Indoor heating test run demand

The heating test run is performed. (→ Note 1)

Fan motor forced operation Drive the fan motor forcedly.

When pushing SW801 again or when 2 minutes elapsed, the operation returns to the normal control.

(No operation especially)

PMV full open operation

Open PMV (Pulse Motor Valve) fully.

When pushing SW801 again or when 2 minutes elapsed, the operation returns to the normal control.

PMV full close operation

Close PMV (Pulse Motor Valve) fully.

When pushing SW801 again or when 2 minutes elapsed, the operation returns to the normal control.

PMV middle opening operation

Set PMV (Pulse Motor Valve) to middle opening (250 pulses).

When pushing SW801 again or when 2 minutes elapsed, the operation returns to the normal control.

[NOTE]

Although these operations can be performed even during operation, basically perform operation while the unit stops.

If performing this operation during driving the unit, it is dangerous because the pressure may change suddenly.

Note 1) Indoor cooling test run demand / Indoor heating test run demand

Only when combining with the following indoor unit, cooling/heating operation can be performed from the outdoor unit.

Test run is available: Indoor unit of 4 series and after (RAV-SM∗∗∗4UT-E etc.)

Test run is unavailable: Indoor units other than the above-mentioned indoor units, or indoor units other than above-mentioned indoor units are included in the twin connection.

Note 2) The forced test run by this setting cannot be cleared on the indoor remote controller. Be sure to clear the test run by operation of the outdoor unit. (Push SW801 again for 1 second.)
