报警说明

 

A0: 

报警和风机温差

 

 

表示用来激活高温报警报警的温差(

 AH

 )

。出

现一个报警时(如图中所示),“

A0

”的值决定

了温度报警的实际触发温度。“

A0

”的值(负值

或正值)决定了“

AH

 

报警的属性(分别为绝

对或相对),具体说明如下

  A0

 0 

AH

 

表示绝对

 

  A0> 0 

AH

 

表示相对设定点

说明

 

AH 

设定:

10

度是出厂设定(

-50

99

是上限和下限)

原厂设定,就是

ST

设定(

35

度),

AO

设定(

度)

 

AH

设定(

10

度)

  

例如:如果机柜内部温度是

46

度(

ST

设定)

35+  

AH

设定)

10=45

度,这个时候空调显示温度是

46

度,大于

45

度,这时空调会报警

部温度大于

45

度就会报警

10-

AO

设定)

2=43

度,这时空调显示

温度是
