argo az-6cp to arm-3p

hi, im looking for help wiring my az-6cp zone valve control to a arm-3p switch relay.i have six zones and three circulators. one circ for two zones

Does One Zone Need Priority?

If not, eliminate the AZ 6 Cp panel. Wire each T'stat directly to it's own zone valve and parallel the end switches for each pair of zone valves to the corresponding "TT" terminals on the ARM3 panel. In other words, zone valves 1 &2 will have their end switches connected in parallel to the "TT" terminals for circ.1 on the panel. Zone valves 3&4 will have their end switches paralleled to the "TT" terminals for circ. 2, etc. Connect each circ. to the corresponding high voltage terminals. Connect the boiler's "TT" terminals to "XX (end switch) on the ARM3 panel.
