Comfort 250L/Comfort 250R

The Comfort 250L/Comfort 250R is an energy efficient ventilation unit, offering heat recovery for homes and smaller commercial buildings with ventilation requirements of up to 250 m3/h. Comfort 250 is only available for project sales.

Comfort 250L/R is equipped with a unique boost function intended for cooker hood operation. By activating user selection, you get the option of an extra 50 m3/h to ensure more suction in the cooker hood. The Comfort 250L/R can via the boost function provide 300 m3/h at 200 Pa external pressure drop.

The unit is often installed in an unused attic so it does not take up space in the utility room. This also means that it is easy to block potential noise from the unit so it does not enter the dwelling. The special design with all four connectors on the same side, in many cases makes the unit easier to place in the attic. The large filter door makes filter change easy and without any use of tools.

Comfort 250 creates a good indoor climate in the dwelling and ensures limited heat loss due to its highly efficient counterflow heat exchanger. Comfort 250L is the left version and Comfort 250R is the right version.

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 represent the unit’s total power comsumption for both ventilator, excl. control. Testet according to EN13141-7

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

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. 

Functions overview   +Standard
- Accessories
Filter monitor Filter alarm with timer (the default setting is 90 days). You can set this to anything between 1 - 360 days. -
Bypass The air will bypass the heat exchanger if heat recovery is not required. +
Humidity control system Enables a higher or lower fan speed level at a high/low level of humidity. +
Summer/winter mode Setting for when the unit is to operate in summer or winter mode respectively. +
Stop at low room temperature Stops ventilation at low room temperature if, for instance, the heat supply fails. +
De-icing Automatic function that de-ices the exchanger based on temperature. +
Temperature control Controls the bypass and potential after-heating elements in accordance with the selected room temperature. +

Locking the control panel You can lock the control panel so it cannot be turned off and/or the fan speed level cannot be altered. +

 

 

ATTENTION! When positioning the unit, you should always consider future services and maintenance. An open space of minimum 60 cm in front of the unit is recommended.

It must be easy to change filters, and it must, for instance, be possible to remove the heat exchanger, and to replace fans or other components.

ATTENTION! The cabinet tilts (is not horizontal), in that way the condensation water runs off more easily. It is important that the surface on which the unit stands is level, so the unit has the correct tilt.
