will be shielded.
2) When the follow-me function is available, the PCB will not respond according to the setting temperature
from follow-me signal every 3 minutes.
3) The PCB will take action to the mode change information from remote controller signal, and the
follow-me function will be turned off. (if the wired remote controller does not initiate follow me function).
4) When the unit is running with follow-
me function, if the PCB doesn’t receive any signal from
remote
controller for 7 minutes or pressing FOLLOW ME button again, the follow-me function will be turned off
automatically, and the temperature collection function of room temperature sensor will be available, the
PCB will control the unit according to the room temperature detected from its own room temperature
sensor and setting temperature.
5) When the indoor PCB receives the follow-me signal from wired remote controller, the control is the
same as that from wireless remote controller, but buzzer will not respond. When the PCB receives
turning-off follow-me signal from wired remote controller, the unit will quit follow-me function at once.
The follow-me function controlled by wired remote controller prevails that by wireless remote controller.
1.3.11 Point Check Function (Excluding 12K)
There is a check switch in outdoor PCB.
Press the switch SW1 to check the states of unit when the unit is running.
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 procedure 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 digit
al 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 outlet temp.(heating T2
，
cooling T2B)
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: “――” 07 Condenser pipe temp.(T3)
08 Outdoor ambient temp.(T4)
09 Compressor discharge temp.(T5)
The display value is between 0~129 degree.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)
