Response delay has the following effects:

When the value of the trip point is out of range (exceeded or not reached) for a period
of time longer than the delay time, the relay switches.

When the value of the trip point ± hysteresis is in range (not reached or exceeded) for a
period of time longer than the delay time, the relay switches back.

Shorter overranges/underranges do not have an effect.
The following illustration shows an example of switching characteristics with response delay
