cause fire, and may also cause shock.

• All electrical connections must be made according to the Electrical Connection Diagram located on the unit’s control box and the panels of the indoor and outdoor units.

• All wiring must be properly arranged to ensure that the control board cover can close properly. If the control board cover is not closed properly, it can lead to corrosion and cause the connection points on the terminal to heat up, catch fire, or cause electrical shock.

• All wires must be properly sized according to the NEC/NFPA 70, CEC and all prevailing codes, ordinances
  and standards.

• Installation should be performed by a licensed contractor or electrician. Improper installation may result in electric shock or fire.

• Ensure the power to both the indoor and outdoor unit is diconected before installing this kit.

• Do not install the control box in area subject to excessive moisture, near flamimable liquids or gases.

Installation Safety

• Installation must be performed by an authorized dealer or specialist. Improper installation can cause water leakage, electrical shock, or fire. (In North America, installation must be performed in accordance with NEC and CEC requirements by authorized personnel only.)
• Installation must be performed according to the installation instructions. Improper installation can cause water leakage, electrical shock, or fire.
• The unit shall be installed in accordance with national and local wiring regulations. Contact an authorized service technician for repair or maintenance of this unit.
• Only use the included accessories, parts, and specified parts for installation. Using nonstandard parts can cause water leakage, electrical shock, fire, and can cause the unit to fail.
• Do not install the unit in area subject to excessive moisture.
• Do not install the unit near flammable liquids or gases, or fire may result.
• Do not install the unit in a location that may be exposed to combustible gas leaks. If combustible gas accumulates around the unit, it may cause a fire.
• Do not turn on the power until all work has been completed.
• If moving or relocating the unit, consult experienced service technicians for disconnection and reinstallation of the unit.

Installation Requirements

• The unit should be installed indoors. If installed outdoors, the thermostat MUST BE contained within an approved waterproof enclosure.
• Install the unit with 6″ of clearance around it and where it can be easily accessed for service.
• Install the unit in an area free from drips and moisture.

Unit Installation

Remove the cover.

1. Using a Phillips screwdriver, remove the eight (8) screws holding the cover in place and take off the cover.
   Mount the unit.

2. Mount the unit to a wall l (or raised floor surface) using the three (3) screws (M4x20) and three (3) anchors.
   Wire the unit.

   Secure the unit.

4. Replace the cover and secure it, using the screws removed in the first step.

Wiring and Configuring

Wiring the third-party thermostat interface
Follow the wiring diagram below to connect this thermostat interface kit between a third-party thermostat and a Durastar system.

Wiring Connection Specifications

1. When using the interface with a ducted indoor unit (DRAD##F1A), the static pressure must be set up by temporarily connecting the communication wires L1(1), L2(2), and S(3) and G from the outdoor unit to the indoor unit (see the DRAD install manual or service.durastar.com). Once the static pressure setup is complete, disconnect the units from each other and proceed to step two (2). If any other IDU is used proceed directly to step two (2).
2. Connect L1(1), L2(2), and S(3) from the outdoor unit to terminals 1, 2 and 3 on the right half of the power distribution block on the interface. Connect G to a ground block (green) terminal.
3. Connect L1(1), L2(2), and S(3) from the indoor unit to terminals 1, 2 and 3 on the left half of the power distribution block on the interface. . Connect G to a ground block (green) terminal.
4. Connect R and C from the 3rd party thermostat to board terminals R and C at CN15. Connect Y, W and G to wiring block terminals Y, W and G at CN19.
5. Follow the instructions in the Configuring the DIP Switches section to set the DIP switches in the 24V control box.
6. The thermostat must be configured for operation with a conventional system (in single stage cooling and heating). Do not configure the thermostat for heat pump operation.

WARNING

• All wires must meet National Electric Code ( NEC ) as well as local codes for proper sizes. Use the Electrical Data Table minimum circuit amps ( MCA ) and maximum over current protection ( MOCP ) to determine the proper wire sizes and fuse or breakers for the installation.

NOTE

• Only use 14/4 AWG stranded and shielded wire.
• Thermostat G to interface G is default.
• Verify power supply.
• The remote control can only be used to set the Swing and LED functions on appropriate indoor models after the thermostat interface is installed.
