IF REMOTE CONTROLLER DISPLAYS NOTHING
•
Check the power supply to the indoor unit.
•
Check once more that the remote control cable is securely connected.
(Check for loose terminals, poor contacts, connection positions on the terminal block, etc.)
•
If the above checks show that nothing is wrong but nothing still appears on the remote controller display, refer to
“Settings” in the installation manual that is provided with the indoor unit.
SETTING FOR 1 REMOTE CONTROLLER GROUP CONTROL
•
A maximum of 16 indoor units can be connected at the time of group control. (Do not connect the heat pump unit
with the cooling only unit.)
•
There are 2 methods for setting the group control address (A/C No.); an automatic and a manual setting method.
•
The A/C No. setting cannot be confirmed when using the automatic method.
•
To set each indoor unit’s A/C No., use the manual setting method.
However, if the wall type indoor unit is connected, then manual setting is not possible.
■ Automatic setting
•
By switching ON the indoor unit’s power supply with the DIP switch where the A/C No. is set to “01” (factory
setting), the A/C No. will be automatically set. (After activating the power for all indoor units, the automatic
setting takes approximately one minute.)
•
Once the A/C No. is automatically set, even when the power supply is switched OFF, the setting is stored.
To reset the A/C No. setting, follow the instructions for the “group control automatic address reset”. Refer to
the item “Local setting” in the installation instruction manual that comes with the wired controller for the
“group control automatic address reset” method.
* If the indoor unit’s A/C No. DIP switch is not set to “01”, the automatic setting cannot be reset.
■ Manual setting
•
The manual setting is performed using each indoor unit’s printed circuit board DIP switch. (Refer to the
diagram below)
•
Set the DIP switch once the power supply for each indoor unit is switched OFF. When the power supply is
turned ON, the stored A/C No. is recalled.
•
To change the setting of the A/C No., turn OFF the power supply before resetting the DIP switch.
* Ensure that there is no redundancy in the A/C No. Any redundancy can cause faulty control.
* Ensure to set the A/C No. to “01” for 1 indoor unit.
