(2) Heating
Room temperature control is obtained by cycling the compressor ON and OFF under control of the room
temperature sensor in the remote control unit.
The room temperature (and other information) is transmitted every 5 minutes by the remote control unit to the
controller in the indoor unit.
Once the compressor starts, it keeps running for 5 minutes.
Once the compressor stops, it will not start running again for 5 minutes.
Thermo. ON : When room temperature falls 1 C below the set temperature T C,
the compressor turns ON.
Thermo. OFF : When the room temperature rises above the set temperature T C,
the compressor turns OFF.
NOTE
The temperature described in this page and previous page gives you an example with remote
control operation. In case of the operation controled by an indoor air temperature sensor, operation
temperature differ somewhat.
