<Auto vane drive>
(a) The vane is driven by DC12V motor.
(b) Air discharge direction is selected depends on the number of pulse were sended.
(c) Before start driving the auto vane, detect the standard position first, output the number of pulse to each air discharge.
(d) The speed of the auto vane drive for both open and close are setted at 200 pulse/sec.
(e) Method of driving the auto vane.
1
Detecting the standard position:
Output 1600 pulse to the opening direction.
2
Position setting:Output the number of pulse indicated no below chart to the closing direction.
(4) Detecting abnormalities in the outdoor unit
After the compressor has been continuously operated for 3 minutes, if the difference between the indoor coil temperature
and room temperature is out of RANGE C for 1 minute, the indoor fan speed will turn to LOW. Five minutes later, if the dif-
ference is still out of
RANGE C,the outdoor unit is functioning abnormally. Thus, the compressor stops and check code “P8” appears on remote
controler.
RANGE A : Indoor coil temperature is more than 9 degrees above room temperature.
RANGE B : Indoor coil temperature is within 5 degrees either way of room temperature.
RANGE C : Indoor coil temperature is more than 9 degrees below room tempetature.
