Section TPxxxHMB/HMBE Product Overview

Controls & Features

The auralite HRV Q Plus units are controllable by various volt free switches and sensors. The following describes the controls and features of the auralite HRV Q Plus units and how they are controlled. Ensure all controls are adequately labelled, indicating their function clearly.

Filter Covers

The units are tted with removable lter covers on the front panel.

auralite®

auralite® is available separately as an optional add-on. auralite® is a low voltage hard wired remote LED ventilation system

status indicator, designed to t a standard UK patress or recessed backbox. The indicator has six LEDs which display:-

 Normal Solid light - Unit is running at Continuous Speed.

Flashing light - Unit is running at Setback Speed.

 Frost Unit is in Automatic Frost Protection mode.  Filter Filters require change.

 Boost Solid light - Unit is running at Boost Speed.

Flashing light Boost Alert is active.

 Summer Unit is in Summer bypass.  Fault Unit has a fault - Contact the installer.

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. The Setback Speed can be enabled by connection of a volt free one-way switch, or combined with the Boost Speed with the 3 position switch TP 508.

Continuous Speed

Continuous Speed is the normal continuous extract and supply air ow running speed of the units.

Boost Speed with Overrun Timer

Boost Speed increases the extract and supply air ow. Boost Speed is congured with Step-less independent fan controls and includes an Overrun Timer variable between 0 and 60 minutes. The Boost Speed can be triggered by any device which provides a volt free one-way switch, such as a PIR, thermostat, humidistat or a standard one-way switch. If the unit is left Boost (latching switch) for longer than 2 hours the Overrun Timer is disabled meaning the HRV will return to Continuous Speed as soon as the switch holding the unit in Boost is released.

Ventilation

System

auralite® Indicator Panel

auralite® Boost Alert

Boost Alert is a timer designed to prevent the HRV being inadvertently left in Boost for long periods of time. Once the HRV is placed in Boost the timer is started and after 2 hours Boost Alert will be activated. This is indicated by the Boost LED on the auralite® Indicator Panel ashing. Once Boost Alert has been activated the Overrun Timer is disabled meaning the HRV will return to Continuous Speed as soon as the switch holding the unit in Boost is released.

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.

SUMMERboost®

An optional SUMMERboost® facility is available that allows both the supply and extract fans to run at full speed whenever the Summer Bypass is activated. By default SUMMERboost® is disabled by a Link Wire, see Wiring Diagrams. Removal of the link wire will enable SUMMERboost®. When SUMMERboost® is trigged by Summer Bypass the increased fan speed can be prevented either Manually or Automatically. Manual - This is by means of a volt-free switch wired directly into the controller PCB. Automatic - This is by means of a dedicated wall mounted room thermostat. SUMMERboost® will only operate when the temperature has exceeded the thermostat setting. Should the room temperature fall below the thermostat setting, then SUMMERboost® will not operate.

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 ow 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. As internal temperatures rise Automatic Frost Protection will increase the supply ventilation ow rate back to the commissioned settings.

Integrated Humidity Sensor

Units are tted with an Integrated Humidity Sensor. This continuously monitors the relative humidity (RH) of the extracted air and triggers Boost Speed when the relative humidity rises over the set threshold. The Humidity Sensor’s trigger point is variable from 55%RH to 85%RH and is congured using step-less independent potentiometer.

Enthalpy humidity-recovery

Units with the E sux use an enthalpy heat recovery core that recovers some of the humidity as well as heat.

Controls

The fan speeds of the Titon HRV Q Plus will require adjustment to ensure the ow 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. When applying power for the rst time, the unit can take up to four minutes to start operating. Prior to the rst commission set Continuous Speed potentiometers to minimum and Boost Speed potentiometers to maximum or reset the controller.

Control Parameters

 The Boost Speed cannot be set lower than the Continuous Speed.  The Continuous Speed cannot be set higher than the Boost Speed.  All switching inputs are disabled when the Program/Run Switch is in Continuous or Boost positions.  Speed control potentiometers are disabled when the Program/Run switch is in centre Run position.

For the commissioning settings to be stored the unit needs to be powered up.

