Point Check Function
There is a check switch in outdoor PCB.
Push the switch SW1 to check the states of unit when the unit is running. The digital display tube will display
the follow procedure when push SW1 each time.

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)
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".
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: "――"
The display value is between 30~120 degree. If the temp. is
lower than 30 degree, the digital display tube will show "30".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)
The display value is hex number.
Off:0, Fan only 1,Cooling:2, Heating:3, Forced cooling:4
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.)

Remark
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.
