Advance Building Control

The General Purpose Override (GPO) unit has been specifically designed to be an easy to use, auxiliary interface to the Ambiflex ‘Advance’ range of controllers. The GPO can also be integrated with any Building Management System that can take a volt-free Digital Input together with a 0-10 Volt DC Analog Input and provide volt free Digital Outputs.

The override unit was designed to be simple for the user, and to retain the inherent flexibility to allow the specifier more choice in parameters. For example, a reset is available both for the timer and the analog adjust; the timer can be set to 3 hours or 6 hours with 15 minute or 30 minute options and the analog adjustment may be scaled over the desired temperature range.

Features

• Analog adjust (typically temperature) - the unit provides a 0-10V signal biased at 5V which can be adjusted up or down
• Analog adjust can be reset remotely to its mid value
• Extension timer - the unit provides a volt free contact for a digital input for any BMS system
• Extension timer can be remotely cancelled or frozen
