If no updates are received from the master controller for any value for the time defined in
'Display Values Receive Timeout', that value is considered stale and dropped from the list
to be displayed, until a fresh value is received again. This function can be disabled by set-
ting the parameter to 0.
‘Home Display Parameter’ is the display value that the screen returns to when no buttons
