Filter Covers
The units are tted with removable lter 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. 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 congured
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.
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.
9
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 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.
Summer Mode
In properties where it is desirable to reduce the supply of warm fresh air during hot
weather, but where full Summer Bypass may be inappropriate or not available, the
optional Summer Mode operation is available. Summer Mode operates by stopping
the supply fan. Summer Mode can be triggered 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. In
this conguration Summer Mode will only operate when the temperature within
the room has exceeded the dedicated thermostat setting. When Summer Mode is
selected the supply fan will remain o even if the HRV is placed into Boost.
Summer Mode must not be installed in dwellings where open ue combustion
appliances are used. Summer Mode must not be installed on HRV Q Plus MB units.
