Lock Operation Explained
Set Temperature Lock
When the topside is set to lock the set temperature, pressing either ‘Temp
Up’ or ‘Temp Down’ during normal operation will display the currently set
temperature as usual. Pressing either ‘Temp Up’ or ‘Temp Down’ button
again, will display ‘LOCK’ on the screen brie
fl
y, instead of allowing the set
temperature to be changed.
Settings Menu Lock
When the topside is set to lock the user settings menu, pressing the
‘Menu’ button will display ‘LOCK’ instead of ‘MENU’. This prevents
accessing the user settings menu, changing the heat mode (standard or
economy, explained later in this section), and accessing the initial system
con
fi
guration menu.
Both Temp & Settings Menu Lock
When the lock is set to ‘BOTH’, both the above described locks are put into
place; locking the set temperature, heat mode, and the user and system
con
fi
guration menus.
Unlocking the Topside
Unlocking the topside, regardless of which lock is implemented, is done
as follows:
Press (which will display ‘MENU’, or ‘LOCK’
depending on which lock is in effect)
Then press within 3 seconds.
