If a heat pump model is being used, it will beep twice and the operating lamp will light up on the display; if the timer and standby lamps blink alternately, a conflict between the heating and cooling exists, so the unit cannot operate in the desired mode. (On models that do not have an
Auto function, even if Auto is selected, it works in the same way.) When the local operation is disabled by such as the centralized control, and if the Start, Stop, Mode or Temperature setting buttons are pressed, the unit will beep five times and the change will not be made.
3. Installing Batteries
1. Remove the cover. 2. Insert two AAA alkaline batteries. Put the batteries in with the polarity [+/–] as shown in the figure.
3. Gently insert one end of an unfolded paper clip
(or a similar object that can fit) into the Reset hole and press the reset button inside the hole and then put the cover back on.
Change the batteries when the display of the remote control gets weak or if it will not work unless close to the receiver.
(Alkaline batteries generally last about one year.) When changing batteries, always use two fresh batteries of the same make. If the remote control will not be used for a long period of time, remove the batteries. Please dispose of batteries appropriately. After changing the batteries, follow the procedures on the next page to reset the current time.
EN HOW TO REMOVE BATTERIES

If you cannot turn the air conditioner off in the normal way.
Disconnect the power to the indoor unit and contact the dealer where the product was purchased.
If all the indoor units are identical in a cooling system and are under control as one group, it heats or cools automatically via the differences between the set temperature and the room temperature.
• Depending on the indoor unit used, the remote control may have a [Dry] indicator on its display even though the unit does not have the Dry function. (Same as cooler operation) • When the room temperature approaches the temperature setting, the unit continues to start up or stop automatically. • When the drying mode stops operating, the indoor unit’s fan blows a gentle breeze in order to keep the moisture from returning to the room at a minimum. • Depending on the indoor unit used, and/or the temperature in the room, the fan speed may not be adjustable. • Depending on the unit used, when the outside air temperature is 15 °C or less, the dry function will not operate.
• When setting the timer, make sure the current time on the remote control is accurate. • The timer’s clock can only be set when the display of the remote control is ON. • After setting the timer, put the remote control in a place where its signal will reach the receiver of the indoor unit.

7. Adjusting the Wind Direction (Cont.)
CZ-RWSC3 The available functions differ depending on the indoor unit being used. The wind direction cannot be set via remote control for any models other than those noted below. For more information, please refer to the users’ manual that came with your indoor unit.
Four-direction Ceiling Cassette Models, Bi-directional Ceiling Cassette Models,
Unidirectional Cassette Models for High Ceilings, Ceiling Suspended Models, Wall Models Please refer to Setting the Wind Direction and Stopping Flap Swing.
8. Operating Multiple In/Outdoor Units Simultaneously
Group control works well for providing air conditioning to one, large room with more than one air conditioning units.
• One remote control can operate up to eight indoor units.
• All the indoor units have identical settings. Receiver • Set temperature sensing to the indoor unit (Main Sensor). (See Pages I and II)
Wireless Remote Control
9. Using the Remote Control
• Point the transmitter of the remote control at the receiver. When the signal is received correctly it will beep once. (It beeps twice only when the unit starts operating.) • The signal can be received at a distance of about 6 meters. This distance should be used only as a guide. It depends on battery strength. • Make sure nothing is between the remote control and the receiver that could block the signal. • Do not leave the remote in direct sunlight, where the wind from the air conditioner can blow directly on it, or near any other heat source. • Take care not to drop, throw or wash the remote control with water. • The signal from the remote control may not be received in rooms with rapid start fluorescent lighting, inverter lights, plasma displays, LCD televisions (monitor), etc. For more information, please contact the dealer where the product was purchased.
• Press from the location you wish to mount the remote and make sure the signal is received correctly. • Pull the remote control forward to remove it.
Fasten the remote control mount with screws.

10. For Best Results
Don’t get the remote control too far away from the receiver. This may cause a malfunction. Be sure to keep the remote control in the same room as the receiver.
Point the remote control at the receiver.
When the signal is received correctly it will beep one time.
Avoid locating the remote control where it is covered, such as behind a curtain.
Keep it out in the open.
In both multi and single unit installations, when more than one indoor unit is installed in the same room with a compatible remote control, addresses can be set up to avoid crosstalk. By setting the address switches on the receivers and matching them with the number of addresses on the remote control, up to six indoor units can be controlled separately with the remote control. (When using units in a flexible combination or operating multiple units simultaneously, as they are operated at the same time, they cannot be controlled individually.) There are separate address settings, receiver addresses for the receivers*1 and transmitter addresses for the remote control. For more information, please contact the dealer where the product was purchased. • The setting procedure is different for CZ-RWSY2 and Indoor Unit (CZ-RWSK2). (See Page EN-16) • These settings are saved in nonvolatile memory in the remote control, so even when its batteries are changed, the settings do not have to be made again. *1 CZ-RWST2/CZ-RWST3 is of receivers (Inside the indoor unit); CZ-RWSL2 is of an operation panel. (Inside the indoor unit)
When you press on the remote control, its current address is shown in the display. If this address corresponds to the address of a receiver*2, the buzzer sounds. (If it is on ALL, the buzzer will always sound.) If it is on ALL, it can be operated regardless of receiver addresses. Point the remote control at the receiver you wish to operate and transmit. *2 CZ-RWSL2 is a receiver (Indoor unit)
