K-Rain 2520 Single-Station Pump Controller 220VAC — Rainswitch-Ready, 2 HP Relay

This compact, weather-tolerant controller is designed for simple, reliable irrigation or pump control where a single zone or pump must be coordinated with a rainswitch. It accepts 220 VAC power and provides a matching 220 VAC output to control up to a 2 horsepower motor through a double-pole single-throw relay. The 2520 model specifically supports simultaneous connection of a low-voltage (24 VAC) rain sensor and a high-voltage 220 VAC pump, allowing unified control from one enclosure. All models in the 2500 Series carry UL approval for safety compliance.

How does the 2520 handle a rain sensor and a high-voltage pump at the same time?

The 2520 is wired to accept a 24 VAC rain switch input while switching 220 VAC power to a pump. This separation of low-voltage sensing and high-voltage switching keeps circuits isolated but controlled from the same unit, simplifying installation.

• Allows connection of 24 VAC rain switch and 220 VAC pump simultaneously
• Internal wiring isolates sensor circuit from pump power
• Single-station layout reduces enclosure and conduit requirements

What power and motor capacity does the controller support?

The controller uses 220 VAC for both input and switched output and includes a relay rated to drive motors up to 2 horsepower. Its double-pole single-throw relay provides full disconnection of both legs of the 220 VAC feed for safer motor switching.

• Input: 220 VAC, 60 Hz; Output: 220 VAC, 60 Hz
• Relay rated up to 2 HP for direct pump control
• Double-pole, single-throw design disconnects both hot legs

Can I override the rain switch from the controller face?

Yes — the 2520 includes a manual override that lets an operator bypass the rain switch function at the controller. This feature is useful for maintenance, testing, or temporary operation during dry periods without rewiring.

• Front-panel manual override for quick local control
• Allows testing and scheduled runs regardless of rain-sensor state
• No need to remove sensor wiring to operate the pump manually

Is the 2520 safe and compliant for commercial or residential use?

The 2520 meets industry safety standards and is UL approved, making it suitable for a variety of irrigation and pump control installations in commercial and residential settings. Its compact, single-station design reduces wiring complexity while delivering industrial-strength switching capability.

• UL approved for recognized safety and reliability
• Industrial-duty relay supports common pump sizes up to 2 HP
• Simple single-station layout minimizes installation time

Who is this for? The K-Rain 2520 is intended for installers, landscapers, and property owners who need a rugged, single-station controller that can manage a 220 VAC pump while integrating a 24 VAC rain sensor. It’s ideal where compact control, a manual rain-switch override, and the ability to drive motors up to 2 HP are required — for example, small to medium irrigation pump systems, well pumps serving a single zone, or retrofit projects replacing older single-station controllers. If you need multi-zone scheduling or networked smart control, consider multi-station or smart controllers; if you need a straightforward, UL-approved single-station solution with rainswitch compatibility, the 2520 fits the bill.
