8 ERRORS
Symbols
Description
Problem / Checking
Er01 – S1
Anomaly
detected in probe
1
Damaged probe - Measure the probe's internal resistance
which at a temperature of 25ºC is approximately 10 KΩ.
Probe disconnected from the controller - Check that the
connector is securely connected to the electronic board
and/or that the connection terminals are tight.
Er02 – S2
Anomaly
detected
in probe 2,
when applicable
E03 – TA
Anomaly
detected in water
temperature
Water temperature in storage water heater is too hot –
Check that there is no anomaly in the electronic board, such
as a damaged relay.
Temperature probes in short-circuit – Measure internal
resistance of probe, it should be approximately 10 KΩ at the
temperature of 25ºC, check that the connector is well
attached to the electronic plate and the connection
terminals are in good condition.
Error “Lo”
Temperature
probe is
damaged or in
short-circuit
Check the connections of the temperature probe.
Replace with new probe.
LP
Protection
system is
activated
Check low pressure switch – Check if the connector is well
attached to the electronic plate and that the connection
terminals are secure, or that the pressure gauge is running.
Lack of refrigerant fluid in the circuit – Load of refrigerant
incomplete or leak. Low external temperature.
LINK
ERROR
Communication
failure
Connection cable between display and command panel
– Check the cable is in good condition or that the plugs are
correctly inserted (display and command panel).
