5.2.3. Remote controller
5.2.3.1. Quiet (Low Noise) Operation
Lower the operation sound of the outdoor unit.
Silent Operation can be activated by:
1. Automatic control (by field setting from remote controller)
2. External activation (from optional PCB KRP58M)
Quiet (Low Noise) Operation by Automatic Control
Silent operation can be set by field setting from the wired remote controller:
When 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.
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.
External Activation from Optional PCB
Quiet (low noise) operation can also be activated from the optional PCB.
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 KRP58M enables the use of an external time clock.
Same 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 KRP58M.
The Quiet (low noise) operation will be overruled in the following conditions:
• Pump down residual operation
• Startup control
• Defrost operation
• Oil recovery
