DIFFERENTIAL SETTINGS
The temperature differential is your comfort level. A lower differential means your system may
cycle with greater frequency but will control closer to desired setpoint temperature.The second
stage delay is a timed delay to indicate how much time should pass before the second stage is
turned on. This is an energy saving feature. To use less energy, set this higher. For greater
comfort, set it lower.
HEATING and COOLING LIMITS
To prevent individuals (probably your kids) from adjusting the
thermostat too hot or too cold, you can limit the maximum setting
for the heating and cooling modes. This will help you save on
energy costs.

SENSOR SETTINGS
This screen will appear when a remote indoor sensor (9020i) is connected to the thermostat.
USE LOCAL SENSOR will disable the remote sensor and only sense from the thermostat.
AVG. LOCAL/REMOTE will take a temperature reading from both the thermostat and the remote
sensor and average the two for even temperature control. USE REMOTE SENSOR will disable
the sensor in the thermostat and only control from the remote location.
SECURITY SETTINGS
In order to prevent tampering with the program and your desired settings, two levels of security
are available.The first will allow only temporary changes to the temperature. It protects all other
programmed setpoints. The second will restrict changes to EVERYTHING, including temporary
changes to the temperature.
SECURITY CODE
In this screen you enter a four-digit code. Use the UP or DOWN button to change the first value,
press SELECT. The second digit will be highlighted. Repeat for all four values. And don’t forget your
code. If you do, you will have to reset the entire thermostat and that will erase all the schedules
you’ve programmed into the unit.
When would I need to change the USER settings?
About the only features you may need to change are the FILTER INTERVAL (in case you get a new type of high efficiency filter), the
temperature differentials (if you desire additional comfort), and the security settings. All the other settings probably will not need to be
changed.

AUXILIARY HEAT
The 9720i can be set to use your 2H/2C heat pump internal auxiliary heating or to use an
external add-on source. The add-on feature will be used most often when a single stage heat
pump uses a gas or electric furnace as its second stage of heating.
RESIDUAL COOL
In order to get greater efficiency from the cooling system, the fan can be programmed to run for
0 (OFF), 30, 60, 90, or 120 seconds after the air conditioner has shut off.
BALANCE POINTS
This screen will appear only when the optional outdoor sensor (9025i) is connected to the
thermostat. When this sensor is used with the 9720i, you can set the lower and upper
temperatures to disable or enable 2nd stage heat.
AUTO CHANGEOVER
When turned on, the thermostat will switch automatically between heating and cooling to maintain
the optimal temperature in your home.

CONTACT INFORMATION
This allows the servicing HVAC contractor to put their name and phone number into the thermostat to
remind you when service may be required.
SERVICE MONITOR MENU
Two menus are available, the Service Monitor and the Filter Monitor. Both can be set based on the HVAC
system run time or calendar based. See Reminder Interval.
The Service Monitor can be set from OFF to 360 Days in 30 day increments or OFF to 980 in 20 hour
increments.
The Filter Monitor can be set from OFF to 360 Days in 30 day increments or OFF to 980 in 20 hour
increments.
REMINDER INTERVAL
The Reminder Interval can be set for either HVAC System run time or based on the calendar.
If Run Time is chosen, the service reminder will be set in hours. After the HVAC System has been
operating for the selected number of hours, a Service Reminder will be displayed informing you that
service is suggested for your system.
If Calendar Time is chosen, the service reminders will be set in days. After the selected number of
days has passed, a Service Reminder will be displayed informing you that service is suggested for
your system.
When would I need to change the INSTALLER settings?
NEVER! The INSTALLER SETTINGS are selected based on the type of equipment you have in your home. This feature should be
set only by a certified HVAC technician. Changing these settings could result in higher energy costs and may even damage your
equipment. There is a security lock on this feature to prevent tampering. USE IT!

When should I change the batteries?
Only the model 9700i operates with batteries. The 9701i, 9715i and 9720i operate from power provided by your
heating/cooling system.
Generally the batteries will last 18-24 months. The thermostat will tell you when to change the batteries. A
battery symbol will appear just below the temperature display. The thermostat will continue to operate for a
short period of time with this notification on the display. The low battery warning supercedes all other notifications including outdoor temperature and the filter monitor.
If the WARNING screen is displayed, the thermostat will shut down all
operations, including heating and cooling. It’s important to change the
batteries promptly if this screen appears.
How do I change the batteries?
Simply slide the battery door to the right. Remove
the two right most batteries first. Then remove the
two left batteries. The screen to the left will
appear. This screen will help you orient the new
batteries. Replace with four fresh AA alkaline batteries. REPLACEMENT TIP: It’s easier to replace
the two left most batteries first, then the right ones.
