Electrical Control Function
Press the switch N times it will display the content corresponding to No. N. After getting into the check
function, it will display No. N with 1.5s, meanwhile the low bit decimal of digit display flashing, indicated to
get into the check function display. After 1.5s, it will display the content corresponding to No. N.
the digital display tube will display the follow
ing
when push SW1 each time.
N Display Remark
00 Normal display Display running frequency, running state or malfunction code
01 Indoor unit capacity demand code
Actual data*HP*10
If capacity demand code is higher than 99, the digital display
tube will show single digit and tens digit. (For example, the
digital display tube show “5.0”,it means the capacity demand
is 15. the digital display tube show “60”,it means the capacity
demand is 6.0)
02 Amendatory capacity demand code
03
The frequency after the capacity requirement
transfer
04 The frequency after the frequency limit
05 The frequency of sending to 341
06 Indoor unit evaporator temp.(T2)
If the temp. is lower than 0 degree, the digital display tube will
show “0”.If the temp. is higher than 70 degree, the digital
display tube will show “70”.
07 Condenser pipe temp.(T3)
If the temp. is lower than -9 degree, the digital display tube will
show “-9”.If the temp. is higher than 70 degree, the digital
display tube will show “70”. If the indoor unit is not connected,
the digital display tube will show: “
―― ”
08 Outdoor ambient temp.(T4)
09 Compressor discharge temp.(Tp)
The display value is between 13~120 degree. If the temp. is
lower than 13 degree, the digital display tube will show “13”.If
the temp. is higher than 99 degree, the digital display tube will
show single digit and tens digit. (For example, the digital
display tube show “0.5”,it means the compressor discharge
temp. is 105 degree. the digital display tube show “1.6”,it
means the compressor discharge temp. is 116 degree)
For
KV48ODU-ARF21B
&
KV60ODU-CRF21
The
display
value
is between 13~129 degree. If the temp. is
lower
than 13
degree, the digital display tube will show “13”.
10 AD value of current
The display value is hex number.
11 AD value of voltage
12 Indoor unit running mode code
Off:0, Fan only 1,Cooling:2, Heating:3, Forced cooling:4
For
KV48ODU-ARF21B & KV60ODU-CRF21
, Off:0, Fan
only
1,Cooling:2, Heating:3
13 Outdoor unit running mode code Off:0, Fan only 1,Cooling:2, Heating:3, Forced cooling:4
14 EXV open angle
Actual data/4.
If the value is higher than 99, the digital display tube will show
single digit and tens digit.
For example ,the digital display tube show “2.0”,it means the
EXV open angle is 120×4=480p.)
15 Frequency limit symbol
Bit7
Frequency limit
caused by IGBT
radiator
The display value is hex
number. For example,
the digital display tube
show 2A,then Bit5=1,
Bit3=1, Bit1=1.
It means frequency limit
caused by T4,T3 and
current.
Bit6
Frequency limit
caused by PFC
Bit5
Frequency limit
caused by T4.
Bit4
Frequency limit
caused by T2.
Bit3
Frequency limit
caused by T3.
