VPL 15 Top M2

VPL 15 Top M2 is a ventilation unit with heat recovery for single-family dwellings, small offices and business premises. It differs from an ordinary ventilation unit by being equipped with a heat pump rather than the usual counterflow heat exchanger. We call this active heat recovery. With a heat pump you achieve a higher level of heat recovery, and the unit is therefore also used as heating source in low energy houses.

VPL 15 Top M2 has a reversible cooling circuit, which means that it can heat the supply air in the winter and cool the supply air in the summer. However, the cooling function is not comparable with that of an air conditioning unit. When the supply air is cooled, the air will condense. This results in a reduced level of air humidity indoors during the summer, 
which makes it easier to cope with high indoor temperatures. We therefore call it “Comfort cooling”. 
 

Airflow (see planning data for SEL/SFP values)

Min : 50 m3/h
Max : 400 m3/h

Nilan App - Control the ventilation and heat pump directly from the mobile phone

Nilan has developed an App with great features where the user can control the ventilation and heat pump directly from the mobile phone. The App is intuitive, easy and safe to use, and allows the user to e.g. set the room temperature. More ventilation units can be connected using the same App to control the indoor climate in e.g. both the dwelling and the holiday home. More users can be connected the same App.

When purchasing a Nilan gateway, the user can access the unit via the Nilan App.

According to EN14511, extract air = 21°C.

Dotted curve: Without FU15 heatpipe
Fixed curve: With FU15 heatpipe

Heat effect (supply air)

Heat effect Qc [W] as a function of qv [m3/h] and fresh air temperature [°C]. 

According to EN 14511, extract air = 21 °C 

Dotted curve: Without FU15 heatpipe
Fixed curve: With FU15 heatpipe
Purple curve: Compressor power

Supply air temperature (heating)

Supply air temperature [°C] as a function of fresh air temperature [°C] and volume flow qv [m3/h] balanced flow. 

Extract air temperature = 21 [°C],  45 RH [%] 


X-axis: Outdoor air temperature
Y-axis: Supply air temperature

Dotted curve: Without FU15 heatpipe
Fixed curve: With FU15 heatpipe

Supply air temperature (cooling) 

Supply air temperature [°C] as a function of fresh air temperature [°C] and volume flow qv [m3/h] balanced flow.

Extract air temperature = 24°C

Sound data

Sound data for qV = 210 m3/h and Pt, ext = 100 Pa according to EN 9614-2 for surfaces and EN 5136 for ducts.

Sound output level LWA drops with falling air volume and falling back pressure.

Sound output level LpA at a given distance will depend on acoustic conditions in the place of installation.

The CTS602 control system is an advanced control system with many settings options. The control system is supplied with factory default settings that can be adapted to the operational requirements in order to achieve best possible operation and utilisation of the unit.

The HMI Touch panel provides an overview of the current operation of the unit, and the structure of its menu makes it easy to navigate for both user and installer. There is an option for selecting between 2 front page images for the main screen.

External communication
The CTS602i control unit communicates by default with Modbus RTU RS485 communication. A CTS system using this form of communication can easily be connected to the unit.

Functions overview   +Standard
-Accessories
Alarms Description of errors indicated with alarms. Alarm log displaying the latest 16 alarms. +
Joint alarm The CTS602 control system has an output signal that is activated in the case of an alarm. It can be connected to, for example, external automation.  
Filter monitor Filter alarm with timer that can be set to 30/90/180/360 days. +
Data display An overview of the current operation with regards to temperatures, fan speed level etc. +
Week program The CTS602 control system has 3 week programs that can be set individually (the default setting is “off”). +
Humidity control system Enables a higher or lower degree of ventilation at a high/low level of humidity. +
Air quality Enables you to adjust the degree of ventilation depending on the CO2 level in the air. -

ATTENTION! When positioning the unit, you should always consider future services and maintenance. It is recommended that you leave a minimum of 60 cm of clear space in front of the unit.

It must be easy to replace filters and it must be possible to replace, for instance, fans and other components.

ATTENTION! The unit must be level to enable proper drainage from the condensate tray.

The unit makes little noise and produces only weak vibrations, but you should still take into account potential vibrations that can spread from the unit to individual building components. In order to separate the unit from its foundation, it is therefore recommended that you install vibration absorbers under the unit. There should be approx. 10 mm distance to other building components and to permanent fixtures.

Condensate drain

ATTENTION! You MUST install a water trap in connection with the condensate drain to ensure that condensate water can drain away. If you set up the unit outside the climate screen, it is important to use a heating cable to prevent the condensate drain from icing up. Frost protection of the unit is the installer's responsibility.
