Error code:
P1
Reason:
Overvoltage or undervoltage protection has tripped
Cause:
n
Faulty supply voltage
n
Refrigerant low or cooling circuit blocked
n
Faulty control board
Check the power supply. Is the supply voltage
correct?
NO
Switch the unit off and have the power supply
checked/corrected.
YES
Check the electrical connections. Are they OK?
NO
Replace the electrical connections.
YES
Switch the power on and put the unit into
standby mode. Measure the voltage on the
board, at contacts "P" and "N". This should be
approx. 310V, 340V or 380V DC. Now start the
unit. The voltage between "P" and "N" should
now be between 220-400V. Is the correct
voltage applied?
NO
Replace the control board.
YES
Check the transformer. Is a defect present?
NO
Replace the control board.
YES
Replace the transformer.
