FEATURES

• Flow control for constant flow via pressure sensors

• Post heating, post cooling

• 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

• Frost protection (pre-heater, unbalanced)

• Setup/installation/production settings via RF possible

• Ramses 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.

• More powerful processor for future releases

• USB connector
  - direct connection with servicetool on PC
  - possibility to use USB in factory

• Prepared RF encryption

• Upgradable via USB or RF

• Manual bypass control

• Startup sequence

• Torin fans supported (VMD-02RPS78 only)

APPLICATION

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) which will be controlled based on the software application of the PCB.

Options

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
possible.

NEW FEATURES

• Constant volume

• Faster updates to the cloud

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

• EBM Scroll fan support (VMD-02RMS37 only)

• Balanced frost protection

• Support for our motion detection devices (PIR)

​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.
