Frequently asked questions

Questions about MXZ-3F68VF + 2 × MSZ-AY20VGK + MSZ-AY35VGK

How many frigories does this 3x1 air conditioning unit have?

It has a nominal capacity of 5,848 frigories/h (6.8 kW) for the entire unit. It is not 5,848 frigories for each room nor the free sum of the powers of the splits. The available capacity is distributed among the indoor units that are operating; it changes with demand and usage conditions.

Is it suitable for 3 rooms with a single outdoor unit?

Yes: the set includes 2 × MSZ-AY20VGK + 1 × MSZ-AY35VGK and one outdoor unit. There are 3 indoor climate control points. To determine if it covers the specific rooms, it is necessary to check the load of each one and the simultaneous demand against the 6.8 kW nominal of the set; counting rooms is not enough.

Does it fit if the living room needs to be cooler than the bedrooms?

This set combines splits of different models. We can help you see which one fits in each room according to its size and the heat it accumulates. Tell us the square meters of each room, where it gets the most sun, and which ones you will use at the same time. With that information, we can guide you on the combination, without assuming that the living room always needs more power.

Can I add the cooling capacities of the splits to choose it?

No. In Mitsubishi Electric MXZ-3F68VF + 2 × MSZ-AY20VGK + MSZ-AY35VGK, the reference for the published shared capacity is 5,848 frigories/h (6.8 kW) nominal for the set. The class figure or the indoor model number does not directly correspond to delivered frigories. Without the distribution table for the combination, an independent figure per room is not guaranteed.

What does MXZ-3F68VF + 2 × MSZ-AY20VGK + MSZ-AY35VGK include?

1 × MXZ-3F68VF (outdoor unit); 2 × MSZ-AY20VGK (wall-mounted indoor units); 1 × MSZ-AY35VGK (wall-mounted indoor unit); 2 × SH23E (remote control); 1 × SH22Q (remote control). The above composition identifies the units and controls of this offer. The installation is contracted separately.

What measurements should I check before booking the equipment?

Interior MSZ-AY20VGK · height × width × depth: 250 × 760 × 199 mm. Interior MSZ-AY35VGK · height × width × depth: 299 × 798 × 245 mm. Exterior MXZ-3F68VF · height × width × depth: 710 × 840 × 330 mm. These are the dimensions of the indicated components, not the minimum installation space. Also allow for the clearances, connections, and maintenance access required by the manual.

Is Wi-Fi included or is an accessory required?

Integrated Wi-Fi in each indoor unit, with control via MELCloud. No additional adapter purchase is required. The remote control operates via infrared; the Wi-Fi is built into the unit.

What command does the equipment receive?

Include 3 remote controls, one for each indoor unit: 2 × SH23E for MSZ-AY20VGK; 1 × SH22Q for MSZ-AY35VGK.

What changes compared to 20+20+25?

An MSZ-AY25VGK changes to MSZ-AY35VGK; with this composition, it publishes 6.8 kW in cooling and 7.4 kW in heating. The remote control for AY25 and AY35 is SH22Q: it changes the indoor unit and the nominal value in cooling, not that remote control model.

Can I heat just one room?

You can operate each of the 3 indoor units of this AY 20+20+35 with its remote control, without having to keep all of them on. They share the outdoor unit MXZ-3F68VF: they can work in cooling or heating mode, but cannot cool one room while another is heating. The available capacity depends on which units are running.

What is the distance from the rooms where I can place the MXZ-3F68VF?

For the exterior MXZ-3F68VF of this set, the manual allows for up to 25 m of indoor piping and 60 m when summing all branches. The maximum height differences are 15 m between the exterior and interior and 10 m between interiors. The actual length of the piping is measured, not the straight-line distance. The installer must check the diameters, adapters, bends, load, and equipment inspection: these limits are not installation meters included in the price.
