I'm setting up a hydronic heating system using supply and return manifolds with 5 ports each.

There are actuators for the ports on the return manifold:

Was looking at the Taco 3 zone controller (https://www.tacocomfort.com/documents/FileLibrary/102-391.pdf).

I'd like to have a total of three zones, where Z1 controls two of the actuators, Z2 controls two of the actuators, and Z3 controls 1 actuator.

In order for one zone on the controller to operate two actuators, I'm wondering if I can simply splice the wires for two actuators together to be powered by the zone controller?

Looks like the actuators have a "max inrush current" of 250mA, so a total of 0.5A per zone with two actuators wired together.

According to the specs for the controller, it says, "All thermostat and zone valve connections supply a 24VAC class 2 output", which is 1amp @ 24V, correct? So if my max draw would be 0.5 amp per zone, with max total draw of all 5 @ 1.25A.

Looks like the controller is "24VAC per Zone 40VA Total". Is 40VA @ 24V 1.66A??
