Unit Configuration
Room Controller Configuration Setup
To enter installer setup, hold the “MODE“ button down for 5
seconds. After 5 seconds, a “10“ will appear. This indicates that the
user is setting the first software configuration item. To check the
value of configuration item 10, press the “MODE” button. The
value of the Heat/Cool vs Cooling only remote configuration will
be displayed along with the “SET TEMP” icon to indicate that the
number displayed is the configuration data. To change the
Heat/Cool vs Cooling only remote Configuration, use the
“UP“/”DOWN“ buttons. To move to the next setting, press the
“MODE“ button again and the “10“ will be
displayed. Press the up button and the display will change to “11”.
The mode button will toggle the display between the software
configuration index (i.e. “10“, “11“, etc.) and the configuration
value. The “UP”/”DOWN“ buttons will change either the index or
the value, which ever is displayed at the time. Press the ”FAN”
SPEED button to exit Configuration Setup Mode. This mode will
exit automatically after 10 seconds of no buttons being depressed.
Once a configuration value is changed, the last value displayed will
be the new configuration value for the Room Controller.
The only way to abort a configuration change is to change the
value back to its original value.
The
BOLD
values are the default values from the factory.
