Description
To air condition an open area from the ceiling: cassette TCL M55S3S1 with a nominal cooling capacity of 13,760 frigories/h (16 kW). 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: MT5531. Check PCB and maintenance.
The additional load per length is not confirmed for this reference. Please consult your manual before intervening.
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 M55S3S1
How many frigories does this cassette have?
The TCL M55S3S1 unit has a nominal cooling capacity of 13,760 frigories/h (16 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 MN55S3S1 and proper air distribution. It offers 16 kW nominal cooling; it is not inherently better than a wall-mounted unit. To choose, compare the thermal load, height, position of the people, and installation cost.
Does it cool several closed rooms?
It should not be chosen for that reason alone just because it has 13,760 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 13,760 frigories/h; to determine if it is sufficient, we need to understand the characteristics of the space. Before making a decision, we will review the power and the available space in the false ceiling with you.
Does a large cassette replace several heating points?
Not necessarily. The power of 16.00 kW does not eliminate distances, obstacles, or separated areas. In elongated or compartmentalized spaces, it may be more appropriate to distribute the supply points after calculating the loads.
What does the set include?
Indoor unit cassette MN55S3S1, outdoor unit MT5531, cassette panel NPAN90S1. The TCL series S technical sheet documents the remote control and wall-mounted control for this set. The specific reference of the controls and their photograph are verified with the supply.
What pipe do you need?
3/8″ / 5/8″ pipe. Documented pre-charge for 5 m. The TCL series S technical sheet indicates a maximum of 60 m of travel and 30 m of elevation for M55S3S1. The additional load per meter is still pending from the supplied revision manual.
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?
The exterior is three-phase (380 V published); the table indicates 220 V for the interior. The schematic and the label of the supplied equipment must be checked.
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. The Spanish table TCL series S explicitly indicates it for M55S3S1, with interior MN55S3S1 and exterior MT5531. Control from TCL Home with a compatible network.
How many years of warranty does the TCL M55S3S1 have?
TCL indicates a standard 3-year warranty, and this model is listed for a free extension up to 5 years. The extension requires an eligible purchase in Spain from April 1, 2025, domestic use, registration in the TCL account within 30 calendar days, and validation of the invoice and serial numbers of both units. It is not an automatic 5 years; check TCL's terms and exclusions. Consumer legal rights are not affected.
What data is used when TCL publications differ?
Heat: 17.00 kW according to the Spanish catalog; 18.17 kW on the TCL website. The published weights also differ; confirm the revision to prepare supports and installation. The data is identified by source; revisions are not exchanged, nor is a discrepant figure used as a refilling instruction.
