AXM Control
The Tranquility
®
Digital Air handler (TAH Revision B) is
equipped with a communicating AXM board to allow
communication with the communicating compressor section
(TES/TEP) and communicating thermostat (ATC).
The AXM control allows either 4-wire connection with
Communicating DXM2 board and Communicating
ATC Thermostat. It can also be connected to a non-
communicating thermostat and compressor section using
up to 9-wires (plus additional if functionality requires). Please
see Thermostat section for more details.
Low Air Temperature Sensor Installation
Tranquility
®
Digital Air Handlers are shipped with LT2 (Low
Air Temperature) sensor installed in the Air Handler (Figure
3) and connected to the AXM control. No additional action
required (do not clip the VIO wires).
Installation
Test Button
The test button puts the AXM into test mode, which
bypasses the soft start ramping profi le and the blower
immediately ramps up to the nominal target speed.
FIELD SELECTABLE INPUTS
DIP SWITCHES
Note: In the following fi eld confi guration options, DIP
switches should only be moved when power is removed
from the DXM2 Control to ensure proper operation.
DIP #2: Dehumidifi cation Mode - Provides selection of normal
or Dehumidifi cation Fan Mode. In Dehumidifi cation Mode, the
fan speed will be adjusted for Cooling. In Normal Mode, the
fan speed will be normal during Cooling.
On = Normal Fan Mode. Off = Dehumidifi cation Mode
Rest of the DIP switches are not used.
ACCESSORY CONNECTION / CONFIGURATION
2 Accessory outputs on AXM board only track blower
operation.
Other accessories are connected to the DXM2 board. Please
refer to DXM2 AOM for more details.
