short description

Centralised ventilation unit with very effective heat recovery through cross-counterflow exchanger, EC motors with constant volumetric flow regulation, supply and exhaust air on the left, 4 x DN 125, DIBT approval, 70 - 165 m³/h, KNX connection possible

Product description

Features

  • Automatic constant volumetric flow regulation for equal air quantities.
  • Special energy savings due to the DC motor.
  • Powder-coated plate housing in sandwich construction, with integrated heat insulation.
  • Colour: light grey.
  • Integrated filter system with coarse filter (G4) in the outside air and in the exhaust air. Filter change is possible without tools.
  • 2 DN 125 duct connections each with rubber lip seals on side walls of unit. For directly connecting up tubular sound absorbers.
  • Controlled through control unit RLS 2 F in the living room.
  • Control unit for switching ventilation levels, timer and filter monitoring.
  • Control unit not included in scope of delivery.
  • DIBT approval.
  • Connection to KNX systems possible.

Heat exchanger

  • Counterflow heat exchanger made of aluminium.
  • The heat exchanger can be easily removed and cleaned with water.

Frost protection

  • Frost protection by switching off the supply air fans.
  • The frost protection feature switches the supply air fan off when the heat exchanger starts to freeze up.
  • Recommendation: Combine heat recovery units with a brine earth heat exchanger.

Energy-efficient fans

  • 2 centrifugal DC fans, one fan each for supply air and exhaust air.
  • 3 ventilation levels can be set:
    • 1 = Reduced ventilation: 70, 85, 95, 105 m3/h
    • 2 = Nominal ventilation: 85, 100, 120, 135 m3/h
    • 3 = Intensive ventilation: 120, 135, 150, 165 m3/h
    • Factory setting: 70/100/135 m3/h.

Mounting instructions

  • Mounting on the wall or a pedestal is required to ensure access to the condensation connection.
  • The front plate can be hinged open after loosening the 2 quick-release clips.
  • Decouple the housing with impact sound plates for sound insulation.

Condensation drain

  • Condensation is drained out at the bottom of the unit. Condensation drainage (3/4" external thread) for connection to a 1/2" hose.
