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 desired settings, two levels of security are avail-
able.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.
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.
