Panasonic Fault codes - FS Series


Fault Codes – FS Series
Current Models R410a
Pressing Check on the wired remote while CHECK is flashing will give the Fault and the address of the unit with the Fault
Pressing Timer Set with the fault displayed will display a second code giving further information (detail code)
Pressing Check for 5 seconds will check past faults
On wireless handsets press the temp up for 5 seconds to enter error check mod
Scroll through the codes using the temp up button until a beep is heard from the indoor unit
Press set and repeat until the full code is displayed

A General Guide To Urban Style Products

Pipework
• Pipe sizes and lengths should be as the relevant Technical Guide
• Both lines should be insulated
• No line accessories or oil traps should be fitted
• In cooling mode the suction line should sweat, but not freeze
• In heating mode both pipes should be between 30 and 60C
• Pipework should be refrigeration quality
• Look for restrictions. They could cause compressor failures.
Outdoor Unit
• Discharge Temperature should be between 50 and 70C
• Suction Temperature should be between -3 and 4C
• Check Suction Line is sweating in cooling - problem if not!
• Hot Recip. Compressor = PROBLEM
• Sweating/Frost on expansion line - undercharged
Indoor Unit
• Is it level? Have we adequate drainage?
• Smells are always due to site conditions or drains.
• Flashing lights? = Fault Diagnostics - see over
• When were the filters last cleaned?
• Is the unit too large/small (between 5/20 air circs/hr)
• Is the air short cycling?
Controller
• Is it a wired or wireless handset.
• Is the handset too far away?
• When were the batteries changed last?
• With wired handset, check for interference.
• Is the unit in Emergency Mode?
• Check unit and controller channels compatible
Wiring
• Interconnecting comms wiring is low voltage
• If you have 230V live, check you have a neutral as well
• Check Mains and comms cable not swapped round
• Multi linked systems must be set up as such
• Check voltage drops! Check it isn’t down to Earth!
• Interconnecting cables should be circular crimped


Selecting Emergency Mode is done at the Indoor and Outdoor Unit PCB.
It bypasses the Control Sensors and should not be done for more than 30 minutes.

Indoor PCB - Swicth SS1 to Emergency Setting
Outdoor PCB - Swicth Emergency Swicth 1 to ON
Outdoor PCB - Swicth Emergency Swicth 2 to Cool or

Wire E - 1 - 2 - 3
All Earth - Live - Neutral - Comms

Sensor Resistances – Use to check Thermistor
Air and Pipe sensors apply to indoor AND outdoor units
The discharge sensor is only in the outdoor unit.
If the fault code suggests the sensor is a problem but you
get a sensor reading as to the right then either the connection or PCB is at fault.

Sensor - At 10C - At 20C - At 30C
Air Sensor - 40K 0hms - 25K 0hms - 16K 0hms
Pipe Sensor - 40K 0hms - 25K 0hms - 16K 0hms
Discharge Sensor - 480K 0hms - 293K 0hms - 184K 0hms


Fault codes on Panasonic US systems can be checked using both the wired remote controller and the indoor and outdoor unit LEDs. In case of a malfunction
the wired controller will give a fault code as shown below in conjunction with the accompanying LED codes.
The wireless controller can be used to interrogate a fault, if required, as described below.
1 - Press Inspection/Test button on wireless handset. 0 flashes in Unit Number display on handset.
2 - Press Up/Down button until unit starts to bleep.
3 - 1 continuous beep means No fault. 3 short beeps - follow all steps below. 1 short beep - follow step 4 until you get a continuous beep.
4 - Press the handset MODE button. Press the up/down arrow button until you get 2 short bleeps, or one continuous bleep.
5 - Press the MODE button again. Press the up/down arrow button until you get one continuous bleep.
6 - The fault code is now displayed!
