I was able to resolve the problem. The problem lies within your init library, where you initialise the gpio pins for the relays. There seems to be a missing parameter on line 188:

GPIO.setup(self.pin, GPIO.OUT, initial=0)

the initial=0 parameter was missing which determines the startup state of the pins which controls the relays.
