How to select the room temperature sensor
(Fig. 1)
To installation personnel - Electrical work and ServiceINSTALLATION MANUAL Remote controller with weekly timer Model: RBC-AMS41UL
Install the remote controller 3'3" to 4'11" (1 m - 1.5 m) above floor level (average room temperature area).
Do not install the remote controller in a place exposed to direct sunlight or outside air (such as a window, etc.).
Do not install the remote controller where ventilation is poor. Do not install the remote controller in a freezing or refrigerated area - the
remote controller is not water or splash-proof. Install the remote controller in a vertical position.
Be sure to follow the installation dimension as shown in the figure 1 when you install the remote controller on the wall.
Two room temperature sensors are installed: one in the indoor unit; the other in the remote controller. Only one sensor (usually the indoor units) can be active at any one time. To select the sensor in the remote controller, perform the following steps. 1.Push + temperature setup button for 4 seconds or more. NOTE:The unit number displayed the first time is the indoor unit address of
the master unit in the group control. NOTE:Do not press the button. 2.Using the temperature setup buttons / , specify the item code . 3.Using the timer buttons / , change the setting from to . 4.Push the button. (The display should stop flashing and become
constantly lit.) 5.Push the button. The status returns to the operation stop status and is displayed in the
LCD. NOTE 1:When using two remote controllers, the room temperature sensor
selection can be set either from the header/follower remote controller. Only the header remote controller can act as a remote control sensor. When using two remote controllers, the temperature can be set from either the header or follower remote controller.
NOTE 2:In group control, the remote control sensor does not work if the group address is not set to the indoor unit of the master unit.
NOTE 3:When using the remote sensor and the remote controller together, do not use the remote control sensor of the remote controller.
In a dual remote controller system, one or more units are operated by multiple remote controllers. (A maximum of two remote controllers can be set.)
How to install For a dual remote controller system, install the remote controllers in the following way. 1.Set one of remote controllers as the header remote controller. (The default
setting is Header.) 2.Set the DIP switch on all other remote controller P.C. boards to Sub (to enable
them as follower remote controllers).
1.For removal of the remote controllers lower case (rear case), insert the tip of a straight blade screwdriver, etc., into the two openings at the bottom of the remote controller to open the lower case.
2.Fix the remote controllers rear case by wood screws (2 pcs.). Do not over tighten, as it may damage the rear case.
3.Connect the wires from the indoor unit to the remote controller terminal block. (Refer to How to wire the remote controller.)
Connect the wires of the remote controller following the terminal numbering convention of the indoor unit to prevent miswiring. (Do not apply AC 208-230V mains voltage to the remote controller as it will be damaged).
NOTE 1:The remote controller wire should not be bundled with other wires (mains, etc.), or installed with other wires in the same conduit, as malfunction may result.
NOTE 2:Install the remote controller away from sources of electrical interference and electromagnetic fields.
NOTE 3:If electrical interference is unavoidable, countermeasures such as appropriate filtering should be employed.
Operating a group control of multiple indoor units from remote controllers installed in two different locations. * Header and Follower remote controllers are operable even if they are
connected to any indoor unit.

1.Push and hold the button for 4 seconds or more until TEST appears in the LCD, then press the button. TEST appears in LCD during the test run. Temperature adjustment is not possible while TEST is displayed. The test
run applies considerable load on the machine; therefore, it is recommended not to use the test mode beyond necessity.
2.The test mode should be used in either HEAT or COOL mode. NOTE:The outdoor unit will not operate for approx. 3 minutes after power up,
or the operation will stop. 3.Be sure the TEST indication in the LCD has disappeared by pushing the button again after exiting the test mode. (The remote controller has a
60-minute off timer function to prevent continuous test run).
Remote controller test run setup
Follow the steps below to select and set the operation status of the air conditioner when power is restored after a power outage has occurred during a scheduled operation. 1.Hold down the + buttons for at least 4 seconds. (This step can be
performed whether the air conditioner is running or shut down.) 2. Press the TEMP. / buttons, and set code No.14. 3. Press the TIME / buttons, and set the setting data to (factory
setting) or . 4. Press the button. The setting data is entered successfully if the display
stops blinking and lights up. 5. Press the button. * (factory setting): No settings are sent when the power is restored, and the scheduled
operation is resumed as soon as the program time is reached after the power has been restored.
* :If there was a program which was to have run during the power outage, it is resumed in accordance with what was programmed. If there is no program, operation resumes in accordance with what was being performed prior to the power outage.
