Minimum heat (All) operation
While this function is selected, all indoor units start the minimum heat operation when all the in-
door units are stopped by operation of the [On/Off button].
• When the room temperature is higher than 50 °F (10 °C), MIN. HEAT operation dose not start.
Operation starts and maintains the room temperature at 50 °F (10 °C) when the temperature
drops below 50 °F (10 °C).
• When "MIN, HEAT" operation stops, the room set temperature quickly returns to the preset
temperature.
Economy (All) operation
• If all the indoor and outdoor units are changed to economy mode, this can save more energy
than setting of each indoor unit individually.
• Economy operation is energy saving, as the set temperature of indoor unit is shifted by 2 °F
(1 °C) and the maximum electric value of the outdoor unit is suppressed.
Example: Cooling operation
