Trane's Digital Control System, AdaptAire, is designed to give the user the
ultimate in unit performance and operational flexibility, adaptability, and
reliability in a user-friendly package. The AdaptAire DDC system is a standard
component on Trane heating and cooling units. Non-recirculating units,
equipped with the AdaptAire system, do not have return air
capabilities, and all functions related to recirculating units are not
relevant. Where a function is similar but different between recirculating and
non-recirculating units, the function is explained separately.
AdaptAire accepts single or multiple units on the system network. Each unit can
be provided with a local user interface. The operating parameters for individual
units may be input through the local interface. A PC may also be connected to the
network. This allows the user to configure each unit separately, or all units can be
configured simultaneously. A controls contractor can provide assistance in
networking.
Operational modes include time scheduling, filter monitoring, and multiple
damper control and temperature control schemes. All of these modes provide
the maximum in unit operational flexibility.
The optional airflow station imparts unparalleled adaptability into the operation
of each unit. A daily self-calibration enables AdaptAire to detect the total air
volume and the exact ratio of outside and return air entering the unit. Then
AdaptAire daily fine-tunes the unit's operation based on these new parameters.
Air volume can vary because of changes in static pressure conditions due to
loading filters, VAV boxes, and building dynamics. These varying conditions
influence the ventilation air provided by the unit. On certain models of
recirculating direct-fired heaters this impacts the allowable equivalent
temperature rise of the unit that is allowed under the latest ANSI standard for
direct-fired heaters.
AdaptAire diagnostic capabilities insure swift response to abnormal unit
conditions. A fault is generated anytime the operational parameters and actual
unit operation are at odds. An indication of trouble is displayed at the local user
interface and system PC in text format. In the Diagnostics section of this manual
is a list of all faults and possible causes and solutions.
All of the features of the AdaptAire system are designed to provide the user with
real time information. At any time the user can display all of the operational
parameters, make changes, if necessary, and observe the various temperature,
pressure, and damper readings. The system's diagnostic capabilities provide the
user with up to the minute status reporting. (BACview service module or
WebCTRL internet connection is required for these features.)
