•
Check the ambient probe connections
•
If the problem persists replace the probe
General magnetothermic circuit
breaker intervention.
•
Before reinserting the magnetothermic
circuit breaker please check that no short-
circuits are present. Reinsert then
magnetothermic circuit breaker verifying
all the absorptions to identify any
anomalies.
Auxiliary circuits
magnetothermic circuit breaker
intervention.
•
Before reinserting the magnetothermic
circuit breaker please check that no short-
circuits are present. Reinsert then
magnetothermic circuit breaker verifying
all the absorptions to identify any
anomalies.
Circuit protection fuse (on the
transformer) intervention.
•
Restore the fuse (Fusibile vetro 10X20
F250mA 250V) .
•
Check that transformer output absorption
not exceeding 0.25A.
•
Check that on clamps for Kriwan supply
no other users are connected.
•
Check that no short-circuits are present
on transformer output.
Compressor not starting
The panel is in stand-by mode
•
Check that panel is not in stand by mode
(blinking
green lamp). In that case
press the key to start the panel (fixed
green lamp)
Pressure switches or Kriwan
malfunctioning or their
intervention.
•
Check wirings, calibration and correct
working of compressor and sensors.
•
In case system is starting for the very first
time please check the presence of bridge
for Pump-Donw/Thermostat functioning
selection on X1 terminal block.
Make bridges on terminal block for the
enabling of devices not present in the
system (Kriwan, pressure switches)
No defrosting cycle is
made
Wrong setting of defrosting cycle
parameters
•
Check the correct setting of parameters.
