PRODUCT DATA Ventilation & passive heat recovery Domestic Passive Ventilation ^ OUTSTANDING INDOOR CLIMATE

Comfort 450 Product description Comfort 450 is an energy-efficient ventilation system with heat recovery for homes with a ventilation requirement of up to 450 m3/h. Comfort 450 can be used in single-family homes, apartments and smaller office areas in commercial premises, where easy installation is required and where an optimum indoor climate is a priority. Comfort 450 includes an integrated CTS 602 control and operating panel, G4 filters, high performance counterflow heat exchanger, bypass damper and efficient EC fans as standard. The fans supply a constant air flow and can be adjusted in...

Planning data Comfort 450 Temperature efficiency Temperature efficiency for systems with counterflow heat exchanger according to EN 308 (dry). Temperature efficiency EN 308: t = (tsupply air-tfresh air)/(textract air-tfresh air) Sound data Sound output level (LWA) Octave band Hz Sound data are for qV = 300 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. Capacity of...

Capacity – Heating element (accessory) Electrical heating surface The electrical heating surface is fitted in the air inlet duct at a distance of min. 2 x duct diameter from the system’s fresh air inlet connecting pipe (normally min. 400 mm) and connected to the CTS 602 control panel and 230 V supply. The electrical heating surface can supply up to 0.9 kW of heat. Water heating element for internal fitting The water heating element is designed to be built into the system and must be connected to the primary heating supply and the CTS 602 control. The water heating element includes copper...

Accessories CO2 sensor With a CO2 sensor installed, the ventilation speed can be pre-programmed with CTS 602 to run at higher ventilation steps when CO2 reaches high level in the extract air. CO2 level is programmable. Water heating element incl. regulation The supply air temperature can always be raised to the required level using a water heating element. The water heating element is designed to be built into the unit and must be connected to the primary heating supply. Supplied with two-way adjustment valve, temperature sensor and frost thermostat. Electrical heating surface incl....

Transport and storage Comfort 450 comes in factory packaging that protects it during transport and storage. Comfort 450 must be stored in a dry place in its original packaging until installation. The packaging should only be removed immediately prior to installation. Installation conditions During installation, future service and maintenance should be taken into account. We recommend a minimum gap in front of and behind the unit of 60 cm. Min. 60 cm The unit must be installed level for the sake of the condensate drain. The condensate drain requires clearance of min. 12.5 cm under the drain...
