Controls Question

I need help. Licensed plumber/fitter helping a friend, not so good with controls.
I recently installed a Budderus G215 w/a Riello F10 burner.
The boiler came with what seems to be an adjustable Honeywell high limit control (no low limit adjustment)
The current setup has 5 zone valves (3 0n 1 circ) (2 on 1 circ) and a amtrol boilermate for domestic hot water.
The 3 zomes are tied into a circ relay that is then tied into the TT on the high limit, and also wired the aquastat of the boiler mate to the tt's on the high limit, and plan on installing another circ relay into the tt's on the high limit. It seems to me with the high limit only this is a cold start boiler that will only fire when something calls for heat when an end switch makes?
Do I need to change the primary controller or can I get this to work with what I have and if so how????

Any help or suggestions would be appreciated!!
