Not Operating: 

 

# Check the wiring configuration from the outdoor unit to the indoor unit. Is it wired up 
correctly in accordance to the wiring diagrams provided on both indoor & outdoor units? 
(Refer page 28) 

# While the unit is in “standby” mode, check if the red stand by light is on? 

# Try operating the unit by the forced operations button: By pressing the button once, the 
unit should activate in Auto mode. Pressing it twice will turn the unit off. 

# If the unit can be operated by the forced operations button & the red stand by light was on, 
check the remote controller. 

# If the unit can be operated by the forced operations button & the red stand by light was off, 
replace the display PCB assembly. 
# If the unit cannot be operated by the use of the remote control or the forced operation 
button, check for supply voltage at the following points, illustrated on the next page. 

 

 

Standby indicator on Display PCB assembly.
