4 Remote User Interface
In addition to the unit-mounted user interface provided with
MicroTech 4 controls, Daikin applied rooftop systems can
be equipped with a remote user interface that handles up to
eight units per interface. The remote user interface provides
convenient access to unit diagnostics and control adjustments,
without having to access your roof or mechanical rooms
located on each floor.
Each remote user interface offers the same functionality as its
unit-mounted counterpart, including:
• Push-and-roll navigation wheel with an 8-line by 30
character display format.
• Digital display of messages in English language.
• All operating conditions, system alarms, control
parameters and schedules are monitored.
Features
• Can be wired up to 700 meters from units for flexibility in
placing each remote user interface within your building.
• Unit and remote user interfaces are both active.
