Normally R845As would be used for each circulator or there are panels that will handle 4 circulators.

I would put a 10 amp relay in and run the secondary pumps with it. You are close enough to the rating that it would be better safe than sorry. Besides, a relay is only $10, small money to pay compared to a L8124A.

The manual says the circulator circuit in the L8124a can handle 7.4 amps. You might overheat that relay on a long heat call...probably a good idea to put the 007's on their own relay.
