Do I have advanced wiring? (Generation 2)

On occasion, you might have more wires than zones. If that's the case, you might have advanced wiring that requires some extra attention and configuration:

Master Valve Wiring

A master valve is a “normally closed” valve installed at the supply point of the main line that opens whenever a zone is operating.

Install in the “M” terminal slot, and enable the Master Valve within the Rachio App (Device Settings > Advanced > Master Valve).

Pump Start Relay Wiring

A pump start relay serves as a switch that activates 110-220VAC power to the pump when the Rachio controller’s master valve is enabled. Since the Rachio controller outputs 24VAC, a pump start relay is required when using a pump with the Rachio controller.

CAUTION: In order to avoid potential damage from ELECTRICAL INTERFERENCE, relays should be installed at least 15 FEET away from the Rachio controller.

Install in the “M” terminal slot, and enable the Master Valve within the Rachio App (Device Settings > Advanced > Master Valve).

Make sure that the total draw of the Pump Start Relay plus the draw of the valve does not exceed 1.3 amps at 24 VAC, 60 Hz. The controller does not provide main power for a pump.

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 see this support article.

Install in the “M” terminal slot, and enable the Master Valve within the Rachio App (Device Settings > Advanced > Master Valve).

TIP: If your system’s water supply comes from city water, install following the Master Valve wiring instructions above. A pump start relay is required when using a pump with an Indexing valve.
