5 Electrical diagram KFHHP-22 The diagram above is subject to change without notice.
6 6.1 Function manual and operating method of controller Function manual 6.1.1 Temperature parameters ƹ Room set temperatures(Tset) ƹ Room ambient temperatures(Tin-amb) 6.1.2 Fundamental function 6.1.2.1 Cooling mode ƽtemperature setting range is 16-30¨C ƽunder this mode, fan motor of indoor unit operates at setting speed. ƽwhen compressor stops because of malfunction protection, fan motor of indoor unit still operates at setting speed. 6.1.2.
When unit is in HEAT mode, after sleep mode has been set properly, the preset Tset will be increased by 1ć after the sleep program has run for 1 hour, and Tset will be decreased by another 1ć after 2 hours.Tset has been increased by 2ć totally in two hours Then the unit will run at this temperature and at the set speed. In Auto OR fan mode, the setting temp. will not change. 6.1.3.
Controller function of outdoor unit 6.1.1 Parameters of temperature Exhausting gas temperature of outdoor unit(Tex) Ambient temperature of outdoor unit(Tam) 6.1.2 Fundermental function of system In wichever mode, once compressor start-up, it can only be close down 6 minutes later at least(not including malfunction protection/mode switch which requires compressor to stop);Once compressor closes down, it can only restart 3 minutes later at least(including mode switch, stop by remote control etc.
ƽ during heating process, when Tset ćİ(Tin-amb-3) ć İ(Tset +2)ć,the compressor operates in low frequency. during heating process, when (Tin-amb-3) ć˚(Tset +2)ć, then compressor stops running. And outdoor fan motor stops in 60s. Notice: It will take 2 minutes to power-off in 4-way valve when the unit closes down in heating mode or switch from heating mode to other modes. NJIn this mode, there is power supply for reversing valve. Range of temperature setting is 16-30ć. 6.1.2.4.
If there are 6 continuous times of protection, compressor will stop and can not restart by itself and send signal of error to indoor unit. It can only be restart by pressing “ON/OFF” button. In operation if operating time of compressor is over 7 minutes, the number of times will be zero cleared. (2) frequency demultiplying, limitation of current control If current of whole unit is high, frequency of compressor will be demultiplied or limited.
6.1.3.11 The status of indicator in outdoor unit Notice: When the unit is power-on again, the times of all the protection above (including: overloading protection, high exhausting gas temp. protection of compressor, overcurrent protection, module protection etc.) will be reset.
D14 Meaning D15 Meaning blink 6 times Unit closing down for blink 6 times frequency of current 12 A lasting for 2 minutes blink 7 times frequency limiting or demultiplying for rate of min.frequency blink 7 times Unit closing down for PFC protection blink 8 times Unit closing down for frequency variation out of control blink 8 times frequency limiting or demultiplying of compressor compressor overloading current blink 9 times frequency limiting or demultiplying for over temp.

9 Troubleshooting Analysis in this section is used for D.C. Variable Frequency Series. Before analysis, you can diagnose according to the code displayed on indoor unit or indicator display on outdoor unit. (Refer to Malfunction display section).
When unit is cooling or heating, both compressor and outdoor fan don't run When unit is cooling or heating, the compressor runs but outdoor fan doesn't run When cooling or heating, outdoor fan runs, but compressor doesn't run. When cooling or heating, outdoor fan runs, but compressor doesn't run.
Improper setting of temperature Adjust the set temperature Whether cooling (heating) load is proper Check the estimated load of cooling (heating) Poor cooling (heating) effect Malfunction of refrigerant flow Leakage or shortage of refrigerant Vacuumize after leakage detection and leakage repair. Charge refrigerant according to specification.
drain hose is blocked or broken replace the drain hose water leakage connector of refrigerant pipe isn't wrapped well indoor fan collides with other parts abnormal things in indoor unit abnormal shake or sound wrap and tight it again adjust the location of fan remove it compresoor shakes overly adjust the washer and tight the bolt pipes in outdoor unit collides set the pipes apart tighten the connecting bolt metal plates collides stick shake-reduction plaster between the metal plates outdoor fa
9.2 Malfunction display section Analysis or handling of some malfunction display: 1, Compressor discharge protection: Possible reasons: shortage of refrigerant; block of air filter; poor ventilation or air flow short pass in condenser; system has noncondensing gas(ge. Water, air);blockage of capillary (including filter); leakage inside 4-way valve causes incorrect operations; malfunction of compressor; malfunction of protection delay; malfunction of gas discharge sensor; too high outdoor temperature.
7. Module protection : Handling method: Check if the voltage between power module P and N is too low and if the current is too high. In normal condition, voltage between P and N should be about 320V. Abnormal Check power supply circuit of outdoor unit (if PTC resistance rectifying bridge, reactor, capacitance etc. is ok).
