Output Frequencies - AUX ASW-H09A4/SAR1DI Service Manual

4、output frequencies: F = Fo + ΔF
ΔF =Kp×（En+1- En）+ Ki×En+1 + Kd×（En+1 - 2En + En-1）
Fo=20， Kp=6.0, Ki=8.0, Kd=2.0 (EEEPROM can adjust)
a .Frequency range: 20Hz～85Hz,if F＜20Hz， 20Hz is the bottom；if F＞85Hz，85 Hz is the
top.
b. En+1=Tr-Ts，En+1 range: -3 ～+13
c. If consecutive time of En+1≤-2 is 2min,the compressor will be shut down.
d. Starting with power, if En+1≤0,the compressor won't work, if En+1＞0,the compressor will
open.
e. There are no temperature compensation for the firstly open, when the compressor start, it
will be Tr temperature compensation, for example, compensate with 2℃, the Tr=Tr （true） +2℃.
f. when the compressor shut down, the indoor fan will still running according to the setting
wind.
The above is the work frequency without any other restrictions on high-frequency and
protections on down-frequency; if there are restrictions and protections, the frequency vale
will adjust on the above value, and the adjust value according to the certain mode and the
fault protection instructions.
5、In cooling mode, it can set as automatic wind, high wind, medium wind, low wind to meet
requirement, and the automatic wind speed can controlled as follows：
when Tr≥Ts+3℃,High wind
when Ts+1℃≤Tr<Ts+3℃,Medium wind
when Tr＜Ts+1℃,low wind
At automatic speed, when the wind speed from low switching high, the wind speed without
delay; while from high switching low, there will be delay with 3 min.
6、The functions of this model are as follows: time setting, sleep, auto start, Anion, high
efficiency
7、According to cooling operation, there are anti-freeze protection of indoor coil , temperature
thermal protection of outdoor exhaust, over-current protection, overheating protection of
compressor, fault protection of indoor fan , sensor fault protection, fault protection of module,
fault protection of communication, 3min delay protection of compressor.
8、First start with power without 3 min delay protection.
9、The order of on/off of Outdoor fan and compressor: The compressor will open 5s later after
outdoor fan open and the outdoor fan will shut down 15s later after the compressor shut down.
10、The restrictions and protection for Ta when cooling.
When Ta≥47℃,it open as cooling mode normal, the maximum work frequency of
23
