Description
To distribute air through a duct system: 10,406 frigories/h (12.1 kW) nominal of the TCL M42D1W2 unit. A concealed indoor unit feeds the grille network; the distribution among rooms depends on the duct design, not on having a split in each one. Installation and adaptation of the network aside.
The duct network and the position of the grilles must be adapted to the layout of the property. Having multiple grilles does not imply independent control by room: if you need this, a compatible zoning system must be studied.
Wi-Fi is included to manage the equipment from the manufacturer's compatible application.

What to check before installing TCL M42D1W2
The choice of equipment does not replace the inspection of the installation by a qualified professional.

- Refrigerant connections 3/8″ / 5/8″. The maximum length, the height difference, and the additional load of R32 are calculated using the installation manual of the provided revision.
- The set is single-phase. The installer will check the voltage of the PCB, the protections, the wiring, and the ventilation distances.
- Wired remote control included as per catalog; wireless remote control not included. Control reference to be confirmed when requesting the supply.

Load calculation and documentation
Outdoor unit: MT4212. 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 M42D1W2
How many frigories does this ducted unit have?
The TCL M42D1W2 unit declares a nominal cooling capacity of 10,406 frigories/h (12.1 kW). This is the total capacity that must be distributed through the duct network; it does not correspond to each grille or room.
Can it cool the living room and the bedrooms?
It can be part of an installation that serves multiple rooms, as long as the total load and duct design match its 12.1 kW nominal capacity. It has a single indoor unit (MN42D1W2), not a separate split in each room. It is necessary to check flow rates, pressure losses, and air return for each room.
What happens if some rooms get colder than others?
Before choosing a more powerful unit, it is advisable to check the air distribution through the grilles and ensure that the ducts reach each room properly. This unit offers about 10,406 frigorías/h. Let us know which rooms you want to cool; the installer will also need to verify that the ducts can accommodate the chosen unit.
Can I replace my old unit with this one without making any changes?
It is not confirmed just by matching the cooling capacity. Before replacing it with TCL M42D1W2, check the dimensions and access of the false ceiling, power supply, refrigerant and acceptable pipes, drainage, flow rate, and available pressure. The technical sheet and a review of the installation determine what can be reused.
Can the order be placed only with the available gap?
It is not advisable: the exact inspection of the interior and its layout must be contrasted, in addition to flow, return, and maintenance access. The technical sheet retains the references of the assembly and avoids replacing them with those of another similar inspection.
What does the set include?
Indoor duct unit MN42D1W2, outdoor unit MT4212. Wired remote control included as per catalog; does not include wireless remote control. Control reference to be confirmed when requesting supply.
What pipe do you need?
Liquid 3/8″ and gas 5/8″. The additional load and travel limits must be checked in the exact manual; they are not calculated solely by diameter.
How much false ceiling do you need?
The body is 245 mm high. The mounting, drainage, connections, and service space must be added; that figure should not be taken as the minimum false ceiling.
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. TCL releases Wi-Fi control for this reference and the Spanish distributor announces it integrated into the set. It requires a compatible network and configuring TCL Home.
How many years of warranty does the TCL M42D1W2 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.
