Ebac 38500 smart control

Get the Smart Control advantage

Smart Control is much more sophisticated than humidistats. It monitors the moisture levels in your home and controls the dehumidifier to prevent damp and condensation.

PCB 2 1

The biggest improvement in dehumidifier control systems this century

Smart Control automatically measures and remembers the humidity levels in your home. It then automatically switches on the dehumidifier when the levels start to rise and switches off when the humidity levels fall.

Front 3

Over 100,000 Ebac customers have switched to Smart Control

Humidistats were once the only way to control a dehumidifier until Ebac invented Smart Control. Now customers choose automatic Smart Control over older humidistat controlled dehumidifiers.

One touch and leave Smart Control to do the rest

Smart Control is far more convenient as it prevents constant manual adjustment and saves up to 30% wasted in running costs. Faster solution to the problem of damp and condensation with lower running costs.

Why you need Smart Control

The optimal level of humidity in your home variers throughout the day. The weather, temperature and moisture created from washing, cooking, breathing all impact the relative humidity level. Smart Control tracks and varies the dehumidifier controls automatically to take account of all these variables so you don’t have to.

FAQ

You may have heard that picking the right dehumidifier can depend on the size of your home. That’s not entirely accurate, for example, 2 people in a 5 bedroom house will need to remove less moisture than 2 people in a 2 bedroom house, because the bigger house has more capacity to hold the moisture.

Dehumidifiers have different extraction capacities and as a general guide, the more people in the home, the more excess moisture that needs to be removed. However a unit with a larger capacity will cost less to run than a smaller unit, providing it has a good control system. An “oversized” unit will run less than a smaller unit to extract the same amount of moisture. They usually extract more moisture per unit of electricity and by running less frequently they last longer. Our dehumidifiers are labelled with suitability, based on occupants, in order to help you decide which dehumidifier is right for you. We’d recommend watching our how to choose a dehumidifier video at https://www.ebac.com/dehumidif... for more information on dehumidifier suitability.

The extraction rate is the amount of water that can be extracted in 24 hours.

The extraction rate on a dehumidifier is the amount of water your dehumidifier will extract per day and the water container size is the amount of water your dehumidifier can hold at any one time.

The cost of running a dehumidifier is reduced greatly with Ebac’s Patented Smart Control.

Smart control can save about half of the running cost of a typical dehumidifier, between £30 and £55 per annum.

An Ebac dehumidifier from the 2000 series will cost around 23p to remove a litre of water, a typical saving of 14p per litre of water extracted.

The only thing you should need to replace on your dehumidifier is the filters as and when required.

You should start to notice an improvement in your condensation after just 1 day; however, it could take up to a month to get excess moisture in your home under control.

We are so confident that an Ebac dehumidifier will resolve your condensation problem that we are offering a 30 day condensation cure guarantee. This is a no quibble money back guarantee. If you are not satisfied with your Ebac dehumidifier, we will refund your purchase price.

The list is virtually endless; running a shower or bath, boiling a kettle, cooking a meal, doing the dishes and drying laundry all increase the level of moisture in your home.

Even something as simple as breathing, the weather and climate can add to the problem, creating condensation and damp.

This depends on how much excess moisture is in the air. At first you will probably find your dehumidifier collects as much as 2 containers of water per day, but after it removes the initial moisture from the air it will slow down and you will probably find yourself emptying the water container every 1-2 days.

Two people will generate 24 pints of moisture at home in one single day and up to two pints of this moisture cannot be absorbed by your home.

No. Our Smart Control works by removing excess moisture within the air rather than working to a specific RH, as this is by far the best and most efficient way to run.

Ebac have developed a way of controlling your dehumidifier, called Smart Control.

Smart Control is an intelligent electronic software that replaces a normal humidistat.

Smart Control is unique as it takes readings throughout the day allowing it to determine, with an algorithm, the best time to run. The optimum relative humidity varies depending on the activities within your home and the weather outside. As the optimum relative humidity changes this means you would need to change the humidistat on your dehumidifier regularly; some dehumidifiers only have settings that are in 5% steps. This would mean that if the optimum is 47% you could chose 50% which means the dehumidifier will not run enough, or you could chose 45% it means the dehumidifier is running too much.

Smart Control is more effective at eliminating condensation and damp; it’s also more energy efficient and can save about half of your running costs, between £30 & £50 per annum.

Smart Control is fully automatic. Once you switch your dehumidifier on and select Smart Control, you don’t need to make any adjustments to the controls; it simply runs and sleeps when it needs to.

