Label Fault Cause E ects Remedy
E1
Probe 1 faulty
(cold room)
• measured values are outside
operating range
• probe faulty/short-circuited/open
• Display label E1
• Alarm icon permanently on
• Min/max alarm regulator disabled
• Compressor operation according to “Ont”
parameter.
• check probe type NTC/PTC (H00)
• check the probe wiring
• replace probe
E2
Probe 2 faulty
(defrost)
• measured values are outside
operating range
• probe faulty/short-circuited/open
• Display label E2
• Alarm icon permanently on

temperature
alarm
• value read by probe 1 > HAL after
time of “tAO”.
(see MAX/MIN ALARMS table)
• Recording of label AH1 in folder AL
• No e ect on regulation
• Wait until temperature value read
by probe 1 returns below HAL
