Prometeo HR400

Controlled ventilation of living space (KWL) is becoming increasingly important in times of rapidly rising energy costs as a means of reducing heating costs. The precious heat is extracted from the used exhaust air from the living spaces by means of heat exchangers and transferred to the fresh air supplied from outside. At the same time, in today's increasingly dense building envelopes, this ensures the necessary exchange of stale and humid air to prevent health hazards for the occupants and moisture damage to the building.


The deviceät can be operated lying or standing.	Prometeo features a fully automatic summer bypass.	A wireless bidirectional remote control is included.

Design - Sleek, modern industrial design. Housing made of PPE (polyfoam). Installation horizontally with mounting fixtures or wall-mounted with enclosed bracket.
Heat exchanger- highly efficient according to the counterflow principle made of polyethylene with a thermal efficiency of up to 92%.
Motors - two powerful centrifugal fans with high-efficiency EC DC motors promote an air performance of up to 380 m³/h.
Sensors - Adjustable CO2, humidity and temperature sensors are built into the unit to optimally control the unit fully automatically according to the current room conditions.
Filtered - The supply and exhaust air streams are separated and filtered üvia the built-in F5 filters, which are easily accessible from the outside. The outside air filter can be replaced with an optional F7 class fine dust filter. The filter status is monitored and a due filter change is signaled visually and acoustically on the remote control.
Radio remote control - The device has a bidirectional radio remote control with which all device functions can be controlled. The user has access to the following settings:
→ Manual operation (selection of operating levels 1, 2 or 3).
→ Automatic mode (the operating level is selected automatically by the system according to the values determined by the CO2, humidity and temperature sensors.
→ Summer mode (outside air supply bypassing the heat exchanger).

→ Desired indoor temperature (crucial for switching the summer bypass).
→ Timer (the unit operates for 10, 20 or 30 minutes at the highest level before automatically switching back to level 1.
The remote control shows the following values on the display:
→ Working mode of the system (Manual, Automatic, Summer).
→ Operating level (1, 2 or 3)
→ Timer settings.
→ Average temperature, rel. humidity, CO2 degree.
→ Time and date.
Frost protection - When the temperature and humidity of the indoor and outdoor air streams threaten to freeze the heat exchanger, the frost protection valve öopens fully automatically to correct the condition.
Summer bypass - If the outdoor temperature is equal to or higher than the desired indoor temperature, but lower than the current indoor temperature, the bypass valve öopens automatically and allows direct airflow of the outdoor air bypassing the heat exchanger. Particularly useful in balmy summers.
Soundproofed - The scope of delivery includes a pipe sound attenuator (L=500 mm), which should be installed in the room-side duct for optimum conditions.
Powerful - Only 24 watts of energy consumption at 170 m³/h*.
Accessories - Extensive accessories such as. Supply and exhaust air disc valves, flexible ducts, air distribution boxes, roof hoods, weather louvers, shut-off dampers, door grilles, duct tape, hose clamps and much more are available.
