1. Fresh Air Intake

Air recycled indefinitely can become stale and stagnant with air quality suffering significantly. Fresh air is the answer and it is for this reason that the PMFY- series takes in air directly from outdoors. This fresh air intake allows you to enjoy the comfort of crisp, refreshing air in the confines of your living or working space.

2. Light and Compact

The main unit weighs only 31 lb. and the panel merely 7 lb. This makes the PMFY - series one of the lightest in the industry. The unit size is also quite small, having been standardised to a strikingly compact 33-5/8 inch. All of this make the chore of installation and maintenance that much simpler and easier.

“Timer is Off” indicator

Indicates that the timer is off.

Temperature Setting

Shows the target temperature.

Day-of-Week

Shows the current day of the week.

Time/Timer Display

Shows the current time, unless the simple or Auto Off timer is set. If the simple or Auto Off timer is set, the time to be switched off is shown.

“Sensor” indication

Displayed when the remote controller sensor is used.

“Locked” indicator

Indicates that remote controller buttons have been locked.

“Clean The Filter” indicator

To be displayed on when it is time to clean the filter.

Timer indicators

The indicator comes on if the corresponding timer is set.

Up/Down Air Direction indicator

Shows the direction of the outcoming airflow.

“One Hour Only” indicator

Room Temperature display

Shows the room temperature. The room temperature display range is 46~102°F. The display blinks if the temperature is less than

PMFY-P·NBMU-E series are capable of taking air from outside. When taking air from outside, the duct fan is used. The air capacity should be 20% or less of the airflow SPEC(Hi).

Operation in conjunction with duct fan (Booster fan)

●Whenever the indoor unit is operating, the duct fan operates. (1)Connect the optional multiple remote controller

adaptor (PAC-SA88HA-E) to the connector CN51 on the indoor controller board.

(2)Drive the relay after connecting the 12V DC relay

between the Yellow and Orange connector lines.

(w)Use a relay of 1W or smaller. MB: Electromagnetic switch power relay for duct fan.
