LARM CODES
The controller can detect certain errors and set off the alarm relay to
warn of the problem (to connect the relay, see the wiring diagram in-
cluded with this manual). The two probes and the potentiometer are
tested periodically to warn of errors. When a problem is detected, a
flashing code is displayed. The relay is activated one minute after the
alarm has been set off. The table below describes the alarm codes.
