Appendix 203
2. Setting of CONTROL MODE selector switch (RS1)
To use the system only for display function only in individual display mode
To operate the system using constant input to the input A
Caution The input B is used for forcedly OFF. If this input B is turned ON, the system will be put into
“Stop + Remote controller inhibited”, thus disregarding the input A. Even if the input A is turned
ON with the input B in an OFF state, the content with the input A turned ON will not be provided.
In this case, the input A should be turned ON again.
To operate the system using instantaneous input to the input A
(Use instantaneous input with ON time of 200 msec or more for the input A.)
To conduct demand control using input B
Forcedly thermostat OFF command
This command is used to operate the indoor unit only in forcedly fan mode.
Energy saving operation command (*)
This command is used to operate the system with set temperature increased by 2°C in
cooling operation or decreased by 2°C in heating operation.
Caution
In this case, even though the input A is turned ON, the system will make a stop, thus
stopping all units in one and the same group.
* On the SkyAir series, even though Position D or F is selected, the forcedly thermostat OFF
command will be issued.
