I think you should be able to use the Combi-Plan with two-bath Pyrocat. If it works with Diafine I think you should be ok with Pyrocat.
When I develop in tanks I agitate for a full minute at first in Solution A, and then for 15 seconds every minute thereafter. Be sure to add a few drops of Photoflo to Solution A. After finishing the time in Solution A drain for about 15 seconds.
I am not sure how you pour in the developer with a Combi-Plan, but if possible you need to remove the lid and pour in all of Solution B as quickly as possible. Then agitate continuously in Solution B for a minute, and for about 15 seconds every minute thereafter.
