Visio-4 User Options
(Operator Level)

The intuitive menus in the Visio-4 allows the end-user to easily change the operation to a sleep/setback mode whereby the monitoring of sensors is suspended until such time that the room is back in use or the process in the room is back in option. When the room status is selected as non-occupied the home screen will not display any values only a message showing that the room monitoring is in setback mode (See image below)

Below-left is an extract from the setup manual which explains how the user can disable/enable the audible buzzer and adjust the mute time.
