Do I have advanced wiring? (Generation 2)

 

 Video Note

Please note, Master Valves should only be wired to the "M" and "C" terminals.

Our navigation has changed within the app. To edit your advanced wiring, see the instructions below.

What is advanced wiring?

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 ("More" tab > "Controller Settings" > "Advanced Wiring (M Terminal)" > "Master Valve"). Please note, Master Valves should only be wired to the "M" and "C" terminals. 

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 ("More" tab > "Controller Settings" >"Advanced Wiring (M Terminal)" > "Well or Pump Start Relay").

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.

How an Indexing Valve works

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 and 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 ("More" tab > "Controller Settings" > "Advanced Wiring (M Terminal)" > "Master Valve").

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

Rain Sensor Wiring

Rain sensors normally have a fairly basic wiring setup. If you are unsure about how to setup your rain sensor with the Rachio, or if you have a more complicated rain sensor (such as wireless) please click here.
