Description
FEATURES
Air handling units for efficient supply and exhaust ventilation in flats, houses, cottages and other buildings.Heat and humidity recovery minimizes ventilation heat losses during cold season and reduce air conditioner load during hot season.Controllable air exchange for creating the best suitable indoor microclimate.Compatible with round Ø125, 160, 200 mm air ducts.  
DESIGN FANS
The casing made of high-quality polymer coated steel, internally filled with a heat- and sound-insulated layer of mineral wool.The spigots are located at the top of the unit, and are rubber sealed for airtight connection to the air ducts.Depending on model, the units are equipped with either hinged sevice panel for easy maintenance operations or separate access for quick filter replacement (KOMFORT EC S(B)200(-E), KOMFORT EC S(B)250(-E)).
High-efficient external rotor EC motors and centrifugal impellers are used for air supply and exhaust.EC motors have the best power consumption to air flow ratio and meet the latest demands concerning energy saving and high-efficient ventilation.EC motors are featured with high performance, low noise level and totally controllable speed range.Dynamically balanced impellers.
AIR FILTRATION
The built-in F7 supply filter and G4 extract filter provide efficient air filtration.KOMFORT EC S(B)200(-E) units are equipped with G3 supply and extract filters.
KOMFORT EC S(B)250(-E) units are equipped with G4 and F7 filters for supply and G4 filters for extract.  
 
HEAT RECOVERY CONTROL AND AUTOMATION
The KOMFORT EC S(B) units have a counter-flow polystyrene heat exchanger that recovers heat.
The KOMFORT EC S(B) -E units have a counter-flow enthalpy membrane heat exchanger that recovers heat and humidity.Due to humidity recovery the enthalpy heat exchanger produces no condensate.The air flows are fully separated within the heat exchangers. Odours and contaminants contained in the extract air are not transferred to the supply air flow.Heat recovery is based on heat and/or humidity transfer through the plates of the heat exchanger. In the cold season supply air is heated in the heat exchanger by transferring the heat energy of warm and humid extract air to the cold fresh air. Heat recovery minimizes heat losses, which reduces the cost of space heating.In summer the heat exchanger performs reverse and intake air is cooled in the heat exchanger by the cooled extract air. This reduces load on air conditioners and saves electricity.

FROST PROTECTION
The electronic frost protection system is used to prevent the heat exchanger freezing in cold seasons. Depending on the model either supply fan stop and/or electrical preheating freezing protection is available.
KOMFORT EC S S11 / KOMFORT EC SB S11 units incorporate an integrated control system with the S11 wall-mounted control panel with an LCD display.
KOMFORT EC S S14 / KOMFORT EC SB S14 units incorporate an integrated control system with the S14 wall-mounted control panel with a LED indication. The units are equipped with the Type B USB Connector for advanced options setting in a special software. The standard delivery set includes a 10 m cable for connection of the unit and the control panel.
S11 automation functions:
  • Activating/deactivating the unit.
  • Setting required supply and extract fan speed for the unit air flow control. Each speed is individually adjusted during set-up.
  • Automatic bypass damper opening / closing for summer ventilation.
  • Setting and maintaining room or duct air temperature.
  • Timer turning on/off and timer operation adjustment.
  • Setting day- and week-scheduled operation of the unit.
  • Operation control on feedback from FS1 duct humidity sensor (available separately) or from the humidity sensor in the control panel.
  • Filter clogging indication by motor meter.
  • System shutdown on signal from a fire alarm panel.
  • Controlling supply and exhaust air dampers (available separately).
  • Alarm indication with an error code indication.
  • Cooler control (to be ordered separately). 
S14 automation functions:
  • Activating/deactivating the unit.
  • Air flow control (selecting low, medium or high speed).
  • Bypass damper opening/closing for summer ventilation.
  • Alarm indication.
  • Filter maintenance indication.
Extra functions of the S14 automation with the installed software:
  • Fan speed control from 0 to 100 %. Each speed is individually adjusted for the supply and the exhaust fans.
  • Operation control on feedback from FS2 duct humidity sensor or any other optionally connected sensor as CO2 sensor, IAQ sensor, etc. (not included in the delivery set).
  • Unit operation setting according to external control unit (available as a specially ordered accessory).
  • Temperature setting for freeze protection system activation.
  • Control and operation adjustment of the filter maintenance timer.
  • Error code indication.
  • Remote control unit, bypass and humidity control.
  • Software version upgrading. 
BYPASS
The KOMFORT EC SB and KOMFORT EC SB...-E models are equipped with a 100 % bypass which can be opened if there is a need to cool down the ventilated area with cool intake air.
MOUNTING
The units are designed for wall and floor mounting.The access for unit and filter maintenance is available from the front panel.During mounting stage the front and the back panels can be reversed providing either left-handed or right-handed unit mounting.
