6.1 General Description
• The text display is used to display information about
the appliance and the system and to alter the set-
tings 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.
