Hydraulic Indexing Valve Wiring
Indexing valves offer a central hub to automate multiple zoned
irrigation systems. Usually consisting of 1 inlet and 3+ outlets,
indexing valves can operate on city water or pumps.
An indexing valve will water on a zone by zone basis, diverting the
water supply from one outlet to another in a rotational direction.
The order of the zones cannot be changed on an indexing valve
are are predetermined by the order in which they were installed.
For more information, please visit rachio.com/indexing.
Install in the “M” terminal slot, and enable the Master Valve from
the device settings under Advanced within the Rachio App.
If your system’s water supply comes from city water, install
following the Master Valve wiring instructions, page 29.
Since the Rachio controller outputs 24VAC, a pump start relay is
required when using a pump with an Indexing valve (See page 30).
