operation
Lowers the operating frequency if the
temperature of the compressor chamber
thermistor (TH1) rises above 105
ϒ
C.
Stops the compressor if the thermistor
stays above 105
ϒ
C for 1 minutes at
minimum frequency or less.
Stops the compressor if the compressor
chamber thermistor is above 114
ϒ
C.
(Or when TH1 shorts)
Lowers the operating frequency if the
temperature of the outdoor heat exchanger
rises above 56
ϒ
C during cooling. Stops the
compressor if the temperature stays above
56
ϒ
C for 1 minute at minumum frequency.
Stops the compressor if an outdoor
thermistor (excluding TH1) shorts.
Stops the compressor if the circuit of an
outdoor thermistor breaks.
Stops the compressor if the operating
frequency is above 70 Hz and the
compressor current is below 1.0 A.
Turns the compressor relay off if the indoor
unit does not receive a serial signal from
the outdoor unit for 8 minutes.
Stops the compressor if the outdoor unit
does not receive a serial signal from the
indoor unit for 30 seconds.
Stop operation
The reason that the fuse operation is by
connection eroor at the inside of terminal
board.
