In our new house we have 2 zones, one zone with 2 loops for the garage, and one zone with 6 loops for the house. Each loop is controlled by an actuator valve.
The garage zone works perfect, two actuators are wired back to the first zone.
The house zone only works with 4 loops (actual valves) wired back to the 2nd zone. Can Taco Zones only support 4 actuators per zone? Once we add more than four, any combination, it stops working for the house zone.
This was all installed by my plumber, so they are coming tomorrow to fix, but guessing they are going to need to install a taco control unit with another zone to support all the actuator valves?
Expertise/Help would be great, want to make sure this is done right.
