lockout the compressor, and after the issue has been
resolved, it is necessary to manually reset the module
in order to clear the present alert code.
The primary way of clearing the code and resetting
the alert is to press the reset button located on the
module. Note: Pressing the reset will require a pin
or mini/electronics screwdriver. This button must be
pressed and held for a minimum of one second for the
module to be reset. Pressing the reset button clears
the immediate lock code and the seven day operating
history. It will not clear the permanent module history.
In the case of the three-wire module, the codes can be
reset or cleared by cycling power to the module. This
can be done by disengaging the Common (C) terminal.
This will not clear the seven day operating history.
Note: For the 571-0066-00 module, if a fault is present, it
is expected that the thermostat demand will remain
present and the module will stay powered and function
similar to the 571-0067-00 module. If the thermostat
demand cycles off, then the 571-0066-00 module will
reset and alert will clear.
