Comfort 1200

Comfort 1200 is a ventilation unit with heat recovery. It is often used for centralised ventilation of residential buildings and for ventilation of schools, offices and commercial buildings.

The unit is available in both a right-facing and a left-facing model. It is well insulated and you can therefore install it outside the climate screen. If the unit is to be installed outdoors, you can order a top cover to protect the unit from rain and snow. 

All components are carefully selected to maintain the highest level of quality, and they are tested throughout the production process. Once fully built, the units are likewise tested before they leave the factory. The thorough quality control is a reflection of our high standards. Due to these, our products last for many years.

Capacity

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

SFP values according to EN 13141-7 are for standard units with ISO ePM10 >60% (M5) filter in extract air, ISO ePM1 50% (F7) filter in fresh air and no heating element. 

SFP values comprise the unit´s total power comsumption incl. control.

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

Temperature efficiency

Temperature efficiency for unit with counterflow heat exchanger according to EN308 (dry).

Temperature efficiency EN308: ɳ t = (tsupply air-tfresh air)/(textract air-tfresh air)

Sound data

Sound data for qv = 1200 m3/h and Pt ext = 250 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 CTS602i 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 CTS602i control system has an open Modbus RS485 protocol that can be used for communication via external CTS systems.

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. -
Winter low You can prevent a low level of humidity in the dwelling by activating low ventilation at low outdoor temperatures. +
Temperature regulation Enables you to control the operation of the unit in accordance with the room temperature. +
Summer/winter mode You can set the unit to operate in summer or winter mode.  
Language You can choose from more than 10 languages in the control panel. +
User levels The menu in the control panel is divided into 3 user levels: User/Installer/Factory. +
User selection 1 Enables you to override the operating mode via an external potential free signal. +
Electrical after-heating element An electrical after-heating element allows you to control the supply air temperature. In this way the unit can help heat the dwelling. -
Water after-heating element A water after-heating element allows you to control the supply air temperature. In this way the unit can help heat the dwelling. -
Frost protection In order to protect a potential water after-heating element against frost damage, the unit will stop and display an alarm if the temperature in the water after-heating element becomes too low. -
Air exchange Stepless setting of four fan speed levels. The supply air and the extract air can be set individually. +
De-icing Based on temperature, this automatic function de-ices the counterflow heat exchanger if ice has formed within it. +
Room low Safety function that will cause the ventilation unit to stop if the heating system for the dwelling fails. This will prevent the unit from cooling the dwelling even further. +
External heating The ventilation unit can control an external heat supply in accordance with the current room temperature. +
External fire automation system You can connect the ventilation unit to an external fire automation system or to a fire thermostat. This will signal to the unit whether to stop or continue operation. +
Integral fire automation system The ventilation unit is available with an integral fire automation system that can control fire and smoke dampers. -
Pressure sustaining regulator You can install a pressure sustaining regulator on the side of both the extract air and the supply air. -
Delayed start-up You can activate a delayed start-up of the fans if you install, for instance, a shut-off damper. +
Restore settings You can save the current settings and subsequently restore them if, for instance, the user has altered the settings on the unit. You can also reinstall the default settings. +
Manual operation Different functions can be tested manually. +
Energy saving function You can activate a power saving function of the operation. +
Modbus  You can set the Modbus address of the unit. The default setting is 30. +
Data logging It is possible to log the operational data of the unit every 1 - 120 min. Alarms are logged when they occur. +
Control panel You can choose from 2 different images for the main screen. +

You can find further information about all the functions in the Software and Installation instructions for the unit.

 

ATTENTION! When positioning the unit, you should always consider future services and maintenance. It is recommended that you leave a minimum of 90 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.
