Description
To climatize a room with a wall-mounted split: 2,924 frigories/h (3.4 kW) nominal cooling capacity. TCL S12F5S3 includes an indoor and an outdoor unit; it is not a system for distributing cold independently between multiple rooms. Check the load of the room and the installation space before choosing. Installation sold separately.
The choice of power depends on the space, its orientation, and its insulation. A split unit located in one room does not guarantee the same temperature in adjacent rooms; to serve multiple rooms, it is advisable to consider a multisplit system or a ducted installation.
Wi-Fi is included to manage the equipment from the manufacturer's compatible application.
What does TCL S12F5S3 include?
A split set 1×1: one indoor unit connected to one outdoor unit.

What to check before installing TCL S12F5S3
The choice of equipment does not replace the inspection of the installation by a qualified professional.
- Check the gaps: interior 778 × 272 × 192 mm; exterior 712 × 459 × 276 mm. Add the ventilation and service clearances indicated in the manual.
- 1/4″ / 3/8″ pipe. Pre-charge for 5 m; maximum run 25 m and maximum height difference 10 m. Add 15 g/m of R32 for each meter that exceeds 5 m, according to the technical sheet of this reference. Verification and adjustment by a qualified installer.
- Evaluate orientation, insulation, and use of the room; the cooling capacity does not replace the calculation of thermal load. Request separately installation, materials, and commissioning.

Load calculation and documentation
Outdoor unit: ST12F3. Check PCB and inspection.
Additional load: 15 × (L − 5) g, only when L exceeds 5 m and does not exceed 25 m of travel.
L is the one-way length between interior and exterior, not the sum of both pipes. Outer diameters of refrigerant piping in liquid / gas order.
Check the PCB, review, and manual. Installation and handling of refrigerant by a qualified professional; do not add gas only due to lack of cooling.

Questions about TCL S12F5S3
Would you choose it for a very hot attic?
For an attic that overheats, I would first check the square meters and the insulation of the ceiling. This unit has about 2,924 frigories/h. The next one in this range, TCL S18F5S3, it rises to about 4.420: it's a considerable jump. We help you check if you need it before recommending a larger one.
What changes compared to the TCL S09F5S3?
This one has more cooling power: it is around 3,000 frigories, compared to the 2,250 of the smaller one. If your room is small, well insulated, and does not overheat, compare the TCL S09F5S3 before purchasing more power than you need.
Does my living room have awnings and is usually cool, do I need a larger one?
Not just because it is a living room. If the awnings block the sun and the room maintains a cool temperature, it wouldn't automatically upgrade to the next model. This could be an option; what remains to be determined is how big the living room is and if it is open to other areas.
Does it work to cool two rooms?
I wouldn't buy it to keep two separate rooms cool. It has only one unit inside the house: opening the doors doesn't distribute the cold evenly. For two rooms that you want to use at the same time, it's better to consider a 2x1 system, with one unit in each room.
Can I turn it on with my phone before I arrive?
Yes. It comes with built-in Wi-Fi and can be controlled with the TCL Home app. It also includes a remote control for use without taking out the mobile phone.
Will the complete equipment arrive or do I need to buy anything else?
You receive the indoor unit, the outdoor unit, and the remote control. To get it working, installation and its materials are required; they are not included in the price.
Is the installation included?
No. The installation is quoted separately depending on where it will be placed and the necessary work. Ask for it before purchasing if you want to know how much it will cost you all installed.
What warranty does it have?
TCL indicates 3 years for domestic use in Spain. For this model, we do not have a confirmed extension to 5 years.
