Description

To distribute air through a duct installation: 13,760 frigories/h (16 kW) nominal of the TCL M55D3W1 unit. A concealed indoor unit feeds the grille network; the distribution between 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.

Guide

What to check before installing TCL M55D3W1

The choice of equipment does not replace the inspection of the installation by a qualified professional.

Reserve space for the interior of 250 mm in height, its connections, the drainage, and the maintenance access points. The duct network and the grilles are sized separately.
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 outdoor unit requires three-phase power supply; the catalog distinguishes between indoor power supply of 220 V and outdoor of 380 V. The installer will check the network, protections, and PCB.
Wired remote control included as per catalog; wireless remote control not included. Control reference to be confirmed when requesting the supply.

It can be part of an installation that serves multiple rooms, as long as the total load and duct design match its 16 kW nominal capacity. It has a single indoor unit (MN55D3W1), not a separate split in each room. Airflows, pressure losses, and air return for each room need to be checked.

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 13,760 frigorías/h.
