Brand: K-Rain SKU: 2520
Product Overview
The K-Rain 2520 is a rain-switch-ready mechanical controller for one compatible 220-volt irrigation load. It combines line-voltage pump control with terminals for a compatible 24-volt rain switch, allowing a pump-fed irrigation system to pause scheduled operation after sufficient rainfall without changing the timer program.
The controller accepts 220 VAC input and switches 220 VAC output for an approved motor load rated up to 2 horsepower. Its 24-hour dial supports multiple starts, and a retained-pin schedule provides repeating control across a 14-day cycle. The face-mounted rain-switch override gives the installer or property owner a controlled way to manage the sensor circuit when site conditions require manual intervention.
The 24-volt reference applies to the compatible rain-switch circuit—not to the main switched load. The 2520 does not function as a conventional 24 VAC multi-zone irrigation controller. The rain sensor is sold separately. Before installation, verify the supply voltage, motor nameplate, horsepower, switching requirements, wiring method, grounding, overcurrent protection, and local code requirements. Because this controller handles line voltage, installation and service should be completed by a qualified professional using the current K-Rain wiring instructions.

Compatibility and Installation Notes
- Confirm a 220 VAC supply and compatible load not exceeding 2 HP.
- The compatible 24V rain switch is not included.
- The main controller output remains 220 VAC; it is not a 24 VAC station output.
- Use required pump starters, overload devices, and disconnects where applicable.
- Follow the current K-Rain instructions and applicable electrical codes.
Frequently Asked Questions
Does the K-Rain 2520 output 24 volts to the pump?
No. It switches a 220 VAC load. The 24-volt specification refers to the compatible rain-switch circuit.
Is a rain/freeze sensor included?
No. This controller is sensor ready, but the compatible weather sensor is purchased separately.
Can it operate standard 24 VAC irrigation valves directly?
No. The 2520 is a single-load line-voltage controller rather than a conventional multi-station valve controller.
Why Buy This K-Rain 2520 from Big Frog Supply?
Big Frog Supply separates the 2520's 220V pump-control function from its 24V rain-switch compatibility so customers can match the correct timer without mistaking the sensor voltage for the switched-load voltage.
