Well, the schematic is very difficult to read and I don't know the characteristics of the output line on the IR receiver, but the capacitor, in combination with the variable resistor, will slow down the response of the relay to either turning on or turning off, reducing chatter or excessive activations on spikes or noise from the receiver.

Hi guys,

Yes, that’s probably the intended purpose which makes it a lousy excuse for a well needed Schmitt trigger here. 8)
