1. Application Range
This function guide can be used for the HSU-09HS03/R2(DB) air-conditioners and
other frequency-convertings made by Headquarters of Qingdao Haier
Air-conditioner Co.,Ltd
Indexes in this guide (symblised by parameters) refer to the indexes stored in the
EEPROM. Please refer to the EEPROM index chart.
2. Temperature Ajusting function
. This function will decide the outdoor-set’s running speed according to the
domestic temperature and the set temperature.
. Control the domestic blower fan according to the need for temperature adjusting
when the wind rate is automatic
. Control the domestic blower fan according to the disc-tube temperature when it’s
running for heating.
2.1.1 Indoor environment temperature sensor specification
Under the conditions of short circuit or open circuit, the indicative light will flash an alarm and
the indoor blower fan stops. When it returns to normal condtions, the operation will come
back to normal.
Short circuit
Temperature: over 126 . Sixteen scales: over F8H. Resistance value: below 0.65 K.
Voltage: over 4.85 V
Normal temperature
Temperature: 25 . Sixteen scale: 40H Resistance value: 23K . Voltage: 2.33 V
Disconnection
Temperature : below minus 31 . Sixteen scale: below 08H . Resistance value:
below 620K. Voltage: below 0.15 V
.B index=4200 R(25 )=23K
2.1.2 During the time when the heat running starts and indoor blower fan stops or
when the warm boot starts and within 30 seconds after the indoor blower fan starts,
the resistance value for indoor environment temperature sensor will be neglected.
2.2 The frequency kept when the frequency rises.
. When the operation enters into the work mode, in order to insure the full
oil-returning, some frequency should be kept for some time.

When the unit is switched on and the forcible running is over, the temperature level
control starts.
2.3 Modify the set temperature
The set temperature can be modified according to the unit’s operation mode, wind
volume or whether it is under forceful running condition.
The modification of wind volume is only limited within the switch between weak
