Comfort 300LR

Nilan Comfort 300LR is a ventilation unit that is typically used in single-family dwellings and terraced houses.

The unit is often installed in an unused loft so it does not take up space in the utility room. Placing it in the loft also means that it is easy to block potential noise from the unit so it does not enter the dwelling. 
 
Comfort 300LR creates a good indoor climate in the dwelling. The unit also ensures limited heat loss due to its highly efficient counterflow heat exchanger. It has therefore been given the high energy efficiency rating A. 
 

Airflow (see planning data for SEL/SFP values)

Min : 100 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.

Capacity

Capacity of standard unit as a function of qv and Pt ext

SEL values according to EN 13141-7 are for standard units with ISO Coarse >75% (G4) filters and without heating element. 

SEL values comprise the unit´s total power comsumption excl. control.  

Attention! The SEL values are measured and stated as a total value for both fans.

Temperature efficiency

Temperature efficiency for units with counterflow heat exchanger according to EN13141-7.

Sound data

Sound data for qv = 200 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.

CTS400 is a simple and intuitive control panel with a complex control system that contains many useful functions. On the control panel you can set the fan speed level, turn the unit on and off and see potential alarms.

When installed in rental properties, hotels etc., you can lock the panel so tenants cannot turn off the unit and/or alter the fan speed level.

The many functions of the control system enable you to connect, for instance, after-heating elements and a CO2 or VOC sensor. The control system includes, as standard, user selection programs, an intelligent humidity control system and an integral fire automation system.  

CTS400 has open Modbus communication that enables connection to external CTS systems.

The Modbus connection can also be connected to a Nilan gateway cloud solution that allows you to control and monitor the unit via a smartphone App solution.

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.

External communication
The CTS602 control system has an open Modbus RS485 protocol that can be used for communication via external CTS systems.

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.
