The Telair DualClima 8400H black (Total Black) is a roof air conditioner with heat pump for motorhomes, campervans and caravans from 6.5 to 8 m, in the dark-cased version that Teleco designed for vehicles with black, grey or coloured bodywork. It cools with 2.50 kW (8,500 BTU/h), heats with 2.46 kW and fits the standard 40 x 40 cm rooflight opening. It's the unit many customers search for as the "Telair Dual Clima 8400H", in its black version with factory code 8400HN.
Total Black: the DualClima 8400H in black
Teleco launched the Total Black line in 2023, as more and more motorhomes and campervans now come with painted bodywork, coloured cabs or dark vinyl wraps. On those roofs, a white unit doesn't always match. That's why the DualClima 8400H is also made with a dark grey ABS casing, which we call black in the shop.
Only the colour changes. According to Teleco, the black version has the same performance, weight and dimensions as the white one. Prefer the white casing? You'll find it in the Telair DualClima 8400H white.
An ultra-slim diffuser that sends the air where you need it
Inside the vehicle, the only part of the DualClima 8400H you'll see is its diffuser. It's just 4.9 cm thick and has a sloped profile on all four sides, so it fits in without clashing with your cupboards. What's more, its two main outlets, front and rear, adjust both horizontally and vertically. With the flow divider, you can split the air between the two outlets or send it all to one, towards the bed, for instance.
The diffuser itself has an LED display showing the inside temperature, two indicator lights that tell you whether it's cooling or heating, and a two-bar LED ambient light that you switch on and off with the remote.
Cooling and heating for motorhomes from 6.5 to 8 m
Teleco recommends the Telair DualClima 8400H for vehicles from 6.5 to 8 m long. In summer it gives 2.50 kW of cooling with an airflow of up to 480 m³/h, and the manufacturer rates it for tropical use up to 55 °C. While it's cooling, it also dehumidifies the air inside.
In spring and autumn, the heat pump works as a low-consumption heater: it gives 2.46 kW of heat while drawing 950 W, more than double the energy it consumes. According to Teleco, it works effectively down to around 4 °C outside. From 15 °C downwards, the heating output gradually drops, and below 4 °C it falls a great deal. For cold winter nights, use it alongside your vehicle's own heating.
It also uses R32 gas, with a global warming potential (GWP) of 675. According to Teleco, this pollutes 70% less than the gases used previously.
Power consumption: campsite hook-up, generator and 230 V
The DualClima 8400H runs on 230 V - 50 Hz. It draws 990 W (4.3 A on average) when cooling and 950 W (4.1 A) when heating. On start-up it pulls 18 A for 150 milliseconds.
- On a campsite hook-up: a 6 A hook-up gives around 1,380 W at 230 V. The average consumption fits, but with little to spare, so don't run the kettle, microwave or hairdryer at the same time. Whether the start-up peak trips the hook-up depends on each campsite's own trip switch.
- With a generator: Teleco specifies a 2200 W generator.
- Always on 230 V: this isn't a 12 V unit; it needs a campsite hook-up, a generator or mains power.
Controls: AUTO function, remote control and optional Wi-Fi
With the AUTO function, the unit chooses the fan speed by itself and decides whether to cool or heat to keep the temperature you've set. If you'd rather decide for yourself, there are 3 fan speeds to choose from.
The infrared remote control has a programmable on/off timer, a button for the diffuser light and an LED torch. According to the Telair 2026-27 catalogue, it also supports Wi-Fi control from your phone with the ICW interface, and is compatible with CI-BUS and the Teleco HUB via an interface. None of the interfaces are included.
Maintenance is straightforward: the internal filters lift out, wash clean and go back in. It also has anti-freeze sensors to protect the unit.
Fitting into a 40 x 40 cm rooflight opening
The Telair DualClima 8400H fits over the standard 40 x 40 cm rooflight opening without affecting the vehicle's aerodynamics, and suits roofs from 30 to 70 mm thick. The roof unit weighs 36 kg and measures 23.9 cm high, 98 cm long and 65 cm wide: factor this into your payload and the free space on your roof.
Installation isn't included. We recommend having it fitted by a professional workshop, who'll check the roof and the 230 V wiring, and who you can ask about anything relating to your vehicle's paperwork.

|---|
| Vehicle length | 6.5 to 8 m | 8 to 10 m |

If your motorhome or caravan measures 8 to 10 m, take a look at the Telair DualClima 12500H. And if you'd like to compare it with other models, you'll find the whole range in our motorhome and caravan air conditioners collection.
Who is the Telair DualClima 8400H black for?
It's for you if you have a motorhome, campervan or caravan from 6.5 to 8 m with black, grey or coloured bodywork and want a roof air conditioner that matches it. It's also for you if you're after a single unit to cool down in summer and take the chill off in spring and autumn, with a diffuser that barely takes up any room inside. In short, you get all the performance of the DualClima 8400H with a casing that won't look out of place on your roof.
FAQs about the Telair DualClima 8400H black
What's the difference between the black and white DualClima 8400H?
Just the colour of the casing. The black version (code 8400HN, Total Black line) has a dark grey ABS casing and, according to Teleco, keeps the same performance, weight and dimensions as the white one. If you'd rather have white, it's available as the Telair DualClima 8400H white.
How much power does it use? Can I run it on a 6 A campsite hook-up?
It draws 990 W when cooling (4.3 A on average) and 950 W when heating (4.1 A); on start-up it pulls 18 A for 150 ms. On a 6 A hook-up, the average consumption fits, but with little to spare: don't run other high-power appliances at the same time. Whether the start-up peak trips the hook-up depends on each campsite's own trip switch.
Does it work with a generator? How many watts do I need?
Yes. Teleco specifies a 2200 W generator for this model. It always runs on 230 V - 50 Hz: it isn't a 12 V unit.
Does it fit a 40 x 40 cm rooflight opening? What roof thickness does it need?
Yes. It fits the standard 40 x 40 cm rooflight opening and suits roofs from 30 to 70 mm thick. If your roof has different dimensions, check with your workshop before you buy.
What length of motorhome or caravan is it suitable for?
Teleco recommends it for vehicles from 6.5 to 8 m. If yours measures 8 to 10 m, the DualClima 12500H is the better fit; and for 6 to 7.5 m, there's the Silent 3 8100H black.
Does it work as a heater in winter? Down to what outside temperature?
With its heat pump it gives 2.46 kW of heat. Teleco states it's effective down to around 4 °C outside: from 15 °C downwards the output starts to drop, and below 4 °C it falls a great deal. It's ideal for spring and autumn; in the depths of winter, rely on your vehicle's own heating as well.
Is it noisy? Can I sleep with it running?
Teleco has designed the DualClima range with low noise in mind, both inside and outside the vehicle, but doesn't publish a decibel figure, so we won't make one up. At night you can turn it down to the lowest speed and use the timer so it switches itself off.
What's included and who fits it?
It includes the roof unit, the internal diffuser, the remote control and two washable filters. Installation isn't included: we recommend a professional workshop, who'll check the roof and the 230 V wiring.
