The table below lists the models covered by this Product Manual. To find out what features your Titon HRV Q Plus has refer to the part number. The part number can be found on the serial number label fixed to the top and front of the unit.
Controls & Features The HRV Q Plus units are controllable by various volt free switches and sensors. The following describes the controls and features of the HRV Q Plus units and how they are controlled. Refer to the table opposite. Ensure all controls are adequately labelled, indicating their function clearly.
Filter Covers The units are fitted with removable filter covers on the front panel. Auto Setback Speed Setback Speed is used to reduce ventilation rates. Setback Speed is automatically set at the mid point between minimum possible Continuous Speed and the selected Continuous Speed.
Summer Bypass Summer Bypass is designed to operate during hot periods where fresh air can be vented straight into the property without being preheated by the extracted stale air. Summer Bypass operation is automatically controlled. The Summer Bypass mechanism diverts the stale air being extracted from the dwelling around the heat cell so that its heat energy is not transferred to the fresh air being supplied to the property.
Automatic Frost Protection During very cold weather, Automatic Frost Protection will detect temperatures that could form ice inside the unit. It will reduce the supply ventilation rate to prevent ice build up within the heat cell. Automatic Frost Protection reduces the flow rate of cold air, thus allowing the warmer stale air to raise the temperature within the heat cell to such a level that prevents the formation of ice.
Packaging Contents Inspect the unit when taking delivery. Check the unit for damage and that all accessories have been supplied. Each HRV Q Plus unit is supplied with: Mounting Bracket x 2. Safety Bracket x 1. 15mm Condensate Drain Olive & Nut x 1. ...
Installation Fixing Titon recommend the use of guidance given in the Domestic Ventilation Compliance Guide 2010 Edition ISBN-978 1 85946 378 9 and Approved Document Part F 2010 ISBN-978 1 85946 370 3 for all installations in the United Kingdom.

The Unit must be mounted plumb and level front to back and side to side. Mark a horizontal line on the wall using a spirit level. This line will be approximately 95mm below the location of the top face of the unit when fitted (excluding duct ports).

Fix the remaining Mounting Bracket to the unit using the M6 screws and washers provided, ensuring the interlock side is at the bottom. Do not overtighten. Mount the unit by locating the two Mounting Brackets together. Ensure a positive location is made between the two Mounting Bracket The Safety Bracket MUST be fitted.
Should be installed to have a minimum 5° fall from the unit. Titon recommend the use of diaphragm type waste valve in place of a conventional ‘wet’ trap which could dry out. Such as, BRE certificate no.
Ducting Connections Titon recommend the use of guidance given in the Domestic Ventilation Compliance Guide 2010 Edition ISBN-978 1 85946 378 9 and Approved Document Part F 2010 ISBN-978 1 85946 370 3 for all installations in the United Kingdom.
Ducting should be insulated where it passes through unheated areas and voids with the equivalent of at least 25 mm of a material having a thermal conductivity of ≤0.04 W/(m.K) to reduce the possibility of condensation forming. Where a duct extends externally above roof level the section above the roof should be insulated or a condensate trap should be fitted just below roof level.

Wiring Diagrams Volt-free setback switching of MVHR controller PCB using single-pole latching switch and / or volt-free normally open relay contacts. To avoid the unit being inadvertently left in Setback Mode, it is recom- mended that only one latching switch is tted.
Commissioning Controls The fan speeds of the Titon HRV Q Plus will require adjustment to ensure the flow rates achieved provide adequate ventilation. The Titon HRV Q Plus has 2 standard fan speed settings Continuous Speed and Boost Speed. The Continuous Speed and Boost Speed are programmed by placing the controller into Program Mode via the Program/Run Switch and changing the position of rotary potentiometers.
For the commissioning settings to be stored the unit needs to be powered up. Continuous Supply & Extract Speeds: Move Program/Run Switch to Continuous position. Rotate supply fan Continuous Speed adjustment potentiometer to achieve required supply continuous air flow. Rotate extract fan Continuous Speed adjustment potentiometer to achieve required extract continuous air flow.
Program / Run Header Link Boost Overrun Boost Overrun Timer is variable between 0 and 60 minutes. Rotate potentiometer to change overrun time. This can be done at any time. Humidity Sensor The Humidity Sensor’s trigger point is variable from 55%RH to 85%RH. Rotate potentiometer to change trigger point.
Following a controller reset the ventilation system will need to be fully commissioned. The procedure to reset the Titon HRV Q Plus controller is a simple three step operation. The unit will need to be powered up during the reset procedure.
The auralite® Indicator Panel will display a filter notification after 6 months of use. If filter maintenance is being done less frequently the notification can be reset. Replacement Filters are available from Titon. Titon HRV Q Plus Filters are available in two grades G3 and G4. Filter media should be replaced like for like.
How to Change Filters Remove Filter Covers by undoing the four screws. Slide out Filters. Filters can be cleaned by carefully using a vacuum cleaner, Filters should be replaced at least annually. MB models (excluding the HRV1.25 Q Plus) use unequal Filters. When replacing Filters ensure the filter with the open section is fitted into the right hand opening and in the...
Front Cover Removal ISOLATE the unit from mains power supply and allow sufficient time for all moving parts to stop. Loosen the two corner screws located on the bottom front of the unit. Completely remove the centre screw. Completely remove the Front Cover by pulling it away from the unit at the bottom and lifting.
