For automatic units, there is Feature 6DL that can be activated in the Group G controller to require manual retransfer to the Normal source. When activated, the controller will wait for the end-user to press the Transfer button to complete the retransfer action after the retransfer to Normal time delay has expired. The manual retransfer will be overridden in the event of loss or unacceptability of the Emergency source.
To activate, go to Main Menu --> Settings --> Features --> Feature 6DL and place a check on the tickbox. The default password is 1111.
