Under sill units for vertical installation on an external wall
Please note: The vertical decentralised ventilation unit variant described is equipped with an individual room control located in the unit for self-sufficient room operation. The supplied controllers contain the parameters of the standard control for operation according to our control description.
FSL-V-ZAB/SEK-HE with automatic secondary air changeover function - master unit
TROX FSL-V-ZAB/SEK-HE vertical decentralised ventilation unit with supply and extract air function and switchover option to secondary air operation (depending on air quality), WRG as well as heating and cooling function for installation on on-site facade construction:
- Casing made of galvanised sheet steel, cover and sheet metal connections with deep-drawn threads and stainless steel cross-head screws, internal ducts sealed and lined as required, internal cable penetrations sealed, exposed surface powder-coated (RAL 9005, jet black)
- For fastening the unit on site:
- On the top of the unit: L-bracket with slotted holes
- In the lower part of the unit: oblong holes below the heat exchanger
- Opening on the room side in the upper area for the extract air and secondary air intake, without sealing tape, sealing to the sill panelling by means of closed-pored sealing tape to prevent air short-circuits (sealing tape not included in TROX scope of delivery) is required
- Sound- and heat-insulating lining on suction and discharge side made of mineral wool faced with glass fibre scrim (material classification A, non-combustible according to DIN 4102, T1), erosion resistant up to air velocities of 20 m/s, or closed cell insulation material
- The unit meets the hygiene requirements of VDI 6022
- Levelling feet, +40 mm
- Connection to the on-site fresh air and exhaust air openings of the façade by means of a circumferential, closed-pore sealing tape (40 mm wide, 10 mm thick) on the rear side of the unit. The intake and discharge resistance of the on-site construction should not exceed 20 Pa at nominal volume flow. The weather protection must be provided on the façade side and serves to protect the unit (weather protection not included in TROX scope of delivery)
- Use of 2 energy-saving EC centrifugal blowers, supply and extract air fan classified in category SFP 0 (< 300 W/(m³/s)) according to DIN EN 16798-3:2017-11
- Suitable for 4 speed levels (e.g. 60, 90, 120 and 150 m³/h), control via unit-internal individual room control, volume flow rate level correction by adjusting the control voltage subsequently possible
- Meets the requirements of EU Regulation 1253/2014 (ErP Directive)
- Low sound power level in supply/extract air mode and secondary air mode
- Integrated recuperative, cross-counterflow heat recovery unit, heat recovery efficiency > 82 %, including condensate drip tray and discharge into the heat exchanger condensate drip tray. Accessibility for maintenance purposes via separate service cover possible without removing the unit cover
- With electric motor bypass, which bypasses the air volume flow to the WRG, drive 24 V (continuous), 0 - 100 %, control via unit-internal single room control
- Motorised shut-off dampers in fresh air and exhaust air areas, normally closed in inactive state via energy storage, 230 V drive, open-close, control via unit-internal individual room control system
- Automatic switching to secondary air mode (only with an air quality sensor) if the room air quality (measured with the integral CO2sensor, for example) is within the defined limits. The outdoor air damper closes, the self-powered secondary air damper opens and the extract air fan is switched off.
- Integral electrical components are completely wired with FSL-CONTROL III, control components are integrated. Cable for connection (connection by others) to the power supply (L, N, PE), with wire end ferrules, approx. 1 m routed out of the casing:
- Supply voltage (230 V): 3 wires, 3 × 1.5 mm² (L, N, PE)
- Connection option for bus communication (optional), connection of room control unit etc. after opening the customer area of the control. As a transfer point to the on-site trade measurement/control/regulation:
- Rail mount terminals type Wago 260 for the connection (by others) of
- Digital inputs DI
- Digital outputs DO
- Master-slave connection RS485
- Optional connection to building automation (GA) via RS485 (Modbus/BACnet)
- Room control panel
- RJ45 socket as service access to the user interface
- Optional connection to GA via Ethernet (Modbus/BACnet)
- The following sensors are arranged in the unit to control the individual room control (the actual room temperature is recorded on the room control unit or (optionally) transmitted via the GA):
- Indoor air quality sensor CO2
- Supply air temperature measurement downstream of the heat exchanger
- Outdoor air temperature measurement in the outdoor air intake
- 2- or 4-pipe aluminium copper tube heat exchanger for air heating or air cooling, matched to project-specific data, easily removable for cleaning (depends on the connection to the main pipe - by others, not included in the TROX supply package), drainage and venting option per heating/cooling circuit, arrangement on the room side on the right. We recommend flexible hoses (not part of the supply package) to connect the unit to the existing pipe network (by others) as they simplify removal of the heat exchanger for cleaning
- Transfer points are the manually pre-assembled control components
- Valves in the return: transfer with G ½" external thread, flat seal
- Lockshields in the flow: transfer with G ½" external thread, flat seal
- Easy-to-clean condensate pan made of galvanised sheet steel, powder-coated RAL 9005, with condensate drain Ø 12 × 1 [mm]
- Outdoor air filter as Mini Pleat filter, class ePM1 (fine dust filter):
- Filter class to ISO 16890: ISO ePM1 65%
- Eurovent-certified
- ePM1 filter media made of high-quality, wet-strength fibreglass paper are laid in tight pleats, the spacers are made of thermoplastic hot-melt adhesive and ensure that the pleats are evenly spaced (4 mm) from each other
- The frame is made from moisture-resistant non-woven fibre with brackets (for pulling it out) and must not reduce the flow cross-section (filter size = flow cross-section)
- Filter area ≥ 1.8 m²
- Extract air filter (coarse dust filter) as flat filter medium, filter class according to ISO16890: ISO coarse 50 %
- Easy inspection of the filters and the heat recovery unit due to the compact arrangement of the components behind the service cover. The service lid can be opened without tools via user-friendly quarter-turn fasteners. Accessibility must not be restricted by the on-site parapet cladding
- Closed cell sealing tapes for sealing and adaptation to the outer casing provided by others (not included in the TROX supply package)
- The sill cladding provided by the customer shall have perforations in areas of the heat exchanger to be specified for the introduction of supply air into the room and shall not restrict maintenance work or unit assembly/disassembly on the front side of the unit. An opening for extract air intake must also be arranged in the upper area of the cladding
- The clear distance between the front edge of the unit and the inner edge of the parapet cladding should not be less than approx. 30 mm
- The front of the device must be completely accessible after disassembly of the outer casing
