Remark
If the temperature is lower than 0 °C, the digital display shows "0."
If the temperature is higher than 50 °C, the digital display shows "50."
If the indoor unit is not connected, the digital display shows: "
If the temperature is lower than -9 °C, the digital display shows "-9."
If the temperature is higher than 70 °C, the digital display shows "70."
If the indoor unit is not connected, the digital display shows: "
The display value is between 30–129 °C.
If the temperature is lower than 30 °C, the digital display shows "30."
example, if the digital display shows "0.5",
the compressor discharge temperature is 105 °C.
The display value is a hex number. For example, the digital
display tube shows "Cd", it means AD value is 205.
The display value is a hex number. For example, the digital
display tube shows "Cd", it means AD value is 205.

The display value is a
hexidecimal number. For
example, the digital display
show 2A, then Bit5=1,
Bit3=1, and Bit1=1. This
means that
a frequency limit may be
caused by T4, T3, or the
current.
