NOTE: Copy command will appear only if programming an individual day.
Use the UP or DOWN button to highlight the day to copy to. Press YES / NO. A YES will appear next to the day. Do this for each day to which that program is to be copied. Press FINISHED when complete.
After pressing FINISHED, you can choose to program other days or exit. YES will take you back to the Select Program Days screen. NO will exit you to the main screen.
Events
An event is a programming period. This could be the period in the morning when the facility is occupied. It could be the period when no one is at work. It could be the evening. The time for an event is selected based on when you want the event to occur. For example, if people start to arrive at the facility at 6:30 AM, set the first event for 6:30 AM. The thermostat will automatically make sure the environment is at the desired temperature selected for that event by the time you desired. This thermostat can be selected for 2, 4, or 6 events.
Energy Saving Programs
The thermostat is set with the US EPAENERGYSTAR® recommended times and temperatures for optimal energy savings. You can change these to suit your lifestyle. The best rule is to examine your schedule and set the times and temperatures that best fit. This thermostat is so versatile, you can easily temporarily change temperatures or programs at a whim.

More Detailed Information on the USER SETTINGS
DIFFERENTIAL SETTINGS
The temperature differential is your comfort level. The differential is the difference from the setpoint before your heating or cooling system will turn on. The 9915i and 9920i models also have 2nd stage differential. If the temperature falls below (or above for cooling) the setpoint by the 1st stage differential plus the 2nd stage, the auxiliary heating (or cooling) system will turn on.
The 2nd stage delay is a timed delay before the second stage will turn on if the setpoint has not been achieved within that time frame.
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.
COOLING and HEATING LIMITS
To prevent individuals 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.
Changing USER Settings
About the only features you may need to change are the temperature differentials (if you desire additional comfort), and the security settings. All the other settings probably will not need to be changed.
INSTALLER SETTINGS
The INSTALLER SETTINGS are set during the initial installation. They tell the thermostat how to function with your heating or cooling equipment. The following is a brief overview and discussion of these settings.
INSTALLER SETTINGS
The INSTALLER SETTINGS are set during the initial installation. They tell the thermostat how to function with your heating or cooling equipment. The following is a brief overview and discussion of these settings.
AUXILIARY HEAT
The 9920i 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 9920i, you can set the lower temperature (below which the heat pump will not run) and upper temperature (above which the 2nd stage heat will not run). This promotes efficient operation of the heating system.
AUTO CHANGEOVER
When turned on, the thermostat will switch automatically between heating and cooling to maintain the optimal temperature in your home.
ENERGY-EFFICIENT RECOVERY
When turned on, the thermostat will look up to two hours before the next event and anticipate when to turn on to reach the desired temperature.
DEADBAND SETPOINT
Deadband is used with the AUTO CHANGEOVER feature. The dead band is the temperature difference from the setpoint temperature during which the heating or cooling will not be turned on. This is adjustable from 2-8°F (1.0-4°C).
SECURITY CODE
Enter a code to prevent changes to the INSTALLER settings.
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 for the 9920i, the System Monitor and the Filter Monitor. Three menus are available for the 9901i and the 9915i, the Cool Monitor, the Heat Monitor, and the Filter Monitor. All can be set based on the HVAC system run time or the calendar. See Reminder Interval.
All selections 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 the 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.
TEMPERATURE OFFSET
The OFFSET or calibration feature allows the installer to recalibrate the thermostat if the displayed room temperature is not the actual room temperature. The OFFSET feature also allows you to display a temperature that is different from the actual room temperature.
SHORT CYCLE PROTECTION
You can change or remove the timed delay that protects the compressor in an air conditioner or heat pump system. Short Cycle Protection should be turned off ONLY if the HVAC system has other protective circuits that guarantee a compressor off time. This feature is adjustable from OFF to 5 minutes in 1-minute increments.
The INSTALLER SETTINGS are selected based on the type of equipment you have in your facility. This feature should be set only by a certified HVAC technician. Changing these settings could result in higher energy costs and may even damage the equipment. You should only change the FILTER MONITOR length should you get a new type of filter.
Energy Efficient Recovery™ (EER™)
Energy Efficient Recovery™ is an energy-saving feature. During a setback period (or set up in cooling), it allows the thermostat to look up to two hours ahead to determine when to turn on the heating (cooling) system. During this time period, the second stage is locked out to allow the first (and most efficient stage) to bring your facility to the desired temperature.
Indoor Sensor
The remote indoor sensor (part #9020i) can be used to improve the comfort of your home. When used in conjunction with the local sensor on the thermostat, the two sensors average the sensed temperature and control to that average temperature.
You also can use the remote sensor in a stand-alone situation when you want to control the temperature in a remote area but have the thermostat in a secure location.
Outdoor Sensor
The remote outdoor sensor (part #9025i) can be used to aid in the comfort of your facility or simply as a sensing device to inquire about outdoor conditions. In most applications, the thermostat will have a display of the temperature sensed by the remote outdoor sensor. With a heat pump system, the remote outdoor sensor can help determine when to turn on the second stage of heating for optimal comfort. The remote outdoor sensor should be installed on the northern wall of the facility, away from direct sunlight or other heat sources that may affect its sensitivity.

Power Outage Protection
The thermostat automatically retains the time of day for approximately two hours in the event of a power outage. All other programmed parameters are stored permanently in memory. So, if the power is out for more than two hours, simply reset the clock. See page 4.
Resetting to Factory Conditions
To reset the thermostat to factory conditions, press the UP button and the LEFT button at the same time. Hold for 8 seconds. The time of day will display 12:00 indicating a reset has occurred.
NOTE: This will erase all programming and return the thermostat to the factory conditions including the installer settings. Use this only as a last resort.
