Field Settings for Outdoor Unit
 m2-39: Emergency operation "Slave 1". To disable permanent compressor operation of
 m2-40: Emergency operation "Slave 2". To disable permanent compressor operation of
Combination table setting 2-38, 2-39 and 2-40:
 m2-51: Master/Slave setting Multi. When 2 or 3 modules are installed as a multi-outdoor
 m2-81: Cooling comfort setting. The comfort level is related to the timing and the effort

"Slave 1" unit of a multi outdoor system:
 Default value: 0. Compressor operation enabled.
 Field set:
 Set 1: Inverter 1 compressor is disabled.
 Set 2: Inverter 2 compressor is disabled. Only to make in case of 16-20 HP. Note that
compressor 2 is left side located.
 Set 3: All compressors in this master module are disabled permanent.
"Slave 2" unit of a multi outdoor system:
 Default value: 0. Compressor operation enabled.
 Field setting:
 Set 1: Inverter 1 compressor is disabled.
 Set 2: Inverter 2 compressor is disabled. Only to make in case of 16-20 HP. Note that
compressor 2 is left side located.
 Set 3: All compressors in this master module are disabled permanent.

(by common refrigerant piping and wiring by terminals Q1Q2) configuration is automatically
detected. In certain cases, the sequence of the slave units need to be set manually (in case
of AIRNET monitoring).
 Default value: 0. Automatic detection.
 Field setting: ensure that the modules in a multi are set different status. Even some
modules in a multi are set manually to same status, U7 error will appear.
 1: Forced Master (F1F2/Ind terminals should be connected to indoor units).
 2: Forced Slave 1 (only Q1Q2 terminals should be wired to Master module).
 3: Forced Slave 2 (only Q1Q2 terminals should be wired to Master module).
(power consumption) which is put in achieving a certain room temperature by changing
temporally the refrigerant temperature to different values in order to achieve requested
conditions more quickly.
 Default value: 1 (Mild). Undershoot during cooling operation is allowed compared to the
requested refrigerant temperature, in order to achieve the required room temperature
very fast. The undershoot is not allowed from the startup moment. The startup occurs
under the condition which is defined by the operation mode. In case of cooling operation
the evaporating temperature is allowed to go down to 6°C on temporary base depending
on the situation. When the request from the indoor units becomes more moderate, the
system will eventually go to the steady state condition which is defined by the operation
method above. The startup condition is different from the powerful and quick comfort
setting.
 Field setting:
 0: Eco. The original refrigerant temperature target, which is defined by the Te setting
(field setting 2-8) in cooling mode, is kept without any correction, unless for protection
control.
