Night Mode
Night Mode sets the HRV to 18 degrees for 4 hours, after which it will return to its
previous setting automatically. Night Mode is best used in summer before going to
bed in the evening. Once set, your HRV System will use the cool air in the roof space to
bring the room temperature down, and create air flow in the house to help with a
more comfortable night sleep.
To activate press and hold the 'Down' arrow button until you see the set temperature as
a flashing '18'. This will occur 3 seconds after the flashing '--' is displayed, so don't release
the button until the flashing '18' is seen. To de-activate, press the 'Up' or 'Down' arrow
button once.
Filter Gauge
The Filter Gauge is an indicator of how much percentage of use the filter has remaining.
To display the filter gauge press the 'FUNC' button twice within a second and then after
another second, press it again. 'Fil' will be displayed with a number under it. This number
is a percentage of filter use remaining. Over time the number moves towards zero percent
and the filter needs to be replaced when it gets close to zero. This will also be indicated
by the Replace Filter Light (see below).
Note: For systems with an ATU, you will need to turn the system off first, by pressing the
'Power' button.
Replace Filter Light
If the Replace Filter Light is flashing, then it's time to replace your filter. Doing this
without delay will ensure your HRV System continues to work at its best performance.
Power Failure
During a power failure the unit will retain all settings, including the Set Temperature and
the key pads locked state.
Ventilation Mode – Adjusting the Ventilation Level
This setting determines how much air your HRV will deliver when the temperature inside
your roof cavity is undesirable – for example, on a cold winter night or hot summer day.
For bad condensation problems a higher setting can be selected. A higher setting will
reduce condensation but may also reduce the temperature during cooler times of the year.
To change this setting, first turn the system off by pressing the power button. Next, press
and hold the 'Down' arrow button until the display is lit (3 sec) – the display will now show
'01' beside the 'Roof Temp' and another number beside the 'House Temp'. Press the 'Power'
button to change the setting. The setting can be a number from '1' through to '6'.
To exit settings mode press the 'FUNC' button when the setting has been made. Settings
mode will exit in 2 minutes, if no key is pressed.
ATU control (ATU system) – Optional
The Air Tempering Unit can run in two modes (Air tempering mode or thermostat mode).
Air Temper mode uses a lot less power and only turns on the heater to help reduce
condensation. Thermostat mode turns on the heater whenever the HRV system needs
to heat.
To enable air tempering mode, briefly press the 'FUNC' button once. The ATU symbol will be
displayed. To disable the air tempering mode briefly press the 'FUNC' button again.
The ATU symbol will go off.
To enable thermostat mode, press and hold the 'FUNC' button for 3 seconds, until the ATU
symbol flashes. To disable the thermostat mode, briefly press the 'FUNC' button.
The ATU symbol will go off.
