Air Flow Adjustment
To improve the effects of cooling and heating, use the outlet louver appropriately for cooling and
!
heating operations. When in cooling operation the most efficient louver position will be horizontal,
and when in heating operation the optimum louver position is downwards.
The MM-S, MM-SR unit is different due to its installation position, in this case the above louver
!
positions should be reversed.
Increasing Heating Effect
One method to increase the heating effect is to fit an additional means of re-circulating the
!
warmed air from the upper part of the room;
However if the heating effect of the air conditioner is not good owing to the installation position or
the structure of the room, then reset the room temperature regulator as follows to raise the
!
temperature of the room. Adjust positions 1 and 2 on DIP switch SW03 located on the Indoor
PCB (MCC-1361-01), according to the table below:
Dip Switch SW03
Positions 1 & 2

The Modular Multi Indoor Units have a de-rating option that can be implemented to closely match
actual load requirements.
To de-rate any Toshiba MMS Indoor Unit, adjust Dip Switch SW08 located on the Indoor Unit PCB
(MCC-1361-01) in accordance with the chart below.
The de-rating options available for the Toshiba MMS Indoor Units are as follows:
