HPI Inverter Series Control Function 1 General Functions and Operating Rules The HPI SW is parametric. All parameters are shown in Blue color and with Italic style [parameter]. The parameters values are given in the last section of this control logic chapter of the service manual. 1.1 System Operation Concept The control function is divided between indoor and outdoor unit controllers. Indoor unit is the system ‘Master’, requesting the outdoor unit for cooling/heating capacity supply.
HPI Inverter Series Control Function 1.2.3 Compressor Starting Control Frequency Step 3 Step 2 Step 1 1 Minute 1 Minute Time Min 10 Minutes 1.2.4 Minimum On and Off Time 3 minutes. 1.3 Indoor Fan Control 10 Indoor fan speeds are determined for each model. 5 speeds for cool/dry/fan modes and 5 speeds for heat mode. When user sets the indoor fan speed to a fixed speed (Low/ Medium/ High), unit will operate constantly at set speed.
HPI Inverter Series Control Function 1.5 Reversing Valve (RV) Control Reversing valve is on in heat mode. Switching of RV state is done only after compressor is off for over 3 minutes. 1.6 Outdoor Unit Power Supply Relay Control Outdoor unit power control relay is turned to on when unit is turned on by user, and is turned to off 3 minutes after unit is turned to off by user. 1.7 Ioniser Control Ioniser is on when unit is on AND indoor fan is on AND Ioniser power switch (on Ioniser) is on. 1.
HPI Inverter Series Control Function 4.2 Hot Keep Function When starting the unit in heat mode, indoor fan remains off until indoor coil temperature is over 35 degrees. When compressor is stopped, indoor fan speed is reduced to very low speed. 5 Auto Cool/Heat Mode When in auto cool heat mode unit will automatically select between cool and heat mode according to the difference between actual room temperature and user set point temperature (ǻT).
HPI Inverter Series Control Function 7.2 Indoor Coil over Heating Protection ICT Stop-Compresor ICTOH4 HzDown2 ICTOH3 HzDown1 ICTOH2 Stop-Rise ICTOH1 Normal 7.3 Compressor over Heating Protection Compressor temperature can be in one of 5 control zones (4 in protection, and 1 normal), according to the following chart.
HPI Inverter Series Control Function 7.4 Compressor over Current Protection CCR Stop-Compresor CCROC4 HzDown2 CCROC3 HzDown1 CCROC2 Stop-Rise CCROC1 Normal 7.5 Outdoor Coil Deicing Protection 7.5.1 Deicing Starting Conditions Deicing operation will start when either one of the following conditions exist: Condition 1 (Dynamic Deicing): Unit identify temperature drop of 3 degrees compare to steady state values taken 10 minutes after last compressor frequency increasing.
HPI Inverter Series Control Function 7.5.2 Deicing Protection Procedure OCT 12 0 Threshold ON COMP T1 OFF max.
HPI Inverter Series Control Function 9 On Unit Controls and Indicators 9.1 Indoor Unit Controller Controls and Indicators STAND BY INDICATOR OPERATION INDICATOR 1. Lights up when the Air Conditioner is connected to power and ready to receive the R/C commands 1. 2. Lights up during operation. Blinks for 300 msec., to announce that a R/C infrared signal has been received and stored. Blinks continuously during protections (according to the relevant spec section). 3.
HPI Inverter Series Control Function 10 Jumper Settings 10.1 Indoor Unit Controller 0 = Open Jumper (disconnect jumper). 1 = Close Jumper (connect jumper).
HPI Inverter Series Control Function 11 Self Test 11.1 Indoor Unit Controller Self Test To initiate self test, the following steps should be taken: 1. Disconnect All AC power to IDU. 2. Insert Test Jumper on Jumper 9. 3. Apply AC power to IDU. Self test is done in steps. Moving from one step to another is done by pressing mode button. Step number is shown as a binary code display using the OPER, TIMER, STBY, FILTER LED’s, as shown in the following table: Step No. 0 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12.
HPI Inverter Series Control Function Built In Test Stepping Sequence is as following: STEP 0: LEDS TEST x Check all LEDS by observing blinking operation of all LEDS. x Press Mode button once to proceed to step 1. STEP 1: RESET BUTTON TEST AND BUZZER TEST x Press RESET button once. x Buzzer will beep as an indication of RESET button and buzzer operation. x Press Mode button once to proceed to step 2. STEP 2: LOUVER FULL OPEN TEST x Observe louver to make sure that louver is fully open.
HPI Inverter Series x Control Function Press Mode button once to proceed to step 8. STEP 8: RAT SHORT/DISCONNECT TESTS x COOL LED is turned on if RAT is passed, otherwise HEAT LED is turned on to indicate that RAT is short or disconnect. x Press Mode button once to proceed to step 9. STEP 9: ODU POWER SUPPLY TEST x Observe TEST-LAMP connected on the ODU power line. TEST-LAMP will be on as an indication of good supply power to ODU main board. x Press Mode button once to proceed to step 10.
HPI Inverter Series Control Function STEP 15: WATCHDOG TEST x All LEDS blink and IDU will RESET into normal operating mode. STEP 16: REMOTE CONTROL TEST x Press Remote control ON button to turn on Air-conditioner. x Unit will start to operate at the desired mode of operation. Note: Built in test can be aborted any moment if jumper 9 is removed. 11.2 Outdoor Unit Controller Self Test Self Test mode is used to test outdoor unit PCB hardware and connections. Self Test indicators are as the follow: 1.
HPI Inverter Series Control Function 6. Insert Test Jumper on JP2 (PIN5 and PIN6). 7. Apply AC power to ODU. Built In Test Stepping Sequence is as following: STEP 0: SIX-COMPRESSOR CONTROL, RV, CCH, OFAN, and EEV TEST. x All LEDS blinks. x Six compressor control (/UP, /UN, /VP, /VN, /WP, /WN, CCH, RV), RV and CCH are turn on and off sequentially one by one. Use appropriate equipment to test compressor GATING SIGNAL. x Observe outdoor FAN operation at medium speed.
HPI Inverter Series Control Function STEP 4: JP3, TSUCT SHORT/DISCONNECT and COMPRESSOR TURN-OFF. x FAULT LED is turned on STEADY if TSUCT is “PASS”. Otherwise blinks to indicate shorted or disconnected TSUCT sensor (“TSUCT FAIL”). x Verify outdoor FAN operation at Maximum speed. x Verify Compressor Operation at 0Hz (Motor Stop). STEP 5: JP2, HST SHORT/DISCONNECT and OFAN TURN-OFF. x STBY and FAULT LED is turned on STEADY if HST is “PASS”.
HPI Inverter Series Control Function The coding method will be as follow: Heat led will blink 5 times in 5 seconds, and then will be shut off for the next 5 seconds.
HPI Inverter Series Control Function When system enters diagnostics mode (through IDU communication), the last fault code will be displayed even if the system has recover from that fault. The last fault will be deleted from the EEPROM after the system has exit diagnostics mode (through IDU communication). The current system operation mode (cool/ heat/ off) will not be changed when system enters diagnostics.
HPI Inverter Series Control Function 12.5 Going out of Diagnostics Any remote control command received during diagnostics will cause unit to exit diagnostic mode.
