FANS

The fans are powered by energy-efﬁcient EC motors. They are easy to

remove for service and maintenance. The speed of the fans can be ad-

justed independently of each other.

HEAT RECOVERY AND SUPPLEMENTARY HEATING

In climates where the temperature seldom drops below -10 °C, there is

usually no need for supplementary heating. This is because the rotary

heat exchanger recovers enough thermal energy from the extract air (≤

85% h

temp

When the outdoor temperature is below -10 °C and the desired supply

air temperature cannot be achieved, a postheater is required, which is

controlled to maintain the set supply air temperature. In very cold are-

as, the unit can also be supplemented with a heater that preheats the

outdoor air. This heater starts preheating the air when the outdoor

temperature falls below -12 °C.

The electric heaters have an integrated overheating protection function.

NOTE! THE ELECTRIC POSTHEATER IS ONLY ACTIVATED IF THE

IMPELLER IS IN OPERATION.

FILTER

As standard the unit is ﬁtted with a class (M5) ISO Coarse 85% bag ﬁl-

ter. For ﬁlter replacement, see page 11.

DEFROSTING

During cold periods, when frost may form in the impeller, the integrat-

ed control unit automatically activates a defrosting function. The unit

defrosts for 15 minutes every 6 hours if the outdoor temperature is

below -10 °C. The supply air fan stops and the impeller moves forward

in sections.

COOLING RECOVERY

In the summer, if the extract air is cooler than the outdoor air, the rota-

ry heat exchanger starts to recover cooling from the cooler extract air.

This primarily applies if there is some type of cooling appliance in the

house.

ALARMS

The ISYteq Basic control panel (accessory) has a limited alarm

indicator function. The panel indicates, for instance, when there is a

temperature alarm or when the ﬁlter needs replacing.

If the ISYteq Touch 3.5 control panel (accessory) is used, the alarm will

be presented in plain text (see separate instructions).

MOISTURE CONTROL (OPTIONAL)

This function automatically limits the rotary heat exchanger’s moisture

recovery at high indoor humidity levels. This function can also be or-

dered retrospectively to supplement the unit.

CO2 CONTROL (OPTIONAL)

This function regulates towards a preset setpoint. The fan speed is

automatically adjusted to achieve the desired CO

level.

NOTE! CO

control requires a ISYteq Touch 3.5 control panel. This func-

tion can also be ordered retrospectively to supplement the unit.

ETHERNET CONNECTION (OPTIONAL)

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

In that case, the unit is equipped with 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.

To optimize the performance of communication, please follow the rec-

ommendations below.

- Minimize the number of general broadcasts.

- Only send dedicated trafﬁc to the controller.

- Do not attempt to access the web server when using Modbus TCP-IP.

- Maximum of one Modbus message per second is recommended.

Avoid data bursts.

- Only write to Modbus registers when values have been changed.

The unit has a built-in control unit that controls the operation of the

fans, the rotary heat exchanger and any electric heaters.

The unit is controlled via an external ISYteq Basic or ISYteq Touch 3.5

control panel (accessory), see page 6. The control unit should be in-

stalled in a suitable place.

After being adjusted, the unit can also be operated without a control

panel, but only in one operating mode.

The user can select between the following operating

modes:

“AWAY” is used when there is reduced need for ventilation, e.g.

when occupants are on holiday

“HOME” used for normal ventilation ﬂow

“FORCED” is used when there is a greater need for ventilation (au-

tomatically reverts to normal after 120 minutes)

Use the arrow button to switch operating modes (see ﬁgure 2). A LED

shows the current operating mode.

MAINTENANCE AND CLEANING OF HEAT EXCHANGER AND FANS

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

disconnected.

CLEANING OF FANS

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

may only be vacuum cleaned or brushed.

Remove the unit’s front cover (if there is one). Remove the screws on the door and

open the door. The picture shows a unit with right-hand conﬁguration (RDKS-1).

Remove the heat exchanger package from the unit. Disconnect the electrical con-

nection to the impeller motor.

Vacuum clean the heat exchanger or blow clean with compressed air.

Disconnect the impeller from the fan housing by unscrewing the screws on the side

of the fan housing.

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. Be careful to avoid trapping any cables. If necessary, use protec-

tive gloves.

CLEANING OF THE HEAT EXCHANGER

Check that the surface of the rotor is not coated with dust. Clean with

a vacuum cleaner or by blowing through with compressed air. If vac-

uum cleaning is not sufﬁcient, hand-spray with grease dissolving ﬂuid

and then blow clean with compressed air. Use the compressed air to

blow away from the clean side towards the dusty side.

Note! Water, acetone or similar solvents must not be used.

Remove the fan from the unit. Disconnect the electrical connection.

The drive belt and seals may need replacing due to wear and tear.

Check them for damage and replace if necessary. For designations,

see spare parts list on page 33.

OVERHEATING PROTECTION, ROTOR ALARM, TEMPERATURE ALARM, OTHER ALARMS

THERMAL OVERLOAD PROTECTION

The fan motors are equipped with thermal overload protection devices,

which are reset manually by brieﬂy disconnecting the power.

The electric heaters have two thermal overload protection devices, one

automatic and one manual. The automatic overheating protection trips

before the manual one, which means it does not normally need to be

reset.

If the manual overheating protection for the electric heater has tripped

during operation, ﬁrst the power to the unit should be switched off and

then the overheating protection should be reset by pressing the reset

button.

In order to access the button, the electric heater must be disconnect-

ed.

If the manual overheating protection trips again, call qualiﬁed service

personnel.

ROTOR ALARM

If the rotor motor stops and the Tacho signal disappears, ﬁve attempts

will automatically be made to restart the rotor (start/stop). If this does

not solve the problem, the unit will stop and the rotor alarm will be in-

dicated.

TEMPERATURE ALARM

Generates an alarm and stops operation if the supply air temperature

drops below +5 °C. The alarm is disabled during defrosting or dur-

ing forced operation with a 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 various alarms that are not supported by the simple

ISYteq Basic control panel (accessory).

If any of these alarms are triggered, the unit will stop running and all

the LEDs on the ISYteq Basic will be extinguished. This also happens

in the event of power failure. A LED on the control card indicates that

the power is not switched off.

To reset these alarms, the unit must be restarted by pulling out and

reconnecting the plug.

If the ISYteq Touch 3.5 control panel (accessory) is used, the alarm will

be presented in plain text.

If the alarm recurs, service personnel will be called for assistance.

SENSOR ERROR

If any of the temperature sensors starts malfunctioning, the unit will

stop running. To reset, follow the instructions under Other alarms.

EXTERNAL ALARM

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

gered, the unit will stop running To reset, follow the instructions under

Other alarms.

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.

We recommend having a separate extract air device in the kitchen and

a boost damper with dense blades to ensure heat recovery from air in

kitchen.

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 insulation should be installed externally and have a wind-proof

surface.

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

insulated and have a diffusion-proof (moisture-proof) surface. 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.

For designations of the various ducts, see ﬁgure 15 on previous page.

The wall on which the unit is to be installed must be well insulated.

All ﬁgures in this table are recommended values which apply in central Sweden. Please check for local variations.
