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.
Visio-4 Alarm Configuration
(Engineering Level)
The configuration of the alarm thresholds can only be accessed with the engineering password. Once the engineering menu screen has become visible the user can select which channel to be configured. The channels that are not in use will not be visible on the menu (Select dip switches at the back of the screen to enable additional channels.)
Below is an extract from the setup manual which explains how the user can setup the alarm thresholds for both the warning screen and alarm screen.