We are so proud and sure of the quality of our products that when you buy a dehumidifier from us you will receive a standard warranty which varies by model type; please see our website for confirmation of standard warranty terms. We also offer you the option to upgrade this term to a maximum 5 year warranty at a supplement.

Yes! Excess moisture can cause damp and mould, which produces allergens (something that causes allergies). These can be harmful to everyone but especially to babies, children, elderly people and people that suffer from asthma and have skin problems.

In order to continue to operate effectively, a dehumidifier needs to defrost, just like your freezer. A dehumidifier in defrost mode is not removing moisture, so defrosting should be minimised. Ebac’s Patented Intelligent Defrost optimises the defrost frequency and duration, keeping the dehumidifier running more frequently and more efficiently. Ebac dehumidifiers are the only dehumidifiers that do this.

The only thing you should need to replace on your dehumidifier is the filters; this should be done every 3 months.

The first thing to check is that the dehumidifier is not on air purification mode (see instruction manual for details). No water is collected in this mode. The second thing to check is that your filters are not clogged up. Remove the filter and run your machine for 24 hours without the filter. If it now collects water, you need to buy a new filter. If the machine is still not collecting water then call our customer services team on 0345 805 0000 who will arrange for your machine to be looked at by our in house service engineers.

If you are running your dehumidifier on Smart Mode it sometimes appears that the dehumidifier is always on or not on at all. This is particularly the case in the first few days of running the dehumidifier. The way that Smart Control works is to constantly monitor the excess moisture in the air and use its artificial intelligence to calculate exactly when it needs to operate and when it needs to be off. This makes it the most efficient dehumidifier on the market. So sometimes it may appear to be on or off for no reason, but trust Smart Control to know best. Smart Control dehumidifiers are designed to be left plugged in 24 hours a day and if you do unplug the machine, the learning process will start again, so the machine will be operating more after turning it back on.

This shows that your dehumidifier is doing a great job and bringing the excess moisture in your house under control. The time between emptying buckets is likely to keep diminishing unless something changes within the house.

For tackling problems like condensation we would recommend placing your dehumidifier in a central place, such as a hallway, keeping all doors slightly a jar. If you have certain problem areas that you would like the dehumidifier to fix then simply place it in that room/area until the problem is under control, then move the dehumidifier to a central place.

We suggest you vacuum your filters monthly to ensure optimum performance. Alternatively you can purchase replacement filters from the accessories section on our website.

All Ebac dehumidifiers offer permanent drainage functionality. In order to take advantage of such functionality you can purchase a permanent drainage kit direct from Ebac – they’re simple to use and offer a simple solution.

Using a dehumidifier to dry your clothes is one of the great advantages of owning a dehumidifier. A dehumidifier is a cheaper alternative to a tumble dryer with no shrinking and a lot less creasing of your garments. It is also great for any clothes which cannot be tumble dried. All you need to do is to put your clothes on a clothes airer in a room with the door left ajar and make sure that your dehumidifier is switched on. If your dehumidifier has a dedicated laundry mode, use this, if not make sure the fan speed is switched to full. It takes on average around 8 hours to dry laundry with a dehumidifier.

No, your dehumidifier is only extracting excess moisture so your fish are completely safe.

No. Although the water has been filtered it is not clean enough for drinking. However it can be used for watering plants, in a steam iron etc.

Your dehumidifier will only remove excess moisture from the air, if there is no more moisture in the air the dehumidifier can’t collect it this will not dry the air out.

Running a dehumidifier from early October until the spring is generally sufficient, as more moisture is generated during the winter months.. It’s also better to start using your Dehumidifier before the winter starts; this reduces the risk of moisture soaking into your walls. If you do start your dehumidifier part way through the winter, it is advisable to run it continuously for around 2 weeks to ensure your home is properly dried out.

90% of homes can produce 3- 5 pints per day, but every home is different. For example, it’s not unusual to find next door neighbours in almost identical homes with the same family size producing different amounts of moisture. There’s no hard and fast rule about how much moisture to take out, but you will soon know if your dehumidifier is working effectively as condensation will start to disappear and your home will feel much drier and healthier.

The way a Dehumidifier works is similar to the way condensation forms on a cold window. A Dehumidifier contains a compact refrigeration system which makes it the coldest place in the house. Air is drawn into the Dehumidifier where any moisture in the air condenses on the hydrophilic coils and is then collected into the easy pour water container.

If you regularly see condensation on your windows, or damp and mould spots in the corners of cold or rarely used rooms, the air in your home probably contains excess moisture. If you don’t do anything about it, this moisture can damage your carpets, curtains, furniture and even your walls. You need a Dehumidifier to remove this excess moisture before it becomes a serious problem.
