Unisab lll, master/slave problem

Hi all,

I am servicing a plant with two SAB 233 E screws.
They are controlled by a Unisab lll each.

My problem is, that when the master is running 100% the slave starts its "pause before starting" timer, it will only stop counting if the master decreases to 95% capacity.
I only want the slave to be counted in when the master is running 100% and the temperature is above the neutral zone.
I have been looking at the parameters and cannot find anywhere to control this.

Does anybody have a solution to this problem.

Regards,
Peter
