6.0 ERRORS
6.1 E
RROR CODES AND POSSIBLE SOLUTIONS
The error codes are shown on the thermoregulator display and all start with the letter
E
, moreover the 11
LEDs of setpoint position (see paragraph
) start flashing.
In the presence of several errors, the error codes are summed up

Code
Type of malfunction
Type of necessary intervention
E 1
The internal temperature of the card is lower than
0°C.
Check that the ambient temperature is
within the thermoregulator operational
range, then restart the thermoregulator.
E 2
The internal temperature of the card is higher than
+80°C.
Check that the ambient temperature is
within the thermoregulator operational
range, then restart the thermoregulator.
E 4
The external temperature (temperature probe of
the oven) is in under range (lower than 0°C).
Check that the oven temperature is higher
than 0°C, otherwise the problem is as-
cribed to a malfunctioning of the
temperature probe connected with the
thermoregulator.
E 8
The external temperature (temperature probe of
the oven) is in over range.
Check that the oven temperature is lower
than the max temperature (see paragraph
), otherwise the problem is
ascribed to a malfunctioning of the
temperature probe connected with the
thermoregulator.
E16
The RTD temperature probe is not properly
connected.
Check that all the three connections of the
temperature probe (RTD) have been
properly made.
E32
Internal error (CRC) of the thermoregulator.
Internal error CRC of the card, a possible
cause may be an external disturbance
which has caused its malfunction, restart
the thermoregulator.
