Gas Combi Boiler Install-ZVC question

andymar Member Posts: 25
I had installed a Weil Mclain Aquabalance WMB-120 Combi gas boiler installed. My plumber installed two Honeywell 80431012 (4 wire) zone valves and one Taco 007-F5-71FC pump to supply two separate loops, circuits.. My questions are: Can someone recommend a compatible Zone Control Valve Module to use (Taco, Honeywell,...) and also a thermostat. I plan on using a Heat and Cooling thermostat for future A/C use. My boiler has an internal pump and is set up for outside reset. I assume the only connection I make to the boiler is wiring from the Module to the TT spots. The boiler plugs into a 110 outlet, I'm not certain whether there is a 24 volt transformer in the boiler, or whether that matters on not in choosing the Module (which I see has a transformer in it). Thank you.
