Hi all can any one tell me how to reset a ATV 21 condensor inverter, without turning the power off,All the info I can find online is for stop and start but not reset, but this does not work.

Does the operation and programming guide help?

Hi Brian, no help in the user guides I downloaded, it says refer to CD supplied,no CD on site, it’s a pity it hasn’t got a reset button like on comp 1, I think I will just have to pull the power.

With the Keypad The STOP key can be used to clear a drive controller fault if:
Parameter CN0d is set to 1, and
Serial communication control has not been established
To clear a drive controller fault in keypad mode, press the STOP key. If it is
possible to reset the drive controller, the keypad will display CLr. To clear
the fault, press the STOP key a second time.
If the cause of the fault is still present, the CLr display will not appear.
Diagnose and solve the problem before attempting to reset the drive
controller.
The use of the STOP key as a fault reset can be disabled by setting
parameter F735 to 1.
