Что означают ошибки P7, F4 - ?
Mentallist
Re: daikin vrv p7 fault
Hi, im assuming that you were commissioning a VRV III Heat Recovery system. On these systems the P7 error is generated when no automatic charging function has been completed, and you hold the test buttong to activate the full learning function (Test Operation).
If you do not charge the system using the automatic mode, you should activate the quick test by using mode 2, binary 3 setting, then you will not generate the error.
However if you do activate the full learning function rather then using mode 3, binary 3 it does not matter as the first 30 to 50 minutes of this operation is the same as the quick test, so by pressing the return button once when P7 is generated, the test will be cancelled and the P7 error will be removed.
If you look in some old error code sheets, it will give you the meaning of this code as "Total System Over Current", this is not the meaning of this code for VRV III systems.
