If you want to control multiple circulator pumps, we would recommend that you use a switching relay, such as a Taco SR504.
Well, not really. It's a voltage problem. Zone valves are 24 volt and that is what the output of this control module is. A Control set up to run circulators puts out 120VAC for each zone and if you have multiple circulators you need to get the right control.
Answer: No, Cannot handle the ampacity of the pumps.
I would just run the thermostat wire to the first actuator and then install jumpers to the second and third thermostat inputs. Sent from my iPhone
just wire them in parallel...each acutator has 2 wires that power the actuator and possibly 2 other wires for an "end switch" (but we're not talking about end switches right now)...if the acutator "load" wires are color coded then hook all of one color together which will receive the "heat call" (as well as the heat source, pumps etc) the other actuator wires (hooked together also) get hooked to the 24VAC common wire.
The priority feature is almost always used for an indirect water heater.
You would use the priority feature for a Domestic Hot water call. It would send the water exclusively to that zone, then when the demand is met, or a time limit is exceeded, it would fire the other zones. Rob _____
The priority feature is typically used for an indirect water heater. This way all the other zones turn off while the water is being heated to heat faster. Sent from my iPhone
When a priority zone "calls", all other zones' "calls" will be disregarded until the priority zone is satisfied. The priority zone is most often used for DHW (Domestic Hot Water) demands....the thinking being that the spacating will not suffer from a relatively short "off" period while the water heater is allowed to heat up.

The 3-year warranty is standard and applies to all Taco ZVC products without any extra fee. Please refer to the link below for more information. http://www.taco-hvac.com/products.html?view=warranty&warranty=16
It should be fine as long as they are low-voltage zone valves.
Yes, you can hook up four Taco 570 zone valves to this control.
No, you would need to use two ZVC404-EXP controls.
EXP models are expandable and allow you to add more zones to the control.
Normally, no more than three. The key factor is that you do not exceed the maximum allowable amp draw.
I recently completed an installation with 16 zones, in my home that I am building. I found that the 24V zone actuators that I am using pulled enough amperage that I was only able to run a single actuator on each zone (otherwise the TACO unit clicks on and then almost immediately clicks off). In some of my larger rooms, I have 3 separate loops with 3 separate zone actuators, so I ended up having to get several TACO zone valve control modules to give me the 16 zones I needed to drive the 16 actuators I have. For rooms with multiple loops I then jumpered the thermostat connections at the top of the circuit board, so only one thermostat would trigger the separate actuators (note: you can only jumper three thermostat sets, otherwise this will overload the transformer and it won't work).
No, these Taco Zone Valve Control Modules can only be used with low voltage thermostats.
