VMD-02RPS66-2 / VMD-02RPS78-2 / VMD-2RMS37-2



• ModBus

• Flow control for constant flow via pressure sensors

• Post heating & cooling (both primarily and secondary

• Configurator tool

• Interaction with app and cloud: “ready for use”

• Multi purpose inputs (e.g. hood/fireplace)

• 2x 230VAC inputs for speed selection

• Bypass via 230VAC or stepper motor 24V unipolar

• Setup/installation/production settings via RF possible

• AICE RF 868 MHz
   - Ideal for renovation and new projects or to add extra
     sensors and user interfaces without the need for
     cables with the device. • USB connector
   - direct connection with service tool on PC
   - possibility to use USB in factory

• Upgradable via USB or RF

• Manual bypass control

• Startup sequence

• Output activated when motors are not running e.g.:
valves are closed when it is cold outside. It can also
control an external device

• Frost protection, multiple strategies

• Support for our motion detection devices (PIR)

• Real time clock

• Multizone support

• Mirroring

• Pre-heating

• Geotherm Heat Exchange

• Constant pressure, supports valves which request a
constant pressure in the ducts. Mostly used in stacked


The Heat Recovery Unit (HRU) ventilation platform
gives you the flexibility to make different solutions for your ventilation systems. For a basic system set up but also for more advanced systems.


The PCB can be used for central residential heat recovery. The platform is set up to make more economic standard systems up to high valued systems. Two fans can be connected via PWM or Modbus (VMD-02RMS37-2) which will be controlled based on the software application of the PCB.

The PCB is prepared to support most of your
requirements. A standard implementation can be
4 temperature sensors, a bypass valve control and
wireless control via sensors, wireless display or manual
controls. The options can be set On or Off in a setting
list. Also default setting can be adjusted by use of the
production tool (separate available). A cable is required
to connect the dp flow sensors to the VMD. For higher
quantities, customization of hardware and software is

VMD-02RPS78-2 Torin PWM fans support
VMD-02RMS37-2 EBM Scroll fan support

Pre-compliance test

Airios offers a valuable service to ensure that HRU systems comply with CE regulations. By conducting thorough assessments and tests, including EMC testing (emissions / immunity) and determining the correct antenna position, Airios helps increase the likelihood of certification by a notified body without the need for costly re-testing. This not only saves time and money but also ensures that HRU systems meet regulatory standards.

Additionally, incorporating Airios products into the design process through our design-in protocol can streamline the integration process and make it easier to use our products within HRU systems.


If you're interested in utilizing Airios' pre-compliance testing service, reaching out to your Airios account manager is the next step.
