ERROR MESSAGES
Before seeking Technical assistance, follow the steps of this table to check whether it is needed.
ERROR (Code) Description Cause/Solution
Er01 – FLOW
(During the
check up is not
not an error)
Flowmeter doesn’t work.
✓ Lack of flow on the circuit. Water circulator
disconnected or filter obstructed. Check electrical
connections of the circulator or clean filter.
✓
Poorly drained circuit. Excess air at the hydraulic
installation.
✓
Water flow too low. Increase water circulation pump
speed or replace for a larger one.
✓
Hydraulic circuit is empty (no water).
Er02 – TN Safety Thermostat
✓
Thermal relay action resulting from exaggerated
electrical consumption of the compressor or mains
voltage anomalies.
Er03 – LP
Low Pressure, system
doesn’t work or
disconnects cyclically
✓
Lack of fluid or leak on circuit. Check the circuit
pressure with gauge.
✓ Low outsider temperature.
✓
Obstruction of refrigerant circuit (e.g. Humidity).
✓ Low pressure switch damaged.
Er04 – HP
High pressure, system
doesn’t work
✓
Fluid overcharge. Check circuit pressure with
manometers.
✓ High pressure switch damaged.
✓
Poor heat exchange. Increase flow.
Er05 – TS1
Temperature alarm
✓
Excess of temperature. Lack of water in the circuit,
circulator pump disconnected or stuck or damaged
Flowmeter.
Er05 – TS2
Er06 – TS3
Er07 – TS4
Er08 – RTC Clock
✓
Internal clock of the controller is damaged. Replace
the controller.
✓ The controller battery is discharged or weak. Replace
the battery (type of battery CR2032)
TL
Probe Failure (S1, S2, S3
or S4)
✓
Check whether the probe is measuring correctly,
verifying its internal resistance.
✓
Verify connections.
Er11 - EVD
Alarm Relay Open on
Carel EVD
✓
Check the power supply on the EVD (fuse-Fs).
✓ Pressure/Temperature sensor connected wrongly or
damaged. Check connections or replace sensor (POS)
✓ Low Superheating (LowSH).
✓
Very low evaporation temperature (LOP).
✓
Very high evaporation temperature (MOP).
✓
Low aspiration temperature.
✓
Low aspiration pressure.
