1. Precautions

1-1 Precautions for the Service

● Use the standard parts when replacing the electric parts.

- Confirm the model name, rated voltage, rated current of the electric parts.

● Repair the disconnection of HARNESS securely when repairing the break down.

- If there is any connection error, it causes an abnormal noise and incorrect operation.

● In case that you assemble or disassemble the products with laying it on the side, do work on the work cloth.

- If not, the exterior of products can be scratched.

● Remove dust and foreign materials from harness, connection part, and inspection part thoroughly when repairing the break down.

- It protects the danger of fire such as tracking and short.

● Check the assembly status of parts after repairing the break down.

- It should be same as the status before repairing.

1-2 Precautions for the Safety

● Do not pull any electric wires and do not touch an auxiliary power switch with a wet hand.

- There is a danger of electric shock or fire.

● In case any wire or power plug has been damaged, replace it to eliminate any possible danger.

● Do not bend the power cord by force and do not put any heavy object on the power cord.

- There is a danger of electric shock or fire.

● Ground the product if necessary.

- Be sure to ground the product if there is any danger of electric leakage due to water or moisture.

● Be sure to turn off the auxiliary power switch or pull out the power plug during replacement or repair of electric parts.

- There is a danger of electric shock.

2-1 The Feature of Product

2-1-1 Features

 After 11 years, the introduction of the new technology used in the new products required the development of the control part.

– Global 4Way : 4-directional individual control, sensors that detect human presence, automatic cleaning and S-Plasma ion, etc.

– ERV PLUS, AHU : Humidification, supply of outside air and clean-up, etc.

 Integrated control between systems is necessary due to the growth in the market for ventilation products.

– Remote control integrated between the air conditioner and ERV products is necessary.

– Energy saving is realized through interlocking control.

● When installing a Wired Remote Controller by using a cable longer than 10m, you must install the communication cable and the power cable separatery. (Electrical interference can cause your Wired Remote Controller to malfunction.)

● When installing your Wired Remote Controller on the wall, consider the size of the wire hole, and select a wire with a proper thickness.

● Wire that is connectable to Wired Remote Controller PCB.

- If you install the Wired Remote Controller by reclaiming, install it according to U-terminal cable specification.

- If you install the Wired Remote Controller by using four pieces of PVC wire, remove the 30cm of the sheath of the cable and install it only with the four pieces of wires. (Recommended specification: AWG21)

2-4-2 Tracking Your Indoor Unit from the Wired Remote Controller


Indicates tracking in progress

Displays the total number of units searched

1. Tracking of your Wired Remote Controller will automatically start when you turn on the power after installation.

2. If you want to perform tracking again after installation, then press the Esc and Delete buttons at the same time for more than five seconds.

● The system will reset, and tracking will start again.

3. During tracking, the total number of currently searched indoor units and ventilator(ERV) will be displayed.

● If you want to perform tracking again after installation, then press the Esc and Delete buttons at the same time for more than five seconds.

● Only the master Wired Remote Controller can display the total number of indoor units and ventilator(ERV).

- Slave Wired Remote Controllers do not display the total number of units.

Image Procedure

Push the2 fixing structures at the bottom inwards, and then pull up the front cover to separate it from the rear cover.

(This step is easy when using a flathead screwdriver.)

When assembling, assemble the upper part first as in the

picture, and then insert the bottom hook.

2 Separate the door cover by pushing the bottom-right part of the product sideways.

For assembling or dismantling, leave the door cover

open about 130 degrees as in the image to do the work.

Otherwise, the hinge may be incorrectly assembled,

resulting in faulty operation.

(When communication has stopped for 3 minutes after detecting indoor unit/ventilation system

(ERV) and wired remote control)

Tracking 10 or more errors between wired remote control ↔ indoor unit/ventilation system (ERV)

- COM1, COM2 crossing connection error

- When wired remote control is connected to indoor unit COM1 (F1, F2) terminal

- Multiple master error

- Error occurred during installation when two wired remote controls are both set as masters in one communication line (This is not possible to detect if the communication polarity is connected in reversed polarity.)

Remark

When using master remote control

Ventilation system (ERV) is not installed in case of outside gearing.

Indoor unit is not installed in case of outside gearing (when the indoor unit is not detected after outside gearing option setting and tracking are finished).

- Exceeded maximum no. of installation for indoor unit/ventilation system (ERV) (16 equipment devices)

- A reset is required after checking the number of indoor unit/ventilation system (ERV) installations

Can be connected by both master and slave wired remote controls

In case of using outside gear control

- Mixed installation error for °C/°F indoor unit

- Error occurs when mixed indoor units of °C and °F settings are installed

Only detected by the master wired remote control

- Wired remote control °C/°F setting error

- This error occurs if the indoor unit is set in °C while the wired remote control is set in °F or vice versa.

This error occurs when the option settings of the master and slave wired remote controls are different from each other.

Slave wired remote control installation error (when two slave wired remote controls are installed)

Normal operation option setting error (when normal operation is selected with the wired remote control for a ventilation system (ERV) that does not support the normal operation option)

Automatic operation option setting error (when automatic operation is selected with the wired remote control for a ventilation system (ERV) that does not support the automatic operation option)

Temperature sensor open/short error

Only detected by products with a temperature sensor

- FRAM READ/WRITE error

- Damper error [error is detected when there is no input for 100 seconds (time for about 5 revolutions) during damper output]

● Please refer to the Installation guide of each equipment device for the error codes used for the indoor unit, the outdoor unit, and the ventilation system (ERV).
