4.Because this control automatically switches the operation mode, if the air
conditioner is not a cooling / heating free unit, always register indoor units which have
the right to select cooling or heating for the same cooling system to the same
automatic cooling / heating switch group, when controlling indoor units which do not
have such rights.
Unexpected things may happen if control is done using the following
incorrect automatic cooling / heating switch group settings.
If indoor units (address 1-02) which do not have the right to select cooling or heating
for the same cooling system are not registered to the same automatic cooling /
heating switch group, address 1-02 will behave in the following way.
[Actions related to operation mode]
If the room temperature of Group 1 rises, group 1 will switch to cooling as per this
control and the set temperature will become 25°C (if the temperature difference is
5°C).
When this happens, the set temperature of the indoor unit at 1-02 will continue at
23°C although only the operation mode will change to cooling, i.e. in a different
operation mode from the other indoor units in Group 2.
→The operation mode will be determined by Group 1.
[Actions regarding set temperature]
If the room temperature of Group 2 rises, group 2 will switch to cooling as per this
control and the set temperature will become 28°C (if the temperature difference is
5°C).
When this happens, the operation mode of the indoor unit at 1-02 will continue in
heating and only the set temperature will change to 28°C, i.e. in a different operation
mode from the other indoor units in Group 2.
→The set temperature will be determined by Group 2.
