ECO: After eco is enabled, the home page will show a icon ” “. Upon receiving the ECO command, the IDU will initiate the ECO mode. It will modify the current setpoint threefold. The initial adjustment will increase the setpoint by 1° after the IDU has been in ECO mode for over 1 hour. Subsequently, each adjustment will change the set temperature by 1° every hour.
In cooling mode, the IDU will increment the setpoint by 1° every hour,
24

while in heating mode, it will decrease the setpoint by 1° every hour. For instance, if the setpoint is 20° in cooling mode, it will become 21° after 1 hour, then 22° after an additional hour, and finally 23° after the last hour.
The IDU internally handles the adjustments to the set temperature, and these changes won’t be displayed in the controller’s interface.
Sleep: After sleep is enabled, the home page will show a sleep icon. The sleep function is only applicable to cooling and heating modes and unavailable for auto, dry and fan modes. With sleep enabled, it will be cancelled after manual power-off or mode switching. You have to re-enable this function.
During cooling mode operation, the Indoor unit will set the temperature to preset 25° and incrementally raises it by 1° each hour. This temperature adjustment occurs twice, resulting in a final temperature of 27° for the subsequent 6 hours.
In heating mode, the indoor unit sets the temperature to a predetermined 22° and subsequently decreases it by 1° per hour. This two-step adjustment culminates in a temperature of 20° for the remaining 6 hours.
Users have the flexibility to modify the preset temperature at any point while the unit is in sleep mode. The indoor unit will promptly update both the set temperature and the preset sleep mode pattern to align with the adjusted settings.

Error codeC51

1. If any IDU or ODU fails, the wired controller displays the fault code. In case a communication fault occurs between the wired controller and any of the IDUs, the wired controller reports “C51”. This will not stop the entire system.
2. The wired controller can record up to 10 faults, each of which includes the address of the faulty device, the fault code, and the time when the fault occurs. 44

2.4 FAQ
The air conditioner is not working, but prompts that neither cooling nor heating option can be set. What should I do? The set mode is inconsistent with the operating mode of ODU. Please change the set mode to cooling/heating. The word “Filter” is displayed on the operation panel. What should I do? Into the WDC configuration settings and select the Filter reset’ option and pressO’ to confirm reset the filter blockage reminder. Refer to section 3.5.3 WDC Configuration on page number 64. The filter notification is depended both on running hours and pressure, the default hours and setting parameters is shown above.
45

What are the possible causes if the air conditioner is not running as strongly as it should be? Please check in the following sequence: 1. Whether the set mode is cooling or heating; 2. Whether the louvers of the air outlet face down; 3. Whether there is any barrier 20 cm around the IDU; 4. Whether the IDU is clogged and needs to be cleaned. 5. If the problem persists, Please contact your installer or
ActronAir.
Why does the air outlet of air conditioner drip? The indoor air humidity is too high. Please close the doors and windows. The Louvre position may also be too high – see the owners manual for your indoor unit for reference. Why does the ODU of air conditioner drip? 1. During cooling in summer, condensation water generated by
the unit is discharged to the outside through the IDU drainage pipe. If the drainage pipe is close to the ODU, the condensation water may be mistaken for the water leaked from the ODU. The ODU does not drain any water during cooling. 2. During heating in winter, the ODU may be frosted. Then, the unit will defrost and the defrosted water will flow from the drainage outlet at the bottom of the ODU. This is a normal phenomenon instead of a fault of the air conditioner. To deal with this, you may contact the after-sales personnel or the installer to install an ODU drainage pipe.
46

Why does air conditioner fail to start after it is powered on? In winter, it takes some time for your air conditioner to warm up. Please wait a few minutes.
Why does air conditioner keep operating after it is powered off? After air conditioner is powered off, it operates for a while to eliminate the moisture, so as to reduce the possibility of mould growth.
Why are the air conditioner functions non-adjustable? If the controller display panel shows the lock icon, then press both “<” and “>” at the same time to unlock the child lock – please refer to Child Lock section (page 38) of the manual.
If the lock icon is not indicating the child lock, it implies that the wired controller has been locked by the central controller. To unlock it, the action must be taken from the central controller. Alternatively, if the temperature or fan speed has been locked on the wired controller, accessing the engineering settings will allow for the unlocking of the temperature and fan speed locks.

3.4.2. Wiring
One-to-one/two-to-one system
Applicable to bi-directional communication between a wired controller and an IDU.
One-to-one system: One wired controller controls one IDU. Two-to-one system: Two wired controllers control one IDU. Parameters displayed on the wired controller vary with the parameters of the IDU. The data is updated in real time.
Communication cables between an IDU and a wired controller (X1, X2) may be connected in reverse order.
For a two-to-one system, one controller will be the master controller while the other will be the slave controller.

screws and wall plugs
i INFORMATION
Be careful not to distort the rear casing by overtightening the mounting screws.
54

NOTE
When mounting the rear casing to a flush-mounted electrical installation box inside a wall, make sure that that wall is completely flat.

Screw hole installed on 86 electrical box, use two M4X25mm

55

When installed on the wall: The wire can directed in four directions as shown below.
Cutting place of up,down,left and right side wire outlet
Up, down, left and right side wire outlet Lead the 2-core shielded cable through the wiring hole in the bottom cap of the wired controller, and use screws to reliably fasten the shielded cable onto terminals X1 and X2. Then fix the bottom cap of the wired controller onto the electrical box by using pan head screws.
56

NOTE
Do not perform wiring operations on energized parts. Make sure that you remove the wired controller before proceeding. Otherwise, the wired controller may be damaged. Do not overtighten the pan head screws; otherwise, the bottom cap of the wired controller may deform and cannot be levelled on the wall surface, which makes it difficult to install or not securely installed.

To avoid water entering into the remote ensure the cable has a loop to trap any water and ensure the wire entering the space is sealed.

Connect the wired controller and the rear cover as shown in the following figure.

58

When the control is correctly connected to the backing plate the wall control should sit flush to the wall as below.
NOTE
Make sure that no cables are clamped when buckling the wired controller and bottom cap. The wired controller and bottom cap should be installed correctly. Otherwise, they may get loose and fall apart.
