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 screen for humidification in automatic mode
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.

Dehumidifier control
If dehumidification is installed the thermostat can be configured, 
through the installer set-up, to control dehumidification with 
either a whole home dehumidifier or with the air conditioner 
(cooling unit). 
Press   button to select Dehumidify and enter the 
Dehumidifier Control screen.
Manual mode: 
screen cycles 
recommended 
humidification 
setpoints for 
various outdoor 
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.

Outdoor temperature sensor (included)
Outdoor temperature can be measured by attaching the included sensor to the 
S1 and S2 terminals. The outdoor sensor must be enabled in the thermostat’s 
Installer Setup menu. 
Heat pump models can use the outdoor temperature to eectively utilize the 
heat pump:
• When the outdoor temperature is less than the Low Balance Point, the heat 
pump is locked out and only auxiliary heating is used. 
• When the outdoor temperature is higher than the High Balance Point, the 
auxiliary heating is locked out and only the heat pump is used to provide 
heating.
Indoor Air Quality functions can use the outdoor temperature sensor to:
• Control humidification setpoint based on outdoor temperature to prevent 
condensation.
• Lock out humidification for temperatures over 60°F (15.6°C) or below -30°F 
(-34.4°C).

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.
