HOME SCREEN
OVERVIEW:
The Home screen displays the current temperature, relative humidity, VOC, CO2, and status of the CERV. It
additionally provides quick access to other screens, such as heating and cooling setpoints, status and alerts, and the
top menu. The color of the screen, along with some of the icons, will change depending on the current mode that the
CERV is operating in. The possible modes are:
Assess –The CERV is recirculating air throughout the house in order to obtain accurate readings of the home’s
overall health and comfort. When the CERV does not need to ventilate or heat or cool, it may simply sit in its
off mode, where approximately every 10 minutes it will do an assessment for 2 minutes.
Vent (Heat/Cool/Setpt) –The CERV may decide to ventilate the home for various reasons. The CO2/VOC
levels may have gone above the setpoint, a wireless ventilation switch was triggered, a timed ventilation event
may have been started, or the CERV may have simply decided that it is more efficient to heat or cool the home
with outside air. If the home is within the heating and cooling setpoints, but the CERV is ventilating, the
screen will be green and the current Mode will show Vent Setpt
Recirc (Heat/Cool/Setpt) –When the inside temperature is outside the bounds of your heating or cooling
setpoint, the CERV will go into a recirculation heating or cooling mode as long as it has detected that you do
not need any ventilation.
Off –The CERV has determined that your air quality is acceptable and your inside temperature is satisfactory.
It will conserve energy by turning itself off. After every 10 minutes of sitting off, the CERV will do an
assessment.
Other Notes:
The colored bars below the CO2/VOC readings indicate how the air quality levels are compared to your
setpoint. Green indicates that your air quality is acceptable, yellow indicates that the pollutant level is nearing the
ventilation setpoint, and orange indicates that the pollutant level is above the setpoint (where it should start
ventilating).
