Please refer to the product manual for more detailed information on system configuration, application scenarios, and connection wiring specifications.

Read this manual carefully before installing or operating your new air conditioning unit. Make sure to save this manual for future reference.

WARNING

• Wires must be properly sized according to the NEC/NFPA 70, CEC and all prevailing codes, ordinances and standards.
• All conductors must be installed with a strain relief eliminating stress on the wire following installation which may result in wire damage and/or overheating with a potential for fire. Installation must be performed in accordance with the  requirement of NEC and CEC by authorized personnel only.
• All wiring to be rated for the control box amperage rating.
• All wiring installed to meet general industry standards and practices,
• Do not install adapter near flammable liquids or gases.
• Do not operate the unit with wet hands, as this could lead to electrical shock.

CAUTION

• When connecting with RS 485 communication to the outdoor unit, shielded wire must be used and grounded at one end only.
• When using shielded wire the cable should be grounded at one end to reduce EMI.
• T1 sensor cable shall not exceed 23′ (7 m).

   2| Wiring tube (insulating sleeve and tightening screw)| 1

3. Select installation location
   DO NOT install the 24V INTERFACE KIT near flammable liquids or gases such as gasoline or hydrogen sulfide. Doing so creates a fire hazard.

Installation Method

1. Remove the cover of 24V INTERFACE KIT Remove the four screws of 24V INTERFACE KIT with a screwdriver or similar tool. Along the hem rotating separation lifted the lid.Minimum free space required around the kit is 7″ (180 mm).

2. Mount the back plate of the 24V INTERFACE KITMount 24V INTERFACE KIT vertically, and folding in on, fasten the back plate to the wall with 3 screws (M4x20) and anchors.
   NOTE:
   Place the unit on a flat surface. Be careful not to distort the back plate of the 24V INTERFACE KIT by over tightening the screws.

   • When installed vertically, the direction of the arrow must be up.

3. Wiring.

4. Cover the 24V INTERFACE KIT lid, locking screw.

System Configuration
NOTE:
Thermostat should be configured for use with a conventional system.
The remote controller, wiring controller, central controller and WIFI can not be used with this control box at the same time. Only the Swing and LED furcation can be used.

SYSTEM CONFIGURATION SCENARIOS
Four application scenarios°

Scenario No. 1:
Current loop (L1/L2/S or 1/2/3) communication inverter outdoor unit match with other conventional brand 24V indoor unit；

Match with following outdoor units ：

• Wall Mounted (Sizes 9K~36K) Cassette (Sizes 9K~24K)
• Ducted (Sizes 9K~24K)
• Console (Sizes 9K~12K)
• Floor ceiling (Sizes 18K-24K)

NOTE:

• T1(Room temperature) sensor should be located in the air inlet side.
• Must remove the TXV or other metering device from the indoor unit.

NOTE:

• T1(Room temperature) sensor should be located in the air inlet side.
• Must remove the TXV or other metering device from the indoor unit.
• If the indoor unit already with a 24V transformer , removing away the transformer from the interface or disconnect the transformer of the interface.

Scenario No. 2:
485 (P Q)or( S1 S2) communication inverter outdoor unit match with conventional other brand 24V indoor unit；

Match with following outdoor units ：

• Cassette (Sizes 36K~48K) Ducted (Sizes 36K~60K) Floor ceiling (Sizes 36K-60K)

NOTE:

•  T1(Room temperature) sensor should be located in the air inlet side.
  Must remove the TXV or other throttl-ing device from the indoor.

NOTE:

•  T1(Room temperature) sensor should be located in the air inlet side.
• Must remove the TXV or other throttl-ing device from the indoor.

Key Considerations

• The following steps should be taken when using this device with a conventional central air conditioning unit:
• Indoor coil metering device must be removed. 24V transformer in the interface module must be disconnected.
• Refrigerant charge amount may need to be adjusted, depending on the pipe size and length, see outdoor recharge instruction. The maximum air flow should not exceed 400 CFM/Ton.
• When the indoor air handler or furnace has its own 24 vac transformer, you must disconnect all four wires of the kit transformer.

Suction and liquid refrigerant lines must be properly insulated to prevent condensation and energy loss.

•  You must remove the expansion device from an indoor evaporator coil as the refrigerant is controlled by a metering device in the outdoor unit.
• The following steps should be taken when using this device with a Hi wall (9K-36K Btu/hr) Cassette, Console, Duct, Floor Ceiling (9K – 24K Btu/hr).
• Power switch on new board is changed. Indoor unit power switch setting, ENC-1 must be changed to the proper motor wattage: Eg. 36K = 8 48K = 9
