SafetyPower supply

CAUTIONAlways disconnect mains electricity to the unit if a fault occurs which cannot be rectified via thecontrol panel.

CAUTIONIf a fault occurs on the electricity-conducting elements of the unit, always contact anauthorised electrical installer to rectify the fault.

CAUTIONAlways disconnect mains electricity to the unit before opening the doors, e.g. for installation,inspection, cleaning and filter change.

Disposal

Ventilation system

Nilan units mainly consist of recyclable materials. They should therefore not bedisposed of with household refuse. Take them to your local recycling centre.

The CTS150 control panel provides the following functions:1. Setting fan speeds: 0 (off) - 1 - 2 - 3 - 42. Green diode: On when the unit is running3. Setting low humidity: Can be set between 15 and 45%4. Red diode: Flashes in the event of an alarm

AlarmsIf the unit is in alarm mode, the RED diode on the CTS150 control panel will flash.

Alarm description

ID Alarm Critical Signal

1. T3 temperature sensor missing No



4. temperature sensor missing No

5. De-icing alarm No

6. Filter alarm No

If the unit records more than 20 de-icing registrations within 24 hours, the de-icing alarm (ID = 5) istriggered

Reset alarm:1. Turn the fan speed selector as follows: → 0 → 4 → 02. Turn the selector to the fan speed required

ATTENTIONIn some software versions the filter alarm can trigger a (ID = 2) alarm. The alarm can bedeactivated by turning the fan speed selector as follows: → 0 → 4 → 0.

Fan speedRecommended fan speed setting in relation what the installer set.

0 The system may only be switched off, for example, in an emergency where residents are askedto go inside, close doors and windows and shut down the ventilation system.NB! When the system is shut off for longer periods, condensation can form in the ductwork,which can cause mould.

1 Use this setting if you are away from home for some time, e.g. on holiday.NB! When the system is set to low humidity, it can be set at fan speed 1.

2 The system is set at fan speed 2 during normal operation. The air volume at fan speed 2corresponds to the basic air volume set for the home.NB! Automatic humidity control changes the system's function, i.e. it runs at high or low fanspeed as necessary.

3 Use this fan speed when you have visitors in your home or if you have lit candles.NB! Don't forget to return to level 2 when your visitors have left!

4 Use this fan speed if holding a party with lots of guests for example.NB! This level can also be used to run a cooker hood (if your cooker hood is connected to theventilation system).

Humidity controlHumidity control overrides the setting on the control panel.

We recommend that you set the system to run at low ventilation when humidity in your home getsbelow 30%. You can set low ventilation at low humidity in the range of 15 to 45%. We recommend asetting of 30%.

The integrated humidity control system will control the ventilation level automatically on demand. Thesystem measures air humidity all the time, and calculates an average level for the last 24-hour period.This level is the basis for ventilation control.

In the event of longer periods with freezing outdoor temperatures, air humidity in the home may fall toan low level. When air humidity indoors is too low, the ventilation level is reduced until the air humidityreturns to normal.

At high humidity, e.g. after baths and showers, ventilation will be stepped up until the humidity level inthe home returns to normal.

General informationUnit type

Product descriptionComfort 200 Top is a ventilation unit with heat recovery. The unit is designed for air flows up to 308m3/h at 100 Pa external duct pressure.

The unit draws the humid, vitiated air out of the dwelling via the bathroom, WC, kitchen and utility roomand introduces fresh outdoor air into habitable rooms such as living room, bedrooms and office. Thecold outdoor air is heated up in the heat exchanger by the warm exhaust air.

Comfort 200 Top is supplied as standard with a G4 filter in the outdoor air and extract air ducts. If it iswished to filter the outdoor air for pollen, an F7 filter can be purchased as an accessory and mountedsubsequent.

Operation and maintenanceMaintenanceNilan’s ventilation units last for many years, but to get the best out of them whilst avoidingunnecessary electricity consumption, correct maintenance is important.

The following parts require regular maintenance:• Water trap• Filters

Water trapThe water trap may dry out and thus prevent water escaping from the condensate tray, as air will blowinto the unit. Condensate will accumulate in the condensate tray and at some point the water willoverflow, possibly causing damage to the surface below the unit.

The water trap should therefore be checked regularly and filled with water, especially in the summer,where the risk of drying out is highest.

Filter replacementThe filters are intended to protect the fans and heat exchanger from being covered with dust and dirt.

To obtain good operation mode it is important to change the filters when needed. The time controlledfilter alarm is in Nilans control system set for filter change as a factory default setting at 90 days. Thiscan be changed to 180 or 360 days when required.

If the filters are not changed regularly, ventilation is reduced at the expense of the indoor climate andaffects the built-in humidity control system of the unit.

Illustration of filter change

1. The unit must be turned off at the control panel beforeopening the door

2. The suitcase fittings are loosened and the upper door isremoved

3. Remove the two filters from the unit 4. It is a good idea to vacuum the filter chamber toremove any dirt which has collected there

5. Remove the filter pad from the filter frame 6. Place the new filter pad with its smooth side down inthe filter frame

7. Carefully fix the filter pad in place in the filter frame,pushing it well out into the sides. Replace the filter in theunit with the filter pad facing upwards

8. Reset the alarm:

1. Turn the fan speed knob as follows: → 0 → 4 → 0

2. Turn the knob to the desired fan speed

8

Heat exchangerThe heat exchanger should be serviced every two years or so to remove dirt and dust, therebyensuring unimpeded air flow. A blocked heat exchanger will cause the power consumption to go up.

ATTENTIONTurn off the unit at the mains socket before opening the front doors

• The suitcase fittings (1) are loosened and the upper door is removed• Release the 4 screws in the lower front door (2) with a screwdriver and lift the door out• Pull the sensor (3) out of the heat exchanger (Left model)• Carefully pull the heat exchanger (4) out of the unit• Place the heat exchanger in a shower compartment and spray it with hot water• If necessary, wipe down the inside of the unit with a damp cloth• Allow the heat exchanger to drain well before refitting it in the unit• The unit must then run at its highest fan speed for about 15 min.
