Overview and specifications
™
The Tracer AH540 and the Tracer AH541 air-handler controllers pro-
vide digital control for a variety of constant-volume and variable-air-vol-
ume (VAV) air-handling units that conform to the LonMark
Comfort Controller (SCC) profile or the Discharge Air Controller (DAC)
profile. The Tracer AH541 is available in several models for field installa-
tion (BAS-PRC013-EN describes them). The Tracer AH540 controller is
available installed, pre-wired, and tested with the following Trane air-
handling units:
Packaged Climate Changer
•
M-Series Climate Changer air-handling unit
•
T-Series Climate Changer air-handling unit
•
The functionality of the factory-installed Tracer AH540 controller is iden-
tical to that of the field-installed Tracer AH541 controller. This document
refers to both versions of the controller as "the Tracer AH540/541" or "the
controller" unless a distinction needs to be made between the two.
Note:
This manual applies to Version 2 of the Tracer AH540/541 con-
troller. Both hardware and functional differences exist between
Version 1 and Version 2. Version 2 hardware has four additional
binary outputs and a universal analog input. These hardware
additions support Version 2 functions, which include all of those
inVersion 1 plus DX cooling, electric heat, dehumidification,
and two-pipe changeover.
