Do You Know What Your Ventilation System Is Doing? - December 2014

Titon's auralite® remote status indicator meets the NHBC guidelines regarding visual indicators for maintenance, servicing and operation being visible and not obscured from view, while informing users exactly what the MVHR system is doing.

auralite® is compatible with most Titon HRV Q Plus units and is a low voltage, hardwired status indicator, which is sited remotely from the unit. Fitting onto a standard UK patress box, it features six LEDs, each indicating a different mode as follows:

  1. Normal - this illustrates the system is running at continuous speed, or at setback speed if the light is flashing.
  2. Frost - lit when automatic frost protection mode is activated.
  3. Filter - lights up when the unit’s filters require changing.
  4. Boost - this LED is lit when the system is running in boost speed; if the light is flashing, then boost alert* is active.
  5. Summer - the unit is in Summer Bypass mode, designed to operate during hot periods where fresh air can be vented straight into a property without being preheated by the extracted stale air.
  6. Fault - indicating a fault with the system and the installer should be contacted.

*Boost alert is a timer designed to prevent the MVHR unit being inadvertently left in Boost for long periods of time. When the MVHR is switched into Boost, the timer is started and, after two hours, the alert will be activated. This is indicated by the LED flashing. Once Boost alert has been activated, the overrun timer is disabled, ensuring the unit will return to continuous speed once the switch holding the unit in Boost is released.

It is important that end users know exactly what their MVHR system is doing, what mode it is operating in and if there are any problems with it. auralite® provides a simple and discreet means of monitoring the running status of our HRV Q Plus units, which will also alert users in the rare instances when there is a fault.

Titon's range of whole house MVHR units has been developed in-house and manufactured at the company's UK factory. All Titon MVHR units are rigorously – and individually – tested under strict conditions to ensure they perform to a high standard. The current test method for MVHR in the UK is based on the European Standard BS EN 13141-6:2004 (to define the duct configurations) and 13141-7:2004, which covers the testing of heat recovery ventilation devices.

Some of Titon's MVHR units are even tested according to standards recognised throughout Europe – including important elements of Passivhaus – for strict test criteria and commitment to quality. All Titon products also offer unique benefits throughout the supply chain, being highly efficient to specify, supply, fit and operate.
