TIPS FOR SAVING ENERGY

Here are some tips that will help you minimize the power consumption when you use the air conditioner. You can use your air conditioner more efficiently by referring to the instructions below:

• Do not cool excessively indoors. This may consume more electricity.

• Block sunlight with blinds or curtains while you are operating the air conditioner.

• Keep doors or windows closed tightly while you are operating the air conditioner.

• Adjust the direction of the air flow vertically or horizontally to circulate indoor air.

• Speed up the fan to cool or warm indoor air quickly, in a short period of time.

• Clean the air filter once every 2 weeks. Dust and impurities collected in the air filter may block the air flow or reduce the cooling / dehumidifying functions.

INSTALLATION

Installation of Remote Controller

• After fixing the remote controller installation plate on the desired location, fix it firmly with the provided screws.

- If the installation plate is not flat on the surface, it may result in the controller being twisted and cause a defect.

- If there is a mounting box, install the remote controller installation plate using the fixings holes which suit, as in the below diagrams.

- Do not leave a gap with the wall or product loose after the installation.

• The wired remote controller cable can be installed in 4 directions. Install to the suitable direction according to the installation environment.

- Installation direction: Rear entry, top side, right side, left side.

- When you install the remote controller cable at the top, right and left side, remove the remote controller cable guide hole before the installation. ※ Use a long nose pliers to remove the guide hole.

• After removing the hole, trim the cut surface neatly.

INSTALLATION

• After fixing the remote controller top side on the installation plate attached to the wall as in the following figure, press the bottom side to combine with the installation plate.

- Do not leave a gap in the top, bottom, left, and right side of the remote controller and the installation plate after combining them.

- Before combining with the installation plate, arrange the cables to avoid interference with the circuit parts.

Wall Wall

•

When you remove the remote controller from the installation plate, insert a small flat head screwdriver into the bottom side separation hole and turn clockwise to separate the remote controller.

- There are 2 separation holes at the bottom part. Slowly separate one by one.

- Be careful not to damage the internal parts during the removal.

Wall Side

• Use the connection cables to connect the indoor unit with the remote controller.

ENGLISH

•

When installing the remote control cable on the left side, be sure to install it in the following guide.

1. Make the cable to "ㄱ" shape as shown below.

2. Fit the bent "ㄱ" cable into the upper center piece of case.

3. Tighten the installation plate with preventing interference with the surrounding guide structure.

※ If the cable is assembled in a shape other than "ㄱ", it may not be fastened to the installation

plate due to interference with the structure of case.

Please check if connector is normally connected.

Connecting cable

Indoor Unit side

• For the following cases, separately purchase and use the cables suitable for the situation.

- Do not install the cable over 50 m. (It may cause communication issues.)

- If the distance between the wired remote controller and the indoor unit is 10 m or more : 10 m extension cable (model name: PZCWRC1)

- If you control several indoor unit products with one wired remote controller : Group control cable (model name: PZCWRCG3)

NOTE

During the wired remote controller installation, do not bury it in the wall. (It may cause temperature sensor failure.)

Do not install the cable over 50 m. (It may cause communication defect.) When you install the extension cable, carefully check the direction of the connectors on the

remote controller side and the product side before the installation. Specification of extension cable: AWG 24, 3 conductor or above.

controller connector

While No. ① cable is connected, connect No. ② cable.

NOTE

• Connect only GND and signal cable to the indoor unit set as slave. (If power cable is also connected, it may cause loss of communication)

• Inquiries related to the purchase of the cable shall be directed to the specialized company and the service center.

• Change master/slave of the indoor unit.

- For Hydro Kit change the setting with the indoor unit PCB switch.

INSTALLATION

- After completing the master/slave setting in the indoor unit product, turn Off the power of the indoor unit product, and turn On the power after 1 minute.

NOTE

• During the group control, set only 1 indoor unit as master.

• Indoor unit(Hydro Kit)’s group setting is possible which connected same outdoor unit.

• In case of Group Control, it is possible to use following functions.

- Selection of operation options (operation/stop/mode/set temperature)

- It is not possible at some functions.

• During the individual control, if the master indoor unit DIP switch is set to slave, malfunction may occur.

2. You can use two wired remote controllers for one indoor unit.

• A dedicated cable must be used for the connection. If necessary, use an extension cable additionally and install. (2-Remo cable : PZCWRC2, Extension cable : PZCWRC1)

• For normal operation, one should be set as master and the other as slave. (Refer to the function "Installation setting - RMC master/slave")

• After completing the RMC master/slave setting, turn off the power of indoor unit, and turn on the power after 1 minutes.

ENGLISH

INSTALLATION

• If you set as Master-Master or Slave-slave for both remote controllers, the following pop-up is displayed once within 10 minutes after power-on.

If you use the 2-remo function, through the master remote controller you can check the temperature where the remote controller set as slave is installed.

The room temperature icon changes. This means that the value is detected by the slave remote controller.

INSTALLER SETTING

• Tank setting 1, 2 Descriptions for each parameters are as following.

- Min temp. : temperature gap from Max outdoor temp.

- Max outdoor temp. : maximum temperature generated by AWHP compressor cycle.

- Example : If Min temp. is set as ‘5’ and Max outdoor temp. is set as ’48’, then Session A (see

the graph) will be started when the water tank temperature is below 45 °C…. If temperature is above 48 °C…, then Session B will be started.

- Hysteresis : temperature gap from target DHW temperature. This value is required to frequent

On and Off of water tank heater.

- Heating priority : Determining heating demand priority between DHW tank heating and under

floor heating.

- Example : If user’s target temperature is set as ’70’ and Hysteresis is set as ‘3’, then the

water tank heater will be turned off when the water temperature is above 73 °C. The water tank heater will be turned on when the water temperature is below 70 °C.

- Example : If Heating priority is set as ‘DHW’, that means heating priority is on DHW heating,

DHW is heated by AWHP compressor cycle and water heater. In this case the under floor can not be heated while DHW heating. On the other hand, if the Heating priority is set as ‘Floor heating’, that means heating priority is on under floor heating, DHW tank is ONLY heated by water heater. In this case the under floor heating is not stopped while DHW is heated.
