As it is seen above block diagram. 220V line is connected to the commons of comp relay, Ry 71 and defrosting heater relay, Ry 73, Ry 75. When those relays are off state comp and defrosting heater are also off. As comp relay moves to on and AC 220V applied to comp load it starts operating On the other hand defrost heater runs if defrost heater relay moves to on. There is no chance that both comp and defrost heater runs together so it’s useful for safety aspect.
