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

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.

、 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.

、
The functions of this model are as follows: time setting, sleep, auto start, Anion, high
efficiency

、
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.

、
First start with power without 3 min delay protection.

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.

、 The restrictions and protection for Ta when cooling.
When Ta ≥ 47 ℃ ,it open as cooling mode normal, the maximum work frequency of
