Thank you in advance for any input on this topic.
I had an old timer that was giving me issues on my irrigation system and decided to switch to a new digital timer. The old system is as follows:
Timer: Intermatic
http://www.amazon.com/Intermatic-T101-Hour-Dial-Timer/dp/B00002N5FN
Valve: 4 zone cycle
Pump: 1 HP - OLD no make or model on pump.
I noticed that within the mechanical timer there was a "pump start relay" within the case, and because I was able to remove the "Timer" components and it was a perfectly fine weatherproof case...I decided to see if I could utilize the pump start relay components with my new system.
New system is as follows:
Timer: Rainbird STPi 400

Valves: Orbit 3 Valve Inline Manifold Assembly

**Current Status:
I have installed all necessary wiring...plumbed all the valves...hooked up the wiring..etc..
When I activate a zone (3 zones total in system) I can hear the valve activating but my pump is not kicking on.
I have attached the common wire and MV/PS wire to the additional two leads on the relay as shown in this diagram..

I am at 120 V on terminals L1 and L2 (IN) and at 0 V at L1 and L2 (OUT)...and when I put the meter on the 24V areas from the diagram...I am getting just that 24 V.
I have basically narrowed it down to the pump relay being inadequate for whatever reason for the digital timer...I guess I am looking for an answer on additional wiring that I may need to do...or am I going to have to replace the pump relay with a different model specifically designed for use with digital timers. If I do have to replace with different...suggestions on make/model and where to buy would be greatly appreciated.
