RTU-MP Controller 13
Virtual BACview
Virtual BACview is a freeware software application that mimics the BACview6 Handheld. The USB Link cable
(USB-L) is required to connect a computer to the RTU-MP board. The USB Link cable connects a PC's USB port
to the J12 local access port on the RTU-MP. This program functions and operates identical to the BACview
Handheld.
Sequence of operation
The RTU-MP will control the compressor, economizer, and heating outputs based on its own space
temperature input and setpoints. An optional CO2 IAQ sensor mounted in the space can influence the
economizer minimum position.
The RTU-MP has its own hardware clock that is set automatically when the software is installed on the board.
The default is to control to occupied setpoints all the time, until a type of occupancy control is set. Occupancy
types are described in the scheduling section.
The following sections describe the operation for the functions of the RTU-MP. All point objects that are
referred to in this sequence will be in reference to the objects, as viewed in BACview6 Handheld.
Scheduling
Scheduling is used to start heating or cooling (become occupied), based upon a day of the week and a time
period and control to the occupied heating or cooling setpoints. Scheduling functions are located under
occupancy determination and the schedule menu accessed by the Menu softkey. Your local time and date
should be set for these functions to operate properly.
