**VM970804C and *MVC800804C combination trim more than 5% settings are invalid. Trimmed up CFM makes miss matching error.
*2 Other than the above, depending on the connected indoor unit, there are restrictions on the positive side Trim setting.
If you want to change the Cool Airow Trim to positive side, be sure to conrm the Airow Trim restrictions in the latest indoor unit installation manual.
The latest manual can be obtained from the website “PartnerLink(InfoFinderPlus/Literature)”.

*3 The Inverter system uses lower compressor speed and lower indoor unit CFM to optimize system performance.
To obtain 100% CFM for home circulation, use full Trim setting instead of Int/Low speed.
This is recommended for applications with unusually cold return temperatures such as basements.
*4 Please refer to the page of “DEHUMIDIFICATION SELECT “ for details of this function.

COMPRESSOR HEAT LOCKOUT 0F to 60F in 5F increments
The compressor will enter a lockout condition and
will not run while the outdoor ambient tenperature is
below the Compressor Heat Lockout temperature.
In this case, the system will use only the backup
heat source.
