VII. Test Run by the Remote Controller (for Mr. SLIM P Series)
1. Check Points Under Test Run
Before test run
• After installation of indoor and outdoor units, piping work and electric wiring work, re-check that there is no refrigerant leakage, loosened connections and incorrect polarity.
• Measure impedance between the ground and the power supply terminal block(L1, L2) on the outdoor unit by 500V Merger and check that it is 1.0M
Don't use 500V Merger to indoor/outdoor connecting wire terminal block(S1, S2, S3) and remote controller terminal block (1, 2).
This may cause malfunction.
• Make sure that test run switch (SW4) is set to OFF before turning on power supply.
• Turn on power supply twelve hours before test run in order to protect compressor.
• For specifi c models which requires higher ceiling settings or auto-recovery feature from power failure, make proper changes of settings referring to the description of Selection of Functions through Remote Controller.
Make sure to read operation manual before test run. (Especially items to secure safety.)
2.Test Run using the Wired Remote Controller

[TEST] button
Operating procedures
1. Turn on the main power supply.
2. Press TEST button twice.
3. Press OPERATION MODE button.
4. Press AIR DIRECTION button.
5. Check the outdoor unit's fan is rotating.
6. Press the ON/OFF button to reset the test run in progress.
While the room temperature display on the remote controller is “PLEASE WAIT”, the remote controller is disabled. Wait until “PLEASE WAIT” disappears before using remote controller. “PLEASE WAIT” appears for about 2 minutes after power supply is turned on. 1
The TEST RUN appears on the screen.
Cooling mode: Heating mode: Check if warm air blows. (It takes a little while until warm air blows.)
Check for correct motion of auto-vanes.
The outdoor unit features automatic capacity control to provide optimum fan speeds. Therefore, the fan keeps running at a low speed to meet the current outside air condition unless it exceeds its available maximum power. Then, in actuality, the fan may stop or run in the reverse direction depending on the outside air, but this does not mean malfunction.
Check if cool air blows and water is drained.
7. Register the contact number.(Refer to V.4.3.3.)
Pipe (liquid) temperature
• In case of test run, the OFF timer will be activated, and the test run will automatically stop after two hours.
• The room temperature display section shows the pipe temperature of indoor units during the test run.
• Check that all the indoor units are running properly in case of simultaneous twin and triple operation. Malfunctions may not be displayed regardless of incorrect wiring.
1 After turning on the power supply, the system will go into startup mode, "PLEASE WAIT" will blink on the display section of
the room temperature, and lamp(green) of the remote controller will blink.
As to INDOOR BOARD LED, LED1 will be lit up, LED2 will either be lit up in case the address is 0 or turned off in case the

VARIETY OF SYSTEM FUNCTION
System Name System Diagram Features
There are two types of remote controllers: wired type and wireless type. Simultaneous twin units are counted as one unit, and the indoor units are started or stopped
simultaneously.
Up to two remote controllers can be connected to one group. Simultaneous twin units are counted as one unit.
Operation control by the latest command (last en­tered priority) Wired and wireless remote controllers can be com­bined as a pair.
One group can consist of up to 16 indoor units, and they can be started sequentially by connecting the remote controller to them and assigning an address to each outdoor unit. Simultaneous twin units are counted as one unit. All the units belonging to the same group are oper­ated in the same mode, but thermostats can be turned ON/OFF individually for each outdoor unit. Up to two remote controllers can be connected.
All the air conditioners can be turned ON/OFF collectively from a distance. Operation can be switched between the remote operat­ing panel and local controller. Operations (e.g., temperature adjustment, airflow, air­flow direction) except for start/stop operations can be performed even if the operations from the local remote controllers are prohibits. In the case of simultaneous twin units, connect the controller to one indoor unit only. If connected to two or more indoor units, an error (operation stop) may occur. Control by an external timer is possible by connecting it.

In the case of free component multi type systems consisting of simultaneous twin units, connect two wireless remote controller receivers (one each) to any two of the indoor units. All the functions of the connected indoor units can be controlled even if the system consists of different models. In the case of free component multi type systems consisting of simultaneous twin units, the indoor units should not be connected by crossover wiring. (Prohibited) In the case of "standard 1:1" connection, it is not possible to connect two remote controller receivers to the indoor units. However, with systems consisting of simultaneous twin units, it is possible to connect a remote controller receiver to two indoor units. In this case, all the pair numbers will be "0"(factory setting, no change necessary), and all the units will be turned ON/OFF simultaneously. When using two or more wireless remote controllers, the display contents on the remote controllers may differ from the actual settings, since the operation made last by any of the remote controllers will be effective.
