INTENDED USE

The purpose of this unit is to improve the quality of

indoor air. Ventilation is the primary function of the

unit.

The unit is also used for recovering heat energy from

extracted air. Depending on the model, it can be used

for cooling supply air during summertime. It can also be

used for controlling the humidity and carbon dioxide

levels of indoor air.

OPERATION

Well-functioning ventilation creates the foundation for

comfortable living. Mechanical ventilation means that

fresh outside air is distributed into the building, and

used air is blown out. The purpose of ventilation is to

bring clean, ltered air for people and pets inside the

house, and to remove accumulated impurities from the

air.

Heat energy is recovered from the extracted air by the

rotating heat exchanger. The aluminium foils collect

heat from the extract air, and when they rotate to the

supply-air ow, they release the energy.

Every day use of ventilation

Ventilation is controlled with a simple and easy-to-use

control panel that is based on actual use situations.

Operation modes based on these situations cover

all the ventilation needs at your home. Selecting an

operating mode changes the functionality of the

ventilation unit accordingly. The installer of the unit

will apply the operation mode parameters when

commissioning the ventilation unit.

The control panel is normally in stand-by mode with a

dimmed display. You can activate the unit by pressing

7User instructions

Overpressure (replace) mode

If you are going to light the replace, you may need to

use the overpressure function.

WARNING

WARNING: The overpressure mode is primarily

intended to be used only when lighting the

replace, not for providing supply air to the

replace.

TIP: Unnecessary use of the overpressure

function leads to waste of energy.

To select:

1. Press the Mode button for 3 seconds.

The display shows rst briey text on and then

F-PL.

To return to Home mode:

1. Press the Mode button for 3 seconds.

The display shows rst briey text oFF and then

the display returns to the basic view.

NOTE: The Overpressure mode is set for

duration of 10 minutes and can be selected

maximum 2 times a day. When time is expired

the system returns to the previous mode.

NOTE: The Overpressure mode can be set also

by an external replace push button switch (if

installed).

Heating mode

The Heating mode uses the built-in heater to warm up

the supply air.

To select:

1. Press the Temperature button for 3 seconds.

The display shows briey texts HEAt and on and

then the display returns to the basic view.

To return to Home mode:

Eco mode

Selecting Eco mode for your ventilation system means

that you allow the system to make slight changes to

the dened temperature and ventilation values to

save energy. In Eco mode, the system will not react to

temperature changes as quickly as in normal mode,

but waits awhile to see where the temperature is going

before it starts heating or cooling the incoming air.

This green choice will not signicantly aect your

comfort level, but will save you money.

To select:

1. Press the Eco button.

The display shows briey text ECO and then on

and then the display returns to the basic view.

The ventilation system adjusts itself to the new

setting.

To return to Home mode:

The display shows briey text ECO and oFF and

then the display returns to the basic view.

NOTE: The selected Eco mode switches o if

the outside temperature rises over + 25 °C and

switches back on when the outside temperature

sinks below + 25 °C.

USING VENTILATION

EFFICIENTLY

Properly designed and used ventilation saves money

and energy. It also promotes the health of both the

living environment and its inhabitants.

• Always operate the ventilation system according

to the plan specically designed for your premises,

throughout the year.

• Clean or replace the lters when prompted and

vacuum the insides of the unit regularly.

• Open the ventilation unit hatch and take a peek

regularly, for example once a month.

• Dust and other impurities in the air can get the

equipment very dirty. The dirt blocks the lters

and sticks onto the heat exchanger, which makes

ventilation inecient.

• Use the special modes, such as Overpressure only

when really needed.

• Using the special modes unnecessarily increases

your energy consumption.

• Instead or in addition to adjusting your ventilation

system to achieve comfort, you can also use more

traditional methods:

• For example, having the curtains and windows

closed on a hot day to keep the sun out, or

dressing up more warmly on a cold day saves a

lot of energy.

• Only use spare parts approved by Enervent.

• Only use original lters. They are designed to

give maximum performance for your ventilation

system.

• Use the Eco mode ventilation system to help you

save energy and money without compromising

the quality of indoor air.

Using ventilation in cold season

CAUTION

CAUTION: Turning down your ventilation

system may cause serious damage to the

structure of your house.

Do not turn the ventilation down or o even if the

outside temperature falls. Instead of saving you money,

it may cost you even more. Your ventilation system has

been designed by a professional system designer. The

design of the system and the equipment make sure

that changes in the outside temperature have been

taken into consideration. If there are no changes to your

daily routines, there is no need to adjust the ventilation

system.

If you turn down the air ow during cold weather you

increase the risk of ice build-up in your ventilation

unit. This risk is higher during extreme freezing out

conditions and with high indoor humidity (extensive

shower use and lots of drying laundry).

If the ventilation system design needs updating,

contact your system designer.

ADJUSTMENTS

Supply air is too warm

If the air coming from the ventilation system is too

warm:

1. Press the Temperature button to scroll to a

suitable lower input air target temperature.

The temperature marking on the panel changes

and the ventilation system starts adjusting itself to

reach the dened temperature.

NOTE: The unit uses all available equipment

to reach the desired temperature. Lack of

equipment, such as cooling coil, may result in

higher temperature than you have set.

NOTE: Using Eco mode will maximize the heat

recovery also in warmer weather. This can also

result in too warm supply air. In that case turn

Eco mode o.

Supply air is too cold

If the air coming from the ventilation system is too cold:

1. Press the Temperature button to scroll to a

suitable higher input air target temperature.

The temperature marking on the panel changes

and the ventilation system starts adjusting itself to

reach the dened temperature.

NOTE: The unit uses all available equipment

to reach the desired temperature. Lack of

equipment, such as after-heater, may result in

lower temperature than you have set.

NOTE: Lack of maintenance: Clogged lters,

worn out heat recovery drive belt etc. can also

result in cold supply air.

Ventilation is not sucient

If the ventilation is not sucient:

1. Make sure the lters are clean and do not need to

be replaced.

• If the lters are dirty, replace them as

instructed in chapter ”Filters” on page 12.

2. Make sure there are no major changes in your

ventilation since the system was designed and

installed.

• If there have been changes for example in

the number of people using the premises, or

in your routines otherwise, your ventilation

system may need updating. Contact your

ventilation system designer.

Ventilation is noisy

Even though these ventilation units are fairly quiet, they

are never completely silent. However, if the ventilation

system is properly planned and built – no units near the

bedrooms, soundproof doors and muers are used -

the disturbance from ventilation can be diminished.

If the ventilation is unusually noisy:

1. Make sure the lters are clean and do not need to

be replaced.

• If they are dirty, replace them as instructed in

chapter ”Filters”on page 12.

2. Make sure the fans are clean and do not need to be

cleaned.

• If they are dirty, clean them as instructed in

chapter ”Cleaning” on page 14.

3. Make sure that the automatic humidity boosting is

not running.

• Open the Information view and scroll for

parameter n1. If the parameter is visible, the

boosting is on.

NOTE: If the boosted ventilation stays

constantly on, it may be a sign of excess

humidity in the in air. Contact your ventilation

system designer.

Indoor air is too humid

In addition to feeling humidity in the air, you can also

notice excessive humidity by listening to the sounds

of the ventilation. If the automatic humidity boosting

is always on, it may be a sign that there is too much
