Panasonic CZ-RWSY1U Installation Manual
Warnings about Installation of Receivers
The wireless remote uses a very weak infrared light for its signal, which can result in the z
signal not being received because of the following infl uences, so take care in where the unit is
installed.
Inverter or rapid-start type fl uorescent lights. (Models without glow lamps)•
Plasma display or LCD televisions.•
Direct sunlight or other sources of bright light.•
Warnings about Installing Remote Controllers
If a remote controller is to be operated from a remote control holder that is hung on a wall, turn z
on the lights in the room as well as any electrical appliances and then check to make sure the
air conditioner works with the remote controller in the location where it will be installed. If it
works, continue with installation.
If the air conditioner is to be switched from the main sensor to a remote control sensor, pay z
attention to the following when installing.
Locate where no warm or cold drafts will affect it.•
Locate in a place free from direct sunlight.•
Locate where it will not be affected by any other heat/cold source.•
Customer Explanation
Give the Operating Instructions and this manual to the customer after fi nishing the installation. z
Use the Operating Instructions to explain to the customer how to use and care for the unit. z
Things to remember when wired and wireless remotes are
installed at the same time
Two remote controllers can be used to control the unit if the wireless remote controller is installed
at the same time as the wired remote controller.
(Up to 2 remotes [a wireless remote controller and the wired remote controller] can be installed.)
When using 2 remotes, one or more units can be operated by the remotes.
<Note> When wiring remote controllers, be sure to double-check the terminal numbers of the
indoor unit before connecting them so there are no mistakes in the wiring. (Damage will
occur if high voltage [e.g. supply voltage] is applied.)
<Note> It is not possible to use more than one wireless remote controller with one indoor unit.
(A receiver located separately can be used at the same time.)
<Note> If both a wireless and a wired remote controllers are to be installed and used at the
same time, one of them must be set up as the sub remote controller.
If the wired remote controller is to be the sub remote, change the wired remote controller to the z
sub remote.
If the wireless remote controller is to be the secondary, turn the switch on the wireless receiver z
from [MAIN] to [SUB].

Room Temperature Sensor Settings
Common to All Models
The indoor unit and the wireless remote controller are equipped with indoor temperature z
sensors. The sensing of indoor temperature works via one of them.
When the unit is shipped, it is set to the indoor unit, but to switch to the remote controller, press z
the sensor button (diagram at right) inside the remote controller’s cover and then check to
make sure that Main Sensor on the LCD screen goes off.
<Note> Even when the sensor switch has been set to the remote controller, if the unit does
not receive any room temperature data from the remote controller for ten minutes, it
automatically switches back to the indoor unit sensor, so be sure to install the remote
controller facing the receiver.
Setting Up Remote Control Functions
The functions of the wireless remote can be set on site.
(These settings are saved in nonvolatile memory in the remote controller, so even when its batteries are changed, the settings
do not revert to the defaults.)
<Note> The operation of the air conditioner can be impacted, depending on the settings made, so only service personnel
should make the settings.
Furthermore, making changes to these settings may cause actual operation to deviate from what is printed in the
Operating Instructions, so be sure to explain this to the customer fully.
Making Settings (Do with unit stopped.)
Holding down the Swing/Wind Direction + OFF Timer 1. + Mode Select buttons at the same time for 4 or more seconds
makes the display switch to the setting screen. (See Diagram Below.)
Use the Temperature setting buttons, 2.
/ , to select the number of the item to be set.
Use the ON Timer buttons, 3.
/ , to change settings.
The settings are saved with the Once/Every Day button. When this is done, the settings display of the LCD changes from 4.
blinking to light.
If other settings are to be changed as well, repeat steps 2 to 4.5.
When all settings have been made, press the Start/Stop button.6.
