Indoor unit fan operation inhibit setting during refrigerant recovery
• When service mode 2-20 is set to use set 2 or set 3, this unit will recover the refrigerant inside the air-
conditioner indoor unit at regular intervals in order to, for example, cool a showcase even when the
heating cycle is OFF such as during the night. During this time, the fan in the air-conditioner indoor unit
is usually allowed to run to keep the compressor on the showcase side running. If the air from the fan
affects the security system, or results in a noticeable amount of warm air during night hours or other
time periods, the fan can be turned OFF by enabling this switch. (If this switch is enabled, the
compressor on the refrigeration equipment will stop for about 3 minutes.)
(
∗
) In heating mode, after operation is stopped from the remote controller for 20 consecutive minutes, four way valve A switches. (The
remote controller display continues to indicate heating mode.)
(Note, this mode only operates in the residual refrigerant recovery 3 cycle and when service mode 2-20 is set to use set 2 or set 3.)