Continuous Supply & Extract Speeds:

1. Move Program/Run Switch to Continuous position.

2. Rotate supply fan Continuous Speed adjustment potentiometer to achieve required supply continuous air ow.

3. Rotate extract fan Continuous Speed adjustment potentiometer to achieve required extract continuous air ow.

4. Return Program/Run Switch to centre position to exit commissioning.

Boost Supply & Extract Speeds:

1. Move Program/ Run Switch to Boost position.

2. Rotate supply fan Boost Speed adjustment potentiometer to achieve

required supply boost air ow.

3. Rotate extract fan Boost Speed adjustment potentiometer to achieve

required extract boost air ow.

4. Return Program/Run Switch to centre position to exit commissioning.

Controller Reset

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.

1. Rotate the Supply and Extract Continuous Speed potentiometers fully anti-clockwise.

2. Rotate Supply and Extract Boost Speed potentiometers fully clockwise move the Run/Program Switch from the Run

position to the Continuous position, from the Continuous position to the Boost position and back to the Run position. To ensure that the reset switch movements are registered by the controller wait two seconds between each switch movement. Controller reset is now complete.

Hardware Reset

Certain conditions (repeated supply interruptions etc.) can activate the automatic motor protection mode. Whereby the fan motors are prevented from operating. This requires a hardware reset to return the unit to normal operating mode, to achieve this power to the unit should be switched o for 5 minutes, restoring the power after this time will reset the hardware of both the motor and PCB. Commissioning settings are not aected during a hardware reset.

Section TPxxxB/BC/BE Product Overview

Control & Features

The TPxxx B, BC & BE units are programmable with Titon controllers.

Enthalpy humidity-recovery

Units with the E sux use an enthalpy heat recovery core that recovers some of the humidity as well as heat.

Boost Overrun Timer

A programmable timer that controls the time the HRV remains at Boost Speed after all boost switches have been released.

Boost Delay Timer

A programmable timer which can be used to delay the HRV running at Boost Speed after a boost switch has been activated.

Boost Inhibit

A programmed time period that prevents the HRV switching into Boost Speed or SUMMERboost®.

Internal Humidity Sensor

The HRV has a relative humidity (RH) sensor. The RH sensor can be programmed to switch the HRV into Boost Speed.

Filter Change Alert

The unit can display a lter warning via a connected controller

4 x Fan Speeds

The units have 4 programmable speed settings. All speeds allow independent speed setting of both supply and extract ventilation rates

Summer Mode

Summer Mode operates by slowing or stopping the supply fan. This reduces the supply of From Atmosphere air to the dwelling. Summer Mode is triggered automatically or via a Volt

Free input. Summer Mode must not be enabled or installed in dwellings where open ue combustion appliances are used.

SUMMERboost®

SUMMERboost® allows both the supply and extract fans to run at full speed whenever the Summer Bypass is activated. By default SUMMERboost® is enabled.

Summer By Pass

Duct Heater Control

To maintain ventilation ow rates where prolonged periods of very low temperatures occur, the facility for the control of an electrically powered Duct Heater is provided, MAX 1500W. The Duct Heater is placed in-line between the outside supply vent and the From Atmosphere terminal on the HRV. In these applications, the heater is used to pre-warm the outside fresh air supply before it enters the HRV.

2 x Proportional Sensor Inputs

Enables connection of environmental sensors to the HRV which can be used to proportionally control HRV fan speeds.

3 x Volt Free Inputs

Enables the connection of single pole momentary switches, latching switches or normally open relay contacts to the HRV. These can be used to switch between fan speeds or control SUMMERboost® and Summer Mode.

2 x Live Switch Inputs

These inputs are used to switch the HRV to Boost Speed via a switched live input.

Frost Protection Program

During very cold weather, the Frost Protection Program will detect temperatures that could cause ice to form inside the unit. It will reduce or stop the supply ventilation rate, thus allowing the warmer stale air to raise the temperature within the unit cell to such a level that prevents the formation of ice. As temperatures rise the Frost Protection Program will increase the supply ventilation ow rate back to the commissioned settings.

Multiple Internal Temperature Sensors

The unit measures From Atmosphere and To Atmosphere air temperatures in real-time. Additionally the temperature of the heat cell is monitored.
