Hi,
I think that you could connect the switchoff delay block behind the B31 as you suggest or a simple gt/lt (greater than/less then - but this will not solve the hysteresis as the B31does).
As it is written in the documentation, X is the actual temperature from a sensor, W is the setpoint when the output will become True, Xp is the hysteresis - eg if set to 5, the out will become True once the teperature goes below 90-5=95 thus the relay will not switch that frequently. Take a look at the graph on the help file….
