Preselecting the target value and automatically maintaining the desired temperature in the room
The integrated thermostat always indicates the current room temperature on the LED display. To start the cooling process, simply set your desired temperature value from 16°C to 31°C, and the device will start cooling down the room air as you wish. To ensure the target temperature is maintained on a permanent basis, the air conditioner automatically ensures that the refrigerating compressor will be switched off upon reaching the preset target temperature. The device will only resume cooling once the temperature value is exceeded. The automatic operation is the reason why the air conditioner of energy efficiency category A operates in a particularly power-saving and economical way.
Can also be used as fan – with or without cooling function
In addition, the compact all-rounder is equipped with an integrated fan with 3 fan stages. With a flow rate of up to 340 m³/h, this fan provides for air circulation and fresh breeze in the room – even with the refrigerating compressor inactivated. If desired, you can switch on the swing function to evenly distribute the air current in the room. To filter out fluff, dust and animal hair from the breathing air as well, an easy-to-clean air filter is integrated on the back of the device.
The dehumidification function produces relief with respect to muggy room air
Hot and muggy? No need to bear this! The 3-in-1 air conditioner can also be used to fight high humidity levels. The dehumidification performance of 1.3 l per hour allows the device to actively extract humidity from oppressive and muggy air. The result are noticeably more agreeable ambient conditions. In addition, dehumidification prevents unhealthy mould growth. Due to internal condensate recycling the collection container only rarely needs to be emptied: The condensed water is reused for cooling the condenser by means of an intelligent recycling system. Consequently, the majority of water simply evaporates.
Feel-good climate all year long
The 3 operating modes cooling, ventilation and dehumidification can be used independently which allows you to use the practical air conditioner PAC 3500 S not only in summer time, but 365 days throughout the year.

Propane (R290) as environmentally friendly refrigerant in air conditioning systems
Every year, several million tons of harmful CO2 emissions (greenhouse gas) are emitted to the atmosphere due to synthetic refrigerants. For this reason, the utilization of alternative refrigerants has become one of our key objectives. By using propane (R290) as refrigerant this air conditioner makes a valuable contribution to protecting our climate.
The natural refrigerant propane (R290) is an organic compound belonging to the group of hydrocarbons. Unlike synthetic refrigerants the environmentally friendly propane (R290) comes with neither ozone depletion potential (ODP = 0) nor a noteworthy greenhouse effect (GWP = 3).
Additional bonus for the environment: Owing to its excellent thermodynamic properties, propane (R290) is a particularly energy-efficient refrigerant thereby additionally reducing your energy costs.
Cool room air without drilling or using wall plugs
Whether in living room, bedroom or work space – if you prefer not to set up the local air conditioner PAC 3500 S in the same room all the time, it can be conveniently moved from one location to another thanks to its smooth-running wheels. Unlike permanently installed air conditioning systems, you can use a local air conditioner wherever cooling is currently needed – no need for drilling, screwing and using wall plugs. All you have to do is to fix the exhaust air hose (included in the scope of delivery) in a window opening or doorway, and you can directly start cooling down the room! In order to make sure there will be no warm air entering the cooled room through windows or doors, we offer the AirLock window and door seals as an optional accessory. This enables you to cool even more efficiently. Further will be provided to you in the info box below.
Operation via remote control
All functions and settings of the air conditioner PAC 3500 S cannot only be made via the LED control panel but also from your seat by means of the remote control.
The practical timer function makes it possible to switch the device on or off individually after a pre-programmed time. This ensures that the device will switch off automatically in the office in the evening, or allows you to wake up with pleasant cooling in the morning.
Night mode for a refreshing sleep
To ensure that you can go to have a good night's rest even in very hot summer nights, the comfort air conditioner PAC 3500 S is provided with a night mode that allows to gradually increase the temperature. After one hour the preset temperature will automatically increase by 1°C, after another hour again by 1°C. This temperature level will be kept throughout the entire night. This way, you'll fall asleep in pleasantly cool room air and to enjoy a restful sleep without going hypothermic. Hint: if required, the timer can be additionally used to switch off the device automatically at nighttime.
Ideal air distribution via swing function
The on-demand swing function provides even cooling throughout the room. The air outlet automatically swings from the bottom to the top in order for the cold air distributing in an optimal way.
All in all, the air conditioner PAC 3500 S does not only convince with its performance, but also with all the comfort functions – providing an agreeable room climate any day of the year.
Calculation of the required cooling capacity
Find out how to easily calculate the cooling capacity required for your living and office spaces.
How much power is required to cool a room? The rule of thumb: Every cubic metre of room volume requires a cooling capacity of 30 watts (1 m3 = 30 W).
Using this blanket value the required cooling capacity can be determined quickly and easily for every room size. Example: Assuming a room with 46 m² of floor space and a room height of 2.5 m.
The resulting calculation reads as follows:
Room volume calculation:
46 m² of floor space x 2.5 m ceiling height = a room volume of 115 m³
Calculation of the cooling capacity required for the room volume:
115 m³ cubature x 30 watts of cooling capacity = required cooling capacity of 3,450 watts
Conversion from watt to kilowatt:
3,450 W = 3.5 kW
Result: In a room with 46 m2 of floor space and a height of 2.5 m you need an air conditioner with a cooling capacity of 3.5 kW – such as the PAC 3500 S.
This is only a rough calculation formula for living and office spaces with modern insulation (passive house standard), though. The required cooling capacity further depends on the room's "thermal load": For selecting an appropriate air conditioner, the factors of insolation, insulation, window dimensions, the number of persons as well as the heat sources play an equally important role.

AirLock window and door seals
ACCESSORY TIP: AirLock window seals prevent warm air from streaming back into the room you are trying to cool.
The warm air is discharged through an air conditioner's exhaust air hose and thus through a window into the open air. In order to keep the warm air from streaming right back into the room through the window gap we recommend using AirLock window or door seals.
Suitable for windows with a maximum perimeter of up to 4 metres is the window seal AirLock 100. The hose can be attached to any type of window (casement, bottom-hung or skylight windows). With the Velcro® tape mounting between window and frame only takes a few steps. This ensures an optimal cooling efficiency in the room and substantially reduces the consumption costs of your air conditioner.
Also perfect for floor-to-ceiling windows or balcony and patio doors.
The convenient door and window seal AirLock 1000 was specifically designed for sealing floor-to-ceiling windows or balcony and patio doors – it is the only window seal on the market that has a perimeter of up to 5.6 metres. The AirLock 1000 can be used for both one- or two-hose devices. Further information on all available AirLock versions is provided here.

A boost of freshness: Enjoy maximum refreshment anywhere in the room!
Do you want to additionally support the effect your air conditioner has? In order to really distribute the cool air into every last corner of the room we recommend using the powerful fan TFH 2000 E with turbo spin technology. The extremely compressed turbulent air flow gushes out of the TFH 2000 E as tornado-like air column that revolves around itself and advances deep into the room. The air current breaks through warm and cold room air zones mixing it all up. The exiting air current encounters the opposite wall or the ceiling and from there is deflected to all sides.
In a constant circulation the air returns to the rear of the fan flowing along the side walls and the ceiling. It is sucked in once more to start a new cycle. This effective turbo spin method ensures maximum circulation and mixing of the room air. The temperature difference between cold air near the ground and warm air just beneath the ceiling is substantially reduced, instead the air temperature in the entire room is noticeably evened out.
