Product description
Comfort CT150 / CT200 is an energy-efficient ventilation system with heat recovery for homes with a ventilation requirement of up to 200 m3/h. Comfort CT150/ CT200 is particularly suitable for newly built or renovated flats, raraced house and summer cottages where the space is limited.
Comfort CT150 / CT200 is designed for vertical or horizontal mounting, which ensures flexible installation.
Comfort CT150/ CT200is factory tested and ready for use. Installation and commissioning must be performed by an authorized electrician.
OPERATION
Intelligent humidity control
Nilan’s humidity control automatically adapts to the needs of inhabitants or the building itself.
The intelligentCTS602 control unit does not require a set air humidity level (RH) to manage the air exchange. Using the integrated humidity sensor, the control unit calculates the average humidity over the past 24 hours and regulates the air flow accordingly.
Consequently, the unit’s efficiency is based on actual instead of theoretical air humidity levels.
Automatically adapting to air volume requirements saves energy as the number of persons in a home is relevant as to how much humidity is produced.
The unit also adjusts automatically to summer and winter levels.
AUTOMATION CTS150
CTS150 Control
The CTS150 control unit is a simple control unit used to control the CT150 / CT200 system. It offers the user only limited access to settings.
Users can adjust the air volume and humidity levels
The control unit also shows whether the system is working and when an alarm is triggered.
To set and regulate the system, it has to be connected to a PC via a USB flash drive. Download the software from Nilan Net and install. The software can be used not only to set the system, but also to read operating data.
AUTOMATIKCTS602
CTS 602 styring
The CTS602 HMI touch panel is featuring a wide range of functions, e.g., menu-controlled operation, weekly programme settings, filter monitor with timer, fan speed adjustment, summer bypass (free cooling), supply-heating element control, error messages etc.
The CTS602 comes with factory settings, including a default setting which can be customised to operational requirements to achieve optimum operation and utilisation of the system.
There is an option for selecting between 2 front page images for the main screen.
Operating instructions for the CTS 602 can be found in a separate user manual supplied with the unit.
External communication
The CTS602 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.
Nilan units have an open Modbus communication, i.e. not only can the unit be monitored, but its operation can also be set in the same way as it can via the operating panel.
The protocol is by default set up for a Modbus RTU30 address; however, values can be set between 1 and 247.
A Modbus converter allows you to connect one or more units to a computer to monitor and control the unit.
INSTALLATION OPTIONS
Top installation (standard)
Comfort CT150 / CT200 is delivered with two strong installation rails, which can be fastened to the ceiling or wall with suitable raw plugs and screws.
This ensures an easy installation of Comfort CT150 / CT200 because you do not have to support the unit when fastening. All you have to do is installed the two rails and afterwards the unit can easily be glided into place.
OPERATION
Frost protection
All ventilation units with a counterflow heat exchanger Willis up if the outdoor temperature is below freezing for a prolonged period.
The extracted air condenses when it is cooled down during heat recovery. The high temperature efficiency will slowly turn the condensate to ice, which will block up the counterflow heat exchanger unless remedial action is taken.
It should be considered whether the units operation can be protected during a lengthy period of frost or whether it is acceptable to decrease its operation.
In homes which are occupied at night, it would be advisable to protect the unit against frost when the outdoor temperature is coldest by using a pre-heating element. On the other hand, if the ventilation is for an office, it may be acceptable to decrease the operating level at night.
