Airow Trim Oset
*1, *2
0: 0% 1: +2.5% Used for additional trim setting by adding
2.5% to basic airow trim setting. This
setting aects all trim settings except
+15% High (cooling or heating).
NOTE: Parameters as per factory setting are highlighted in bold and underlined.
*1 *VZC200601* with **VC960804C, **VM970804C and *MVC800804C combination trim more than 5% settings are invalid.
Trimmed up CFM makes miss matching error.
*2 Depending on the connected indoor unit, there are restrictions on the posive side Trim setting.
If you want to change the Cool Airflow Trim to positive side, be sure to confirm the Airflow Trim restrictions in the latest indoor unit installaon
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 opmize system performance.
*4 Please refer to the page of "D
EHUMIDIFICATION SELECT" for details of this funcon.
To obtain 100% CFM for home circulaon, use full Trim seng instead of Int/Low speed.
This is recommended for applicaons with unusually cold return temperatures such as basements.
NOTE:
The specification of *VZC200241AF, 0361AE, 0481AE and 0601AE or earlier models are different from this
specification. For details, see the Installation Manual or Service Manual that matches the Major and Minor revision of
model name.
