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 Test Run

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 - Switch SS1 to Emergency Setting Wire E 1 2 3

Outdoor PCB - Switch Emergency Switch 1 to ON All Earth Live Neutral Comms

Outdoor PCB - Switch Emergency Switch 2 to Cool or

Sensor Resistances – Use to check Thermistor

Air and Pipe sensors apply to indoor AND outdoor units. Sensor At 10C At 20C At 30C

The discharge sensor is only in the outdoor unit. Air Sensor 40K 0hms 25K 0hms 16K 0hms

If the fault code suggests the sensor is a problem but you Pipe Sensor 40K 0hms 25K 0hms 16K 0hms

get a sensor reading as to the right then either the connection Discharge Sensor 480K 0hms 293K 0hms 184K 0hms

or PCB is at fault.

For models CU3E23 & CU4E27 only there is a Green LED which normally flashes
