Dantherm Attic and Wall Mounted Mechanical Ventilation & Heat Recovery / MVHR Units: RCV Range
Function
The attic and wall mounted mvhr unit ventilates residential homes by extracting the inside humid air, and replacing it with fresh outside air, which has been heated with the heat energy of the extracted air. This reduces energy consumption. When very humid inside air is extracted, the humidity will condensate inside the heat exchanger and be collected by the embedded drip tray. This water is drained from the unit through the enclosed hose and then disposed of in the nearest drainage. ducts connected to the home (supply and extract) are always on the left-hand side of the unit. The condensation drain is located at the rear of the unit.
The air volume can be controlled by:
- Selecting a fixed fan speed from 0-4.
- Demand mode, in which a built in RH sensor continuously adjusts the fan speed depending on any immediate demand, determined by the humidity of the extracted air.
- Week timer program – the fan speed will increase or decrease according to an hourly time schedule, or specific demand.
Mirroring all duct connections
2 set-up in 1 unit, easy change on site.
The air flow direction can be electronically swapped, providing ability to route the connected ducts, either to the right or to the left. This means that the supply air duct connections can be either to the right or to the left hand side of the unit.
Unlike all other residential ventilation units on the market, the RCV attic and wall mounted mvhr unit offers a stunning 48 different ways of connecting ducts to the unit.
24 available combinations for left setups (A) and 24 for right setups(B). Simply choose whichever one is more convenient in terms of installation!
With this flexible unit, you’ll be able to find a fast and cost-efficient way to finalise installation work, even in the trickiest of installation areas.
On the RCV 320 it is possible to connect the supply duct to the bottom if the ducts are to run beneath the floor.

Flexible functionality
All attic and wall mounted mvhr units are equipped with easy-access filter slots behind the upper front cover. The control panel with LED light indicators is located in an opening in the front cover.
The factory-mounted duct seals on the side of the unit can easily be removed using a side cutter and then used to seal off other ducts not to be used.
Cabinet
The RCV insulation is made of expanded polystyrene (EPS) with outer surface is made of 0.8mm Aluzinc sheet metal. This has a high insulation level, and good air tightness, which permits location of the units in spaces with temperatures down to -12°C.
The RCV series complies with European fire safety requirements as specified in EN 13501 class E
The leakage rate of the unit (internal and external) is <2% as specified in EN13141-7 leakage class A1.
Installation
After installation of the unit, ducts and condensate hose, the unit needs to be calibrated to the specific environment. Appropriate initial adjustments are performed with Dantherm PC Tool.
Maintenance
In general, the only regular maintenance required by the RCV residential ventilation units is to check/change the air filters twice a year when the alarm is triggered (flashing LED and acoustic alarm).
The user changes the filter by opening the filter cover, changing the filters and resetting the filter timer on the built-in control panel. Apart from changing the air filters and cleaning the outside of the unit, any other form of service will have to be carried out by qualified personnel.
Local Dantherm partners are always available with support to solve any problem that might arise with the unit. Removing the front cover gives access to all types of service and repair.
