TROUBLESHOOTING
Disconnect the main power supply before any intervention to the unit. If you are not sure of the correct steps,
do not attempt to perform any repairs, and call a professional service!

Solution
Determine the cause of the overheating (defective
bearing, short-circuit...) or replace the motor.
Replace filters. After replacing, do not forget to reset the
MENU 1616 – FILTER TIMER
Check the heater and the condition of the safety
thermostat Does the heater have proper cooling?
Check engine running.
Check that the sensor is correctly connected to the
electronics or test it measuring its resistance (the
resistance value at +20°C is around 10kW)

Check that in the BMS that the address where the
sensors sends the data is properly set
(on the right regulator) Check the function of the sensor
in the BMS
Check that in the BMS that the address where the

(on the right regulator) Check the function of the sensor
in the BMS
The air flow settings were reduced, limiting the heater
output to prevent overheating
Check the communication cable for damages and if it
is properly connected Observe the wiring diagram to
prevent occurrences that may disrupt communication
(wiring near high tension, phenomena on site causing
disruptions)
Check that the power supply is not interrupted
Check the fuse in side the control module
The heater overheats due to insufficient air flow. Check
that the ventilators are in good order and that the air
supply is not disrupted.
