6.1 General Description
• The text display is used to display information about 
the appliance and the system and to alter the settings 
displayed.
• Once the appliance has been in operation for one 
day, the text display module has a power buffer 
period of about 10 hours during which it will run with-
out the mains power supply. After that period has 
elapsed, the clock function shuts down but all other 
settings are retained.
