Explanation of HRV Features

  • Normal - Continuously running extract and supply, set on install in accordance with the requirements of the applicable Regulations.
  • Boost - Increases ventilation rates on demand, set on install in accordance with the requirements of the applicable Regulations.
  • Setback - Provides a reduced ventilation rate for dwellings that are unoccupied for a long period.
  • SUMMERboost® - Only available with ABS option, increases both the supply and extract to full speed when the automatic bypass engages.
  • Summer Bypass - Automatically controlled, bypasses the heat exchanger when indoor/outdoor temperature conditions make heat exchange undesirable.
  • Duct Heater Control - Used for the automatic control of in-line duct heaters to help prevent heat exchanger freezing.
  • Summer Mode - Turns off the supply air on demand or via a remote thermostat. (Additional controllable background ventilation may be required).

How do I purchase replacement filters?

Replacement filters can be bought from our online shop, TitonDirect.

Titon HRV Q Plus filters are available in two grades G3 and G4. Your HRV Q Plus unit comes with G3 filters as standard (HRV10 Q Plus units have G4 filters as standard). G4 filters are a slightly higher grade of filter, but add extra resistance, which in turn may make the unit run at an increased level generating slightly more noise and power consumption.

Filter may be supplied with either metal or plastic frames both are fully compatible with the units.

Please refer to this table to identify which filter is suitable for your unit.

My MVHR system doesn't work

MVHR systems running quietly at low levels are often thought not to be working so always check for airflow by listening and feeling close to the airvalves. Also, check the MVHR unit is switched on and that filters are not blocked. Further advice can be found in your product handbook.

If you have just purchased a new home then report your issue to your Builder or the Installer.

If you need expert help then please visit our page of preferred suppliers and installers.

My MVHR system is noisy

Check that the unit has not been left in boost mode or is not in automatic humidity boost or SUMMERboost mode.

Check that filters are not blocked. Further advice can be found in your product handbook.

If you are unable to resolve the problem and you have just purchased a new home or recently had the system installed then report your issue to your Builder or the Installer.

If you are not covered by the builder/installer warranty and need to find expert help then please visit our page of preferred suppliers and installers.

My MVHR system needs adjusting

Once installed and commissioned by the engineer, MVHR systems do not need adjustment. MVHR systems are set to run continuously at low level and boost on demand usually via a switch located in kitchens and bathrooms. The rates at which they move air in normal and boost modes are set in accordance with building regulations by the commissioning engineer.

Some systems are fitted with more advanced controllers such as the Titon Aurastat, allow the user to change other parameter and choose additional functions. To find your controller handbook select your unit from this list and download the relevant document.

If you think the system is moving too much or too little air then it may be due to an automatic function such as Frost Protection, Humidity Boost or SummerBoost.

If you are unable to resolve the problem and you have just purchased a new home or recently had the system installed then report your issue to your Builder or the Installer.

If you are not covered by the builder/installer warranty and need to find expert help then please visit our page of preferred suppliers and installers.

I want to turn off my MVHR system

MVHR systems are designed to operate continuously even when a building is not occupied as your home is full of potentially harmful things if it is not ventilated properly. If you turn off your MVHR unit you are putting your health at risk. Read more about Indoor Air Quality and its potential effects.
