21.5V instead of 24V on Wind and Status

Air Assist Not Working

Hi. I am trying to set up air assist on my Ruida RDC6445G controller. The solenoid is connected to +24V and the STATUS connector, nothing happens. I tried connecting it to the WIND connector and again nothing changed. The voltage on the connectors drops to +3V, but if you connect the solenoid to the +24V and GND connector, then it works. I found a post on the forum with a similar problem, but there was no solution in it, maybe someone can help me.
