CLEAR FAULT HISTORY

Clear Fault History will clear all fault codes stored in the
thermostat as well as the fault history in any connected
communicating controls (DXM2/AXM).
9.6 MULT-UNIT DIAGNOSTICS
If multiple units are connected to one thermostat when
Manual Operation, Control Diagnostics, or Dipstick
Confi guration is selected, the service personnel will see a
screen to select a specifi c unit by the last 4 digits of its serial
number.
NOTE: Multiple units may be connected directly to the ATC
thermostat or connected to one another in series, as shown by
the fi gure below.
