2.9 Quiet (Low Noise) OperationPurpose

Lower the operation sound of the outdoor unit.

SettingSilent Operation can be activated by:1. Automatic control (By field setting from remote controller)2. External activation (from optional PCB KRP58M1)

2.9.1 Quiet (Low Noise) Operation by Automatic ControlTable

Silent operation can be set by field setting from the wired remote controller:

: Factory setting

MethodWhen setting mode 16(26)-0-02, quiet (low noise) operation will be carried out by presuming the current time in accordance with the outside temperature. Automatic mode will start when the outdoor temperature is = average max of last 10 days -5°C and will be conducted for 10 hours.The maximum outdoor temperature is supposed to occur at 14:00h. As the time judgement is made in accordance with the outdoor temperature, the above mentioned timing is an estimation only.

Capacity priority settingWhen setting mode 16(26)-0-04, the low noise operation will be stopped when the heating or cooling load increases. In that case, the operation will return to normal operation. The unit will return to low-noise operation when the heating or cooling load decreases again.

2.9.2 External Activation from Optional PCBGraph

Quiet (low noise) operation can also be activated from the optional PCB. (KRP58M1)

Quiet (low noise) operation will start when the contact on LNOP-COM is closed and will remain active as long as the contact is closed. No field setting on the outdoor unit or by remote controller is required. Quiet (low noise) operation will be ended when the contact is re-opened. Use of the KRP58M1 enables the use of an external time clock.

Capacity priority SettingSame as with the automatic control, priority for capacity can be set. Priority for capacity will be activated by changing field setting 26-0-03 in combination with the closed contact on KRP58M1.

Explanation If several wireless remote controller units are used together in the same room (including the case where both group control and individual remote controller control are used together), be sure to set the addresses for the receiver and wireless remote controller. (For group control, see the attached installation manual for the indoor unit.) If using together with a wired remote controller, you have to change the main/sub setting or the receiver.

Setting the Receiver

Through the small opening on the back of the receiver, set the wireless address switch (SS2) on the printed circuit board according to the table below.

When using both a wired and a wireless remote controller for 1 indoor unit, the wired controller should be set to MAIN. Therefore, set the MAIN/SUB switch (SS1) of the receiver to SUB.

2.13 Outdoor Unit Low Noise Operation

Purpose Lower the operation sound of the outdoor unit.

Setting Outdoor unit low noise operation can be activated by:1. Automatic control (By field setting from remote controller)2. External activation (from optional PC board KRP58M)

2.13.1 Outdoor Unit Low Noise Operation by Automatic control

Table Outdoor unit low noise operation can be set by field setting from the wired remote controller:

Method When setting mode 16(26)-0-02, outdoor unit low noise operation will be carried out by presuming the current time in accordance with the outside temperature. Every 5 minutes, the outdoor unit will check the actual outdoor temperature. The unit will keep in it's memory an average of the highest temperature of the last 10 days. Automatic mode will start when the outdoor temperature is = average max of last 10 days -5°C and will be conducted for 10 hours.The maximum outdoor temperature is supposed to occur at 14:00h. The night time low noise operation is supposed to be activated between 22:00h and 08:00h in factory setting, but can be changed by field setting.As the time judgement is made in accordance with the outdoor temperature, the above mentioned timing is an estimation only.

Capacity Priority Setting

When setting mode 16(26)-0-04, the low noise operation will be stopped when the heating or cooling load increases. In that case, the operation will return to normal operation. The unit will return to low-noise operation when the heating or cooling load decreases again.

2.15 Setting for Simplified Server Room Application

Support for Simplified Server Rooms

Used in machine rooms (server rooms) requiring no dehumidification.This function expands the range of compressor operation under minimum-load conditions through sensible heat disposal and keeps ON/OFF operations to a minimum between mid and winter seasons, thus enhancing the efficiency of compressor operation.For performance characteristics (in cooling operation) with this function set, refer to information in table below.Cooling Capacity Characteristics (with support for simplified server rooms set)

* The max. cooling capacity coefficient represents maximum cooling capacities under each temperature condition, when assuming the coefficient under the JIS standard condition as 1.

Notes: 1. Do not attempt to use this function for full-scale server rooms such as unmanned base stations or else.

2. Be sure to make setting of indoor unit remote controller to a fixed setting of Cooling and Sharp (or High) airflow rate. (Do not make setting of this remote controller to Automatic mode.)

3. The operational temperature range is the same as that in normal mode. Outdoor suction air temperature: –15°C to 50°CDB Indoor suction air temperature: 14°C to 25°CWB

方法 设定模式16(26)-0-02时，将根据室外温度推测当前时间，从而执行夜间低噪

音运转。 当室外温度 = 最近10天的平均最高温度 - 5℃时，将起动自动模式并持续运转10小时。假设最高室外温度出现在14:00h。 由于根据室外温度来判断时间，因此上述时间仅为估计值。

能力优先设定 设定模式16(26)-0-04时，低噪音运转将在制暖或制冷负载增加时停止。 在这

种情况下，将返回正常运转模式。 当制暖或制冷负载再次减少时，机器将返回低噪音运转模式。

2.11.2 从选配的印刷电路板进行外部启动

图 也可从选配的印刷电路板启动夜间低噪音运转。（KRP58M51）

当LNOP-COM 上的触点闭合时，夜间低噪音运转开始，且只要触点保持闭合，

此运转

将一直有效。 此时不需要在室外机上或通过遥控器进行现场设定。

当触点重新断开时，夜间低噪音运转停止。

使用KRP58M51 可启用外部时钟功能。

能力优先设定 与自动控制一样，可对能力优先进行设定。 通过结合KRP58M51 上的闭合触点来更改现场

2.13 应用于低湿度场合的设定2.13.1 RZQ125KMY3C

目的 当使用RZQ空调机在计算机室(EDP室)、技术室等低湿度应用场合进行常年制冷运转时，

可进行该设定，以提高空调机的能力。

低湿度区域

的定义

注意 如果在“低湿度区域”以外的范围使用“低湿度设定”，将会增加室内机盘管积冰或室

压缩机控制 压缩机频率的控制取决于目标蒸发温度。而目标蒸发温度的控制则取决于制冷负载。

最低目标 Te = 2 ℃ 最低目标 Te = 0 ℃ 初始最低目标Te= 2℃，但可根据实际的 Te 值进行更改，以避免启动冻结运转：Te累计20分钟≤-1℃ =>将目标 Te 改为≥ 5℃Te累计30分钟≤-1℃ =>将目标 Te 改为≥ 8℃
