DAIKIN MULTI-SPLIT
Up to four rooms on one outdoor unit
The Daikin 4MXM80A9 is a multi-split outdoor unit for up to four indoor units, for a three- or four-bedroom home, or bedrooms plus a living area.
One outdoor unit replaces four separate condensers, which saves outside wall space and keeps the side of the house tidier and quieter.
It runs on R32 and is rated up to A+++ in cooling and A++ in heating, depending on the indoor units connected.
INDOOR UNITS
Choose an indoor unit for each room
Each room gets its own Perfera wall unit, sized to that room: the FTXM25A or FTXM35A for bedrooms, the FTXM50A, FTXM60A or FTXM71A for living areas.
Mix sizes to suit the house: smaller units in the bedrooms, a larger one in the living room. We check the combination against Daikin’s tables before you order, because the indoor units together have to suit the outdoor unit.
Every indoor unit has its own controls and built-in Wi-Fi, so rooms are switched on and set separately. All units on one outdoor unit run in the same mode: one room cannot heat while another cools.
MADE FOR SOUTH AFRICAN POWER
One condenser outside, Daikin South Africa stock
One outdoor unit instead of one per room means less wall space taken up outside, fewer units to hide, and less outdoor noise than several condensers running together.
This unit is supplied through Daikin South Africa for a 220–240 V single-phase supply, so the local Daikin warranty applies and parts come through Daikin’s South African network. Auto-restart brings the system back to its previous settings when the power returns after load-shedding.
A multi-split system has to be designed and installed by a qualified installer. Our installers cover the major South African cities and quote separately; send us the room sizes and we will match the indoor units to the outdoor unit.

Figures from Daikin’s published data for the 4MXM80A9. Capacity in use depends on the indoor units connected and how many run at once.
How the 4MXM80A9 sits against the alternatives
For three rooms the 3MXM68A9 is enough; for five, the 5MXM90A9.
If the rooms are far apart, separate single splits can be simpler and give each room its own full output.
