Universal board QD-U05PGC + PG terminal is live, still off

Good afternoon, I am installing this board in a split and testing it before placing it, I see that it always energizes me on the PG terminal (Interior fan), even if it is turned off. I still did not go to my client and wanted to save all my doubts before going. Is this normal? I will appreciate your opinions. thank you Paul

You are not sure you are wrong, the hall effect sensor is one thing and the voltage is another the voltage of the fan motor is 220vac and the hall effect works with 5VDC the function of connecting the three small wires of the hall effect is that this sensation or it measures the revolutions of the fan motor and when disconnected it does not feel them and the card sends the fan motor off by throwing the error

There I think I understood you.
By not testing it with the connected motor (both tabs) I will always have 220v on the PG terminal.
When the entire sensor is connected, it will give the order to interrupt the voltage at the PG terminal (board OFF), or send the corresponding voltage at each FAN speed (board ON).
I apologize if it is not.
I send you a hug and thanks for the stamina

When you make your connection to the universal card and the air is off you will always have an active line only one the other is activated when you turn on the card

Hello how are you? you will always be energized a line remember that the line you connect in the relay specifically where COM says when connected there is automatically energized VR which is the valve, OUT FAN and PG so be calm that it is normal. What if it would not be normal is that you turn it off and the fan motor will be on greetings and comment on how you are doing

Thanks for the prompt response.
Then if I did not use the Hall effect connector, the Fan turbine would be on. Do not?
And if I connect the hall effect token to the board, by not giving it a signal (board status: off), the Fan's turbine would turn off.
I don't know if I'm clear.
Thank you!!

Okay. I already tried it connected. The plate maintains 220v when energized until it feels a couple of turns of the fan. Then it goes to 0v.
It does as an initialization of the system.
Thank you
