Connection Points:

24VAC Input: Connect the 24 VAC control wires from your sprinkler controller to the designated 24VAC terminals on the relay.
Power In (L1 IN, L2 IN): Connect the incoming power supply wires to the L1 IN and L2 IN terminals.
Power Out (L1 OUT, L2 OUT): Connect the power wires leading to your pump to the L1 OUT and L2 OUT terminals.

Sample Layout:

Operating Instructions

Once installed and wired correctly, the Briidea Pump Start Relay operates automatically in conjunction with your sprinkler controller.

Ensure the main power supply to the pump and the sprinkler controller is restored.
When your sprinkler controller initiates a watering cycle, it sends a 24 VAC signal to the pump start relay.
Upon receiving this signal, the relay closes its internal contacts, allowing power to flow to the connected pump.
The pump will then activate and supply water to your sprinkler system.
When the sprinkler controller completes the watering cycle and stops sending the 24 VAC signal, the relay opens its contacts, cutting power to the pump and turning it off.

No manual intervention is required for the relay's operation once properly configured with your sprinkler system.

Maintenance

The Briidea Pump Start Relay is designed for minimal maintenance. Follow these guidelines to ensure long-term performance:

Periodically inspect the unit for any signs of physical damage or wear.
Ensure the enclosure lid remains tightly sealed to protect internal components from moisture and debris.
Check wire connections for tightness, especially after initial installation or if the unit has been moved.
Keep the area around the relay clear of obstructions to allow for proper ventilation and access.

Always disconnect power before performing any inspection or maintenance.

Troubleshooting

Problem	Possible Cause	Solution
Pump does not turn on when sprinkler controller activates.	No 24 VAC signal from controller. Loose or incorrect wiring. Pump power supply issue. Faulty relay.	Verify sprinkler controller is functioning and sending 24 VAC. Check all wiring connections against the diagram in the "Setup and Installation" section. Ensure wires are securely seated in lever-nut connectors. Confirm pump has power and is operational independently. If all other checks fail, the relay may be faulty and require replacement.
Pump runs continuously.	Continuous 24 VAC signal from controller. Relay contacts stuck closed.	Check sprinkler controller for continuous 24 VAC output. Disconnect 24 VAC input to the relay. If the pump still runs, the relay is likely faulty and needs replacement.
Unit shows signs of electrical issues (e.g., scorching, tripping breaker).	Incorrect wiring. Overload or short circuit. Internal component failure.	Immediately disconnect all power. Review wiring carefully against the diagram. Consult a qualified electrician. Do not attempt to operate if damage is visible.
