Indoor Air Quality functions
Power and battery replacement
This thermostat can be AC powered, battery powered, or both
(to provide backup power for communication with the Control4
system). The thermostat uses four alkaline AA batteries.
The thermostat has a memory backup that saves the thermostat
settings in case of a power interruption. The system settings will
be retained, but the clock resets after both battery and AC power
are removed. Clock synchronization comes from the connection
to the Control4 system. To access the batteries for replacement,
remove the bezel as shown.
Automatic or manual mode is configured by the installer. To
determine which mode the thermostat is set to, see the diagrams
on pages 3 and 4.
In automatic mode you will receive the optimum amount of
humidity so that your home and its furnishings are protected
from the damaging eects of excess condensation or low
humidity during heating season. The thermostat automatically
adjusts your home’s relative humidity based on the outdoor
temperature.
The humidity setting needs to be set initially to meet your
home’s conditions. Follow these steps when adjusting your
thermostat.
1 Adjust the humidity setting to “3” which is within normal
range. During the next 24-48 hours it may be necessary to
adjust the setting for more or less humidity, depending on
your personal comfort and home’s requirements.
2 During the coldest portion of the first heating season, minor
adjustments may be necessary. This is dependent upon your
home’s construction.
The relative humidity in your home will now be accurately
controlled to meet your needs and should not need further
adjustment during future heating seasons.

Humidifier control
If humidification is installed it can be controlled in two modes,
automatic or manual.
Press button to select Humidify and enter the Humidifier
Control screen.
Indoor Air Quality functions
Event-Based™ air cleaning
If installed, air cleaning can be controlled through the Control4
system. Air cleaning will activate the fan for the purpose of air
cleaning and can operate in five dierent modes as defined on
this page.
O: The air cleaner will not call the fan for the purpose of air
cleaning.
Note: If air cleaning is installed, air cleaning will still
occur during normal fan operation during heating,
cooling or other indoor air quality events.
Constant Clean: This option will provide the maximum amount of
air cleaning available. The air cleaner will be active for 24 hours a
day, seven days a week.
Automatic: The air cleaner will run a minimum of 30 minutes
every hour. The air cleaner will monitor the amount of time your
heating and cooling system runs; if 30 minutes is not reached
the air cleaner will automatically turn on. This will maximize the
amount of air cleaning while minimizing energy consumption.
Event Clean (3 hour cycle): When selected, the air cleaner
will run for 3 hours continuously and then return to the most
recent mode of O, Automatic, or Constant Clean. This option
only cleans the air when needed; an example would be after
vacuuming.
Allergies (24 hour cycle): When seasonal allergies spike and
outside air quality is at its worst, choose this option. Your air
cleaner will run continuously for 24 hours, then return to the most
recent mode of O, Automatic, or Constant Clean.
Note: The thermostat will manage fan and air cleaning
selections when the selections overlap.

(cooling unit).
Press button to select Dehumidify and enter the
Dehumidifier Control screen.
Manual mode:
screen cycles
recommended
humidification
setpoints for

temperatures
The thermostat will allow you to set the desired humidity (%
relative humidity) level in your home and can be used to turn the
dehumidification On or O.
Use the dehumidification adjustment to set the dehumidification
setpoint to 60% when first installed. Allow dehumidification to
run until the initial setpoint is reached, before deciding if you
want to change the humidity setting.
Raise the setting if you prefer the air to be less dry; this will
reduce the amount of time that dehumidification runs.
Lower the setting if you prefer the air to be more dry; this will
increase the amount of time that dehumidification runs.
Your comfort is the best measure of how to adjust your setting.
When first installed, your dehumidifier has to remove all the
moisture that is initially in your home. The home acts like a
sponge so the moisture in the materials of your home is at the
same level as the air. After drying the air, the materials of the
home will release the moisture back into the air until they are
again at the same level. As a result, it is not uncommon for
dehumidification to operate for an extended period of time when
it is first installed.
Energy Saving Tip #1:
Adjust the setting to be as high as is comfortable to reduce
dehumidification run time – if it feels clammy or smells damp or
moldy lower the setting. To save energy, turn the dehumidifier
control OFF when you open your windows just as you would with
air conditioning.
Energy Saving Tip #2:
If vacating your home for an extended period in the summer, set
the relative humidity at 60% and set the cooling setpoint as high
as you are comfortable setting it to in cooling mode. Consult with
appropriate professionals regarding the highest temperature that
is safe for your pets or possessions. This will keep the humidity
at a controlled level to help prevent mold while minimizing the
amount of the cooling energy used.
Dehumidifier Control screen with only dehumidification installed
If dehumidification is done with the air conditioner, the
thermostat will cool up to 3°F beyond the cooling setpoint for
dehumidification. Note overcooling may not be sucient to meet
the dehumidification setpoint.

Program schedule and holds
Program schedule and holds
Understanding program schedules
Setting the schedule for the thermostat is done at the Control4
system.
Progressive recovery
The Progressive Recovery feature allows the thermostat to
activate the heating and cooling equipment prior to a scheduled
event in order to reach the desired temperature at the start of
that scheduled event.
Example: If the Next Event time is 6 a.m., and the temperature is
70°, the heat will come on before 6 a.m., so the temperature is
70° by 6 a.m.
Program schedule holds
Press button to initiate a Next Event, 2 Hour or Permanent
hold. All options will be displayed and the current hold selection
will flash.
After 7 seconds without any button presses the selected hold
will be accepted by the thermostat. After the option of 2 Hour
if button is pressed again, no hold options will be displayed.
This indicates no hold option is to be selected and can be used to
cancel any active holds. Pressing button again will display all
hold options with Next Event selected.
While in Next Event, 2 Hour, or Permanent hold, the temperature
setting and fan mode can be adjusted and will stay at that setting
until the hold ends or is cancelled.
Next Event hold will override the temperature setting and fan
mode for the current schedule event and will remain active until
the next schedule event occurs.
2 Hour hold will override the temperature setting and fan mode
for the schedule events and will remain active for two hours from
the time the hold is initiated.
Permanent hold will override the temperature settings for all
events.
O: Ventilation will not run.
Automatic: Ventilation will cycle based on the parameters set by
the installer to meet your home’s ventilation requirements.
3 Hour Event: Ventilation will be constantly energized for 3
hours and then the fresh air mode will return to O or Automatic
depending on which was mode was most recently active. This
option is used when fresh air is needed. An example would be
after cooking.
24 Hour Event: Ventilation will be constantly energized for 24
hours and then the fresh air mode will return to O or Automatic
depending on which was mode was most recently active. This
option is used when a large amount of fresh air is desired. An
example would be a day with desirable outdoor conditions.

Power and battery replacement
This thermostat can be AC powered,
battery powered, or both (to provide
backup power for communication with
the Control4 system). The thermostat
uses four alkaline AA batteries. Batteries
are optional but recommended if your
thermostat was wired to run on AC power
when installed. If the thermostat will be
AC powered, the thermostat should be
powered from 24VAC before installing
batteries to confirm AC power is present.
For heat pump systems, the C terminal
must be connected to the common of the
24VAC transformer for the system fault
indicator to operate.
The thermostat has a memory backup that
saves the thermostat settings in case of
a power interruption. The system settings
will be retained, but the clock resets after
both battery and AC power are removed.
Clock synchronization comes from the
connection to the Control4 system. To
access the batteries for replacement,
remove the bezel as shown.
