VENTILATION HOME SCREEN ICONS
The ventilation icon that appears along the left side of the
home screen will appear when a pre-defined system level
routine for ventilation is running. The system level routine
was defined by your installer using the thermostats’ avail -
able parameter settings.

VENTILATION SETTINGS
Menu Selection
From the thermostat’s home screen, go to menu > settings
> ventilation . The ventilation menu option will only appear
if a ERV or HRV is installed and configured by your installer.
Any Lennox ERV or HRV reference in this instruction can
be configured as either a single or two-speed unit.
When selecting this menu option, selections will be either:
• Timed or ASHRAE (either Timed or ASHRAE is set by
your installer during setup of your thermostat).
• On (always).
• Off (always).
Factory default is ASHRAE. Your installer will need to
change it to Timed if that mode is desired.
User Demand Ventilation
You can also select “ventilate now” to start a ventilation
function immediately. Those menu options are 10, 20, 30,
40 and 50 minutes, 1 hour, 1-1/2 hours, 2 hours, 2-1/2 hours,
3 hours, 3-1/2 hours and 4 hours and custom. Custom will
allow a specific time to be set.
NOTE:
Once ventilation is started, a notification appears
on the right-side of the home screen indicating a
time when that specific cycle will end and the option
to cancel the demand (see “Figure 11. Ventilation
Home Screen Notifications”).
NOTE: Fan is running icon may also appear on the left-side
of the home screen when ventilation is running and
there is no cooling or heating demand active.
REMINDERS
From the thermostat home page, go to menu > settings >
reminders .
This screen allows you to set reminders as either disabled
or 3, 6, 12 or 24 months and also custom by specific date.
The other options on this screen is to trigger the reminder
event either by calendar or actual system run-time.
Reminders may be set for ventilation maintenance and
ventilation filter. Once a reminder is set for a specific item,
touch done to return to the previous screen. An “expires on
date” will appear next to the item just set.
How the Dehumidistat Works
When using either an H/C ERV/HRV Ventilation Push But -
ton Control (Y8249) or H/C ERV/HRV Deluxe Ventilation
Control (Y8250) a built-in dehumidistat is present. The fol -
lowing information is provided on how it works.
High indoor humidity levels, during the heating season, have
become a problem in many well insulated, tight homes. Ex-
cessive condensation on the windows is a visual sign of
high indoor humidity levels. High indoor humidity levels can
result in mold, mildew and the eventual degradation of the
building structure itself. Your HRV reduces indoor humidity
levels when the outdoor air is drier than the indoor air.
These conditions usually occur during the heating season
when outdoor temperatures are less than 59°F (15°C) .
During the heating season, the operation of the HRV may
reduce indoor humidity levels sufficiently to eliminate the
need for further dehumidification. Use the adjustable dehu -
midistat feature located on the main control if your home re-
quires further dehumidification during the heating season.
This feature aggressively addresses high indoor humidity
levels by initiating high speed ventilation when the indoor
humidity levels rise above the set point on the control. Once
the humidity in the house is reduced, the HRV will revert
back to its previous setting.
We suggest operating the HRV for the first few days without
use of the Dehumidistat function to observe if a further de-
humidification effect will be required.
The dehumidistat operates in percentage of RH (relative
humidity) with 60 being high and 20 being low. If after a few
days, further dehumidification is required (the house is still
too humid), set the humidity level to a lower amount.
The average person is comfortable between 30% and 50%
RH. The Dehumidistat should be set to OFF for all seasons
except the heating season since a dehumidifying effect only
occurs when the outdoor air is dryer than the indoor air.
Dehumidistat Notes
Dehumidistat Disable
automatically disables the dehu-
midistat function on the main control when outdoor tem-
peratures exceed 59°F (15°C) for a full 24 hour period. All
other HRV features and functions operate normally while
the Dehumidistat Function is disabled.
Dehumidistat Re-Enable
automatically re-enables the de-
humidistat function when the outdoor temperature drops
below 59°F (15°C) for a full 24 hour period or if the HRV is
reset (unplugged for 30 seconds).
