I don't know anything about love controllers at all, but I can read German and electrical diagrams pretty well. Are Love controllers actual PID devices? I thought they were a little different than a PID.
Anyway... the diagram on page 2 shows that K1 is a normally open (NO) relay. When the trigger event happens, the relay will close and make contact between those two pins.
K2 is a dual position relay. Pins 12 and 11 are normally closed (NC), meaning they are connected together by default. When the trigger event happens, this relay will open up and break the connection between pins 11 and 12. Simultaneously, as pins 11 and 12 disconnect, pins 11 and 14 will become connected. Pins 11 and 14 form another NO relay.
