Test Operation
3.2.10 Prevention of Micro Heating in Non-operating Unit
In heating operation, this setting is made to prevent room temperature from rising due to micro
heating capacity generated in the unit with its heating thermostat OFF or in the unit with its
heating operation stopped.
•
By switching the BS units to cooling when the system turns OFF the heating thermostat or
stops heating operation, micro heating is prevented.
•
By enabling the micro heating prevention setting of the outdoor unit, prevention of micro
heating of all BS units connected to the outdoor unit is enabled. (Default setting of BS unit)
•
Setting by BS unit is enabled by changing the micro heating prevention setting of every BS
unit. (In this case, enable the outdoor unit setting.)
3.2.11 Reduction of Cooling/Heating Selection Time of BS Units
Make this setting to reduce selection time between cooling and heating of the BS units, with
careful attention paid to the following points.
•
This setting is only enabled in case the refrigerant piping length between every BS unit
connected to the outdoor unit and the indoor unit is not more than 10 m. (Refer to the figure
shown below: (a)
≤
10 m and (b)+(c)
≤
10 m and
…
)
•
In case the refrigerant piping length between the BS units and the indoor units is long,
refrigerant passing sounds may become louder when the BS unit selects operation mode
between cooling and heating.
•
This setting reduces the operation mode selection time in all the BS units within the same
refrigerant circuit.
