I'm replacing my Intermatic irrigation timer with a gen 1 rachio. I read that I needed a pump start relay in order to give my pump power but I am lost on how to wire everything. The instructions don't follow of what I have. I have two wires black and white coming from the circuit breaker (and a ground wire) and two black and white wires coming from the outside of the house from the pump. I know I need to connect a wire to the rachio but have no clue what type of wire to buy. I bought 18/2 wire but I only need 2 wires to connect to the rachio (common wire and the master valve wire).
Any help would be appreciated.
The pump replay I bought is an Orbit.
This is also an Indexing Valve system.
