FANS

The fans are powered by energy-efﬁcient EC motors.

HEATER

A heater (electric or water coil) is supplied as standard.

TEMPERATURE CONTROL

In cold weather the bypass damper closes and outdoor air is routed

through the heat exchanger in order to recover the heat from the ex-

tract air (winter mode). The heat that the counterﬂow heat exchanger

recovers is generally sufﬁcient.

When outdoor temperatures are low and the desired supply air tem-

perature cannot be achieved using recovered heat alone, the heater

assists.

In warm weather the bypass damper opens and the outdoor air is rout-

ed past the heat exchanger (summer mode).

CONTROL EQUIPMENT

The unit is equipped with an electronic ISYteq Mini control unit.

The control unit is integrated into the unit and controls the

operation of the fans, the bypass damper and the heater.

FAN CONTROL

Three operating modes can be selected via the ISYteq Touch 3.5

control panel:

• “AWAY” (low speed) is only used when the premises are left empty

for an extended period (during a holiday for example)

• “HOME” (normal speed) is used for normal ventilation ﬂow

• “FORCED” (high speed) is used when there is a greater need for ven-

tilation (reverts to normal automatically after 120 minutes)

The speed of the fans can be adjusted independently of each other.

COOLING RECOVERY

In the summer, if the extract air is colder than the outdoor air, the by-

pass damper closes to recover cooling from the colder extract air. This

applies particularly if there is some form of cooling unit in the facility/

house.

DEFROSTING, TERMO ICE

During cold periods when frost forms in the heat exchanger, the Termo

Ice function defrosts the unit and the supply air fan is stopped. Defros-

ting does not start until it is really needed. In other words when much

of the heat exchanger has been covered in frost. This is to allow the

highest degree of heat recovery possible. The Termo Ice system can

detect the difference between frost and condensate.

ETHERNET CONNECTION (ACCESSORY)

This function can be used to connect the unit to an existing network.

The unit has an integrated web server, which makes it possible to read

and change certain parameters via a web browser.

The connection can also be used for connection to a superior system

via Modbus TCP/IP.

CLEANING OF THE HEAT EXCHANGER

Check that the heat exchanger ﬁns are not coated with dust. Clean by

vacuuming or using compressed air. Or spray them with water.

Alternatively clean them using a degreasing agent (ordinary washing

up liquid for example) and rinse clean with hot water.

NOTE! Do not soak the heat exchanger! Do not use dishwasher deter-

gents or lye! Do not poke the air ducts with a sharp object. Allow to dry

before reassembly.

MAINTENANCE AND CLEANING OF HEAT EXCHANGER AND FANS

Pull the heat exchanger out of the unit. During reassembly, check that the seals are

positioned correctly.

Vacuum or spray the heat exchanger with water

GENERAL

The fans, ﬁlters and heat exchanger are very important for the opera-

tion and economy of the unit. For this reason, it is crucial for them to be

kept clean and in good condition.

We recommend a general check-up every 6 months. For safety rea-

sons, general caution should be observed during maintenance of the

unit. If necessary, use protective gloves.

Before cleaning the heat exchanger, fans etc., the unit should always have the power

disconnected. Pull out the plug and open the cover.

CLEANING OF FANS

Note that the fans must not be cleaned with water or other ﬂuids; they

may only be vacuum cleaned or brushed.

2. Disconnect the electrical connection and remove the fan from the unit.

3. Disconnect the impeller from the fan housing by removing the four screws on

the side of the fan housing.

4. Clean the impeller housing and the fan blades with a brush.

5. Reinstall the fan.

1. Unscrew the screws on the cover panels above the fans.

CONDENSATION, WATER IN THE UNIT

When the unit is running moisture condenses from the extract air. This

is greater during autumn and winter. The amount of moisture in the

extract air depends on various factors, during food preparation and

showering for example. A new house gives off a lot of moisture for the

ﬁrst few years.

In the bottom of the unit is a drain hole for condensate drainage. Check

that the drain hole is not blocked at regular intervals.

At the end of the summer the water in the water trap may have evapo-

rated. This can result in a gurgling noise. Remedy this by pouring water

into the drain hole to ﬁll the water trap.

FILTER ALARM AND FILTER REPLACEMENT

If the ﬁlter needs replacing ISYteq Touch 3.5 generates an alarm.

The supply air and exhaust air ﬁlters should normally be replaced eve-

ry six months. In dirty areas, the ﬁlters may need to be replaced more

frequently.

A built-in timer is normally set to provide a ﬁlter replacement reminder

every six months.

To replace the ﬁlter, follow the steps below.

1. Disconnect the unit from the power supply by pulling out the plug.

2. Open the unit, see previous page.

3. The supply ﬁlters (coarse ﬁlter and ﬁne ﬁlter) are suspended on a

spring-loaded bracket. Move the spring-loaded plate to one side to

remove them. To minimise soiling take both ﬁlters out at the same

time.

