Description

Mode No.

Silent Operation

16(26)

Low noise start & stop time

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.
