Description
To air condition an open area from the ceiling: cassette TCL M42S1S2 with 10,406 frigories/h (12.1 kW) nominal cooling capacity. It is an alternative to consider when there is a false ceiling and you want to free up the walls; it does not replace several splits for closed rooms. Check height, mounting space, and air distribution. Installation is separate.
Before choosing it, it is advisable to check the available height above the ceiling and the location of the equipment. The panel and the control are part of the configuration: in "What is included" you can see which ones are supplied with this reference.
Wi-Fi is included to manage the equipment from the manufacturer's compatible application.

Load calculation and documentation
Outdoor unit: MT4212; factory load discrepancy between documents, check the PCB. Verify the PCB and inspection.
Additional load: 25 × (L − 5) g, only above 5 m and within the maximum travel.
L is the length of the run between the interior and exterior, not the sum of both pipes. The published limit is for equivalent length; fittings must be considered according to the manual. 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 M42S1S2
How many frigories does this cassette have?
The TCL M42S1S2 unit has a nominal cooling capacity of 10,406 frigories/h (12.1 kW). The power refers to the complete unit, not to each air outlet of the cassette.
Is a cassette better than a wall-mounted split for my living room or premises?
This cassette is an option if the space and the false ceiling allow for the installation of MN42SS2 and proper air distribution. It offers 12.1 kW nominal cooling; it is not inherently better than a wall-mounted unit. To choose, compare the thermal load, height, the position of people, and the installation cost.
Does it cool several closed rooms?
It should not be chosen for that reason alone just because it has 10,406 frigories/h. An interior cassette distributes air in the area where it is installed; doors and partitions limit access to other rooms. For closed spaces, consider a multisplit or a duct network designed for them.
What should I check if the space receives a lot of sunlight?
Take into account the square meters of the space, the windows, and the hours of sunlight. This cassette has about 10,406 frigories/h; to determine if it is sufficient, we need to know what the space is like. Before making a decision, we will review the power and the available gap in the false ceiling with you.
Can I place it next to a wall or a beam?
The location must keep the air outlets clear and respect the manufacturer's clearances. Nearby walls, beams, or light fixtures can hinder distribution; the ceiling plan and the return are as important as the 12.10 kW nominal output.
What does the set include?
Indoor unit cassette MN42SS2, outdoor unit MT4212, cassette panel NPAN90S1. Wireless remote control and wall control included as per documented supply.
What pipe do you need?
3/8″ / 5/8″ pipe. Precharge for 5 m; maximum equivalent length 75 m and height difference 30 m. Above 5 m: 25 g/m additional. The installer must check the PCB and review before intervening.
Are the dimensions of the panel the ceiling opening?
No. The NPAN90S1 panel measures 950 × 45 × 950 mm (width × height × depth), but the space and clearances are taken from the installation plan of the unit.
Is it single-phase or three-phase?
It is single-phase. Check the voltage of the PCB and protections with the installer.
Can I buy it with installation?
The price includes VAT and shipping to mainland Spain. Installation is quoted separately based on location, route, and necessary work. The equipment can be purchased now.
Does it come with Wi-Fi included?
Wi-Fi included and control with TCL Home according to the official TCL 2026 catalog: indoor unit MN42SS2, EAN 8720568112541. The reference and the EAN match the component in the Spanish catalog. Please refer to the linked connectivity documentation.
How many years of warranty does the TCL M42S1S2 have?
TCL indicates a standard 3-year warranty for domestic use. We do not advertise 5 years for this reference because it is not explicitly listed in the consulted eligible models. The extended warranty and coverage for professional use must be confirmed with TCL. Consumer legal rights are not affected.
What data is used when TCL publications differ?
Interior height: 245 mm in the Spanish catalog and 290 mm on the TCL website. The published load varies between 2.20 and 1.80 kg; confirm the drawing and PCB. The data is identified by source; revisions are not exchanged, nor is a discrepant figure used as a recharging instruction.
