Taking Power for a pump from the unit is a major source of Errors (CLIMATE CENTRE) 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 both pipes should be between 0 and 10C - the suction line should sweat, but not freeze • In heating moded both pipes should be between 30 an 60C • Pipework should be refrigeration quality • Refrigerant should be R22, unless stated on the outdoor unit • Look for restrictions. They could cause compressor failures. Outdoor Unit • Discharge temperature should be between 50 & 70C • Suction temperature should be between -3 & 4C • If fan switches off check for high discharge temperature • Check Suction Line is sweating – 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 it on Timer/Test Mode Controller • EE:EE on LCD handset - fault diagnostics - see over • Is the handset too far away? • When were the batteries changed last? • Heat Pump models 7-14 – NOT auto changeover • Timer is one shot, unless it has ‘repeat’ mode • With wired handset, check for interference. Cable should be screened • Is it on Timer/Test Mode Wiring • In general interconnecting wiring is 240 Volt, but see chart for details • With LCD wired handset models, Terminal 3 is the Live Not Terminal 1 NEVER apply mains voltage to Terminal 1 on these models • With LCD wired handset models wiring should be screened • Check Voltage drops! Check it isn’t down to Earth! • Has it got a timeclock/BMS interface? • Interconnecting cables MUST be circular crimped What the separate Wires do in the interconnecting Cables Note – Wires are 240V Live except where marked neutral or Earth or signal Cables marked Signal are digital pulses and you should not attempt to measure these with a meter. Wired Controllers - Fault diagnostics A Fault Condition is signalled by EE:EE appearing on the LCD panel. The unit should be interrogated by switching it off on the handset then pressing either the down arrows on the SET TIME and TEMP/DAY buttons together for 3 seconds for 7 day models or the ENERGY SAVE & ZONE CONTROL buttons for other models. The Failure code is in 2 parts - Fault and Address. The Fault Code is an E code. The second is the unit address for multi linked systems - with single units this is always 00. 7 day models have the fault code as shown in the table below above the address. Other models have the codes below, minus the 0, followed by the address - e.g. E9:00 denoting Float Switch on Unit 0. Code = E:0 Fault = I/U - R/C Comms Diagnosis = Check R/C wiring. Interference? Code = E:01 Fault = I/U - O/U Comms Diagnosis = Check intercon. wiring.

Code = E:14 Fault = Outdoor PCB Fail Diagnosis = PCB Failure Outdoor Unit with A fault condition is signified by flashing red LED’s on the the outdoor PCB if it is equipped with one. Except for multisplits and 2 LED models, the diagnostics are shown in the table on the right. For 2 LED models flashing signifies sensor failure and constantly lit indicates high discharge temperature.
