Table 7: Coax Water Pressure Drop
CXM/DXM2 Safety Control Reset - Lockout
- In
Lockout mode, the Status LED will begin fast flashing. The
compressor relay is turned off immediately. Lockout mode
can be soft reset via the thermostat “Y” input or can be
hard reset via the disconnect. The last fault causing the
lockout will be stored in memory and can be viewed by
going into test mode.
Fault Retry
- In Fault Retry mode, the Status LED begins
slow flashing to signal that the control is trying to recover
from a fault input. The CXM control will stage off the
outputs and then “try again” to satisfy the thermostat "Y"
input call. Once the thermostat input calls are satisfied,
the control will continue on as if no fault occurred. If 3
consecutive faults occur without satisfying the thermostat
"Y" input call, then the control will go to Lockout mode.
The last fault causing the lockout will be stored in memory
and can be viewed by going into test mode.
Consult the CXM AOM or DXM2 AOM for complete
descriptions.
