Welcome to the Pump Start Relay support section.
The PSR is fully compatible with all standard 24VAC controllers.
Maximum Distance to Controller
The maximum distance of wire used from pump start relay to your irrigation controller (1) should never exceed the numbers listed in the chart below.
Minimum Distance to Controller
While most of the time the distance between the controller and pump start relay doesn't create any problems, every once in a while the wires on the 24V coil can allow
Connect To Power Source
NOTE: Connecting the Pump Start Relay should only be done by a licensed electrician following local codes. Improper installation could result in shock or fire hazard.
The PSR-B was developed to provide a solution for irrigation controller and pump start relays installations that have insufficient power to energize the pump relay. A common cause
REL 2 - Relay Installation Guide
REL 2 is used to allow multiple controllers to operate the same low-voltage device (Master Valve or Pump Start Relay). IMPORTANT: REL 2 is NEVER connected to high voltage.
The chattering you hear on a pump start relay is usually caused by insufficient amperage arriving at the relay from the controller. The first question you should ask yourself is –
