WARNING

• Basic priority: Central control and wireless remote control will operate normally. If the indoor unit is controlled by central control or wireless remote control, the displayed indoor status on the thermostat and the actual status of the indoor unit may be different.
• Thermostat priority: The thermostat control will be applied first and will control the indoor unit based on the thermostat demand. Indoor units with this option set to ON will ignore wireless remote control and central control commands including central controller schedule, logic control, etc. Central controllers will only monitor indoor unit status.

Off On On Blinking Off					Error in the installation of multiple indoor units
On Off On Blinking Off					External thermistor error (External NTC Error)
Off Off Blinking Blinking Off					Abnormal thermostat signal (Abnormal W,Y Signal)
Off On Blinking Blinking Off					Abnormal thermostat signal (Abnormal W,Y Stage1,2 signal)
On Off Blinking Blinking Off					Abnormal thermostat signal (Abnormal G, G1, G2, G3 Signal)
On On Blinking Blinking Off Dry contact Input (Close)

Resetting custom settings

To reset the Thermostat Kit settings, press the (SW5) button inside the kit.

When pressed the Thermostat Kit resets then enters "initial mode", and then returns to normal operation.

Troubleshooting

Symptom Measure
The thermostat kit does not work at all.(No LED lighting)	Check the power supply wiring (AC 24V).This connects to F3/F4 enabling central control should not matter.
Cooling does not work. Check the wirings for power supply (AC 24V) and communication.
Heating does not work. Check the wirings and options for power supply (AC 24V) and communication.
The desired fan operation does not match.	Check the option setting.
The thermostat temperature setting is different from that of the thermostat kit.	Check the rotary switch setting.
