Cause 2
No voltage on the control board.
Solution 2
Measure the supply voltage with a multimeter on the connections X1 of the
control board (A2).
Malfunction 2 Electric motor thermally stopped
Observation 2
The two LEDs D1 and D2 are on, during and after a shutdown of the motor for a
minimum of 2 minutes (blink code 1.3).
Cause 1
If the temperature in the electric motor becomes higher than 150 °C the system

Set the manual-control switch to position “0” to erase the error message. When
this occurs again and again or if the error message does not erase, contact your
supplier.
