TEMPERATURE: Fahrenheit or Celsius Temperature will be displayed in F or C.

CLOCK SETTINGS Displays time in standard 12-hour format or military format.

SETPOINT TEMPERATURE Each event has a setpoint temperature. Choose whether to display this value or not.

NUMBER OF EVENTS PER DAY Select events per day. Choose from 2, 4, or 6 events per day.

Page 19

DIFFERENTIAL SETTINGS The temperature differential is your comfort level. The differential is the difference from setpoint before your heating or cooling system will turn on. The 9915i and 9920i models also have 2

stage differential. If the temperature falls below (or above for cooling) the setpoint by the 1ststage differential plus the 2ndstage, the auxiliary heating (or cooling) system will turn on.

The 2ndstage 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.

SECURITY SETTINGS In order to prevent tampering with the program and 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.

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 2ndstage 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.

Page 23

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 deadband 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.

Page 24

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 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.
