That's basically the heater reaching it's set temperature by you when choosing a setting from 1 to 6 on the control
dial.  There is a point at which the thermocouple gets to a resistance value and the relay turns off.  I don't think it
has a range (eg. shut off at 24Kohm and turn on at 22Kohm) and therefore this clicking at the one point.  Nothing you
can do about that except go to a higher or lower setting.
My thermocouple failed completely (very common) and I replaced it with a single value resistance (about 13Kohm).
This way the relay always thinks the seat is cold and gives a constant uninterrupted current.
You do loose the safety feature but I am sure you are going to switch it off before your butt turns to well done bacon
