Safety

Power supply

CAUTION

Always disconnect mains electricity to the unit if a fault occurs which cannot be rectified via the

control panel.

CAUTION

If a fault occurs on the electricity-conducting elements of the unit, always contact an

authorised electrical installer to rectify the fault.

CAUTION

Always 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 be

disposed of with household refuse. Take them to your local recycling centre.

Quick guide

Control panel

Functions

The CTS150 control panel provides the following functions:

1. Setting fan speeds: 0 (off) - 1 - 2 - 3 - 4

2. Green diode: On when the unit is running

3. Setting low humidity: Can be set between 15 and 45%

4. Red diode: Flashes in the event of an alarm

Alarms

If 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

2. T4 temperature sensor missing No

3. T8 temperature sensor missing No

4. temperature sensor missing No

5. De-icing alarm No

6. Filter alarm No

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

triggered

• To re-activate the de-icing alarm, disconnect electricity and restart the unit

• The unit shuts down when a critical alarm is active

Reset alarm:

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

2. Turn the selector to the fan speed required

Fan speed

Recommended 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 asked

to 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 2

corresponds 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 fan

speed 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 the

ventilation system).

Humidity control

Humidity 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 gets

below 30%. You can set low ventilation at low humidity in the range of 15 to 45%. We recommend a

setting of 30%.

The integrated humidity control system will control the ventilation level automatically on demand. The

system 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 to

an low level. When air humidity indoors is too low, the ventilation level is reduced until the air humidity

returns to normal.

At high humidity, e.g. after baths and showers, ventilation will be stepped up until the humidity level in

the home returns to normal.

General information

Unit type

Product description

Comfort 200 Top is a ventilation unit with heat recovery. The unit is designed for air flows up to 308

m3/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 room

and introduces fresh outdoor air into habitable rooms such as living room, bedrooms and office. The

cold 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 is

wished to filter the outdoor air for pollen, an F7 filter can be purchased as an accessory and mounted

subsequent.

1. Duct connections

2. Electrical connections

3. Automatic control system

4. Bypass-damper

5. Extract air filter G4 (left model)

6. Outdoor air filter G4 (F7 filter is fitted here) (left model)

7. Supply air fan (inlet air)

8. Extract air fan (outlet air)

9. Counterflow heat exchanger

10. Condensate drain

Operation and maintenance

Maintenance

Nilan’s ventilation units last for many years, but to get the best out of them whilst avoiding

unnecessary electricity consumption, correct maintenance is important.

The following parts require regular maintenance:

• Water trap

• Filters

Water trap

The water trap may dry out and thus prevent water escaping from the condensate tray, as air will blow

into the unit. Condensate will accumulate in the condensate tray and at some point the water will

overflow, 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 replacement

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

Always change the filters before they become blocked to ensure maximum efficiency. The Nilan G4

filters should be replaced every 3 months for normal use. We recommend changing them for the first

time after 30 days for new buildings, as they can quickly become blocked by building dust.

If the filters are not changed regularly, ventilation is reduced at the expense of the indoor climate and

the unit will use more electricity than necessary, and can be damaged.

Illustration of filter change

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

opening the door

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

removed

3. Remove the two filters from the unit 4. It is a good idea to vacuum the filter chamber to

remove 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 in

the 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 the

unit 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

Heat exchanger

The heat exchanger should be serviced every two years or so to remove dirt and dust, thereby

ensuring unimpeded air flow. A blocked heat exchanger will cause the power consumption to go up.

ATTENTION

Turn 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.