4. Remove the extract air ﬁlter sitting loose on the heat exchanger.

5. Install new ﬁlters

6. Close the unit and insert the plug

7. Press the alarm symbol to reset the ﬁlter alarm. Then acknowledge

the ﬁlter alarm, see the ﬁgures below.

If the ﬁlters are replaced before the alarm is generated, reset the ﬁlter

alarm in the Settings menu, see the ﬁgure below.

UNIT WITH A WATER COIL

On units with a water coil the supply air temperature is adjusted using

the thermostat valve on the coil inlet line, see the ﬁgure below.

FROST PROTECTION

The frost monitor is used to prevent frost damage to the water coil

when outdoor temperatures are low. The frost protection sensor gene-

rates an A alarm that stops the unit when the water temperature drops

below 10 °C.

Investigate why frost protection tripped and then reset the alarm.

RESETTING THE THERMAL OVERLOAD PROTECTION

The fan motors are equipped with thermal overload protection that is

reset manually by temporarily disconnecting the power.

The electric heaters have dual thermal overload protection devices,

one that resets automatically and one manually. The automatic thermal

overload protection device trips before the manual one.

If the manually reset thermal overload protection device has tripped the

power must be disconnected.

Let the electric heater cool for a few minutes before unscrewing the

plastic cover over the reset button. Reset the thermal overload protec-

tion device by pressing the reset button.

If the manually reset thermal overload protection device trips again, call

out service personnel.

TEMPERATURE ALARM

The temperature alarm stops the unit if the supply air temperature

drops below +5 °C. The alarm is blocked during defrosting or during for-

ced operation via the cooker hood. A 10-minute delay ensures that the

supply air temperature has time to rise if operation has been stopped.

OTHER ALARMS

The unit has a number of other alarms. These are displayed in plain

text on the ISYteq Touch 3.5 control panel.

EXTERNAL ALARM

An external alarm can be connected to the unit. If this alarm is trigge-

DUCT CONNECTION

Exhaust air from the unit may only be connected to a ventilation duct

intended for this purpose. Connection must not be made to a smoke or

gas ﬂue. In case of extract air ventilation in premises where a smoke

or gas ﬂue is used (for instance, an open ﬁreplace or heating stove),

an adequate supply air ﬂow must be ensured A kitchen ﬂue must be

installed in accordance with applicable regulations.

DUCT CONNECTION, DUCT INSULATION

Note! During installation, the instructions regarding unit installation and duct insulation must be adhered to without deviation.

Otherwise, there is a risk of condensation and moisture resulting in major damage.

DUCT INSULATION

In order for the installation of the unit to be effective, it is crucial that

the installation of the ventilation ducts in the unit, as well as the instal-

lation of ducts through external walls containing insulation and vapour

barriers, roofs and joists, is executed in a professional manner. Other-

wise there is a risk of condensation, resulting in moisture damage.

If older units are replaced, it is also necessary to inspect ducts and

duct insulation for damage and ensure they are of adequate quality.

Supply air ducts (T) and extract air ducts (F), i.e. ducts containing warm

air, which are located in unheated spaces, must be insulated. The insu-

lation should be installed externally and have a windproof surface layer.

Outdoor air ducts (U) and exhaust air ducts (A), i.e. ducts ﬁlled with cold

air, which are located inside the building’s vapour barrier, must be in-

sulated and have a diffusion-proof (moisture-proof) surface layer. Given

the high degree of heat recovery achieved by the unit, the exhaust air

also gets very cold and must be thermally insulated. Moreover, ducts

which run alongside each other must have a common vapour barrier.

Ducts between the cooker hood, if ﬁtted, and the unit and exhaust air

duct are to be regarded as kitchen ﬂues. This means that particular

measures must be taken; see the table below.

For the designations of the various ducts, see "Duct deﬁnitions" on the

next page.

There are four adjustable

feet on the underside of the

unit used to level it.

CONDENSATION DRAIN

There is a connection (1/2" internal thread) at the bottom of the unit for

draining condensation.

Use a length of 12 mm pipe or rigid hose to route condensate to the

ﬂoor gully or to the wash basin/sink water trap.

Do not connect the condensation pipe to the outﬂow directly. Always

create a water trap on the pipe by bending it as shown in the adjacent

ﬁgure. The height of the water trap is to be 50 - 100 mm. Ensure that

the pipe slopes downwards for its entire length. Fill the water trap.

Important! Do not install the unit by a wall that borders a

bedroom.

INSTALLING A WATER HEATER

Figure 8. Connecting a water heater

INSTALLING A WATER HEATER

Connect the water coil to the heating system in the home; in parallel

with the radiators for example. Generally, thanks to the unit’s high efﬁ-

ciency, no more heat output is needed than connecting the water coil to

the same branch as the underﬂoor heating for example.

Create an inspection opening if the connections are in a space above

a suspended ceiling. Install a bleed valve at the highest point of the

return line.

When the circuit has been topped up and bled, ensure that the water is

circulating in the coil before commissioning.

The system may need to be bled again after a few days. Ensure that

the air ﬂows are calibrated before the water is connected. There must

be a continuous ﬂow of water in the coil in winter due to the risk of

frost.
