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 IGBT radiator temp. is
105 degree. the digital display tube show "1.6",it means the
IGBT radiator temp. is 116 degree)
The indoor unit can communicate with outdoor unit well.
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 capacity demand is 0, , the
digital display tube will show "0. If the indoor unit is not
connected, the digital display tube will show: "――"(heating

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 indoor unit is not connected, the digital
display tube will show: "――"
