Why is my K-Rain RPS 46 turning on randomly?
If your K-Rain Irrigation System is coming on at random, the issue might be due to entering too many start times on the automatic programs. Review the number of start times entered on each program. If the programming is correct, the panel may need to be returned to the supplier or manufacturer.
What to do if my K-Rain RPS 46 Irrigation System doesn't start automatically?
If your K-Rain Irrigation System is not starting automatically, the issue could be due to incorrect programming or a blown fuse. If the unit operates manually, verify the programming. Also, check the fuse and field wiring.
Why is more than one station coming on at once on my K-Rain RPS 46 Irrigation System?
If more than one station on your K-Rain Irrigation System is coming on at once, it could be due to a damaged main output driver chip. Check the wiring and swap the faulty station wire(s) on the controller terminal block with a known working station wire. If the same outputs are still locked on, return the panel to the supplier/manufacturer.
What to do if buttons on keypad not responding on K-Rain Irrigation System?
If the buttons on the keypad of your K-Rain Irrigation System are not responding, it could be due to a short on the keypad or incorrect programming. Check the instruction book to ensure the programming is correct. If the keypad is still not responding, return the panel to the supplier or manufacturer.
Why does the fuse keep blowing in my K-Rain RPS 46 Irrigation System?
If the fuse keeps blowing in your K-Rain Irrigation System, it is likely due to incorrect or bad wiring connections. Check the wiring and connections to resolve this issue.
How to fix a single station not working on K-Rain Irrigation System?
If a single station on your K-Rain Irrigation System is not working, it may be due to a faulty solenoid coil. Swap the faulty station wire on the controller terminal block with a known working station wire. If the faulty valve still does not work on the known working connection, then the solenoid coil is faulty and the panel may need to be repaired.
Why is there no display on my K-Rain RPS 46 Irrigation System?
If there is no display on your K-Rain Irrigation System, it could be due to a faulty transformer or a blown fuse. Check the fuse, field wiring, and the transformer itself.
What causes pump start chattering in K-Rain RPS 46?
If your K-Rain Irrigation System pump start is chattering, it could be due to a faulty relay or pump contactor. An electrician should check the voltage on the pump relay or contactor.
What to do if K-Rain RPS 46 display is cracked?
If the display on your K-Rain Irrigation System is cracked or has missing segments, it's likely that the display was damaged during transportation. Return the panel to the supplier.
What to do if my K-Rain Irrigation System has no automatic start?
If your K-Rain Irrigation System operates manually but doesn't start automatically, the issue might stem from incorrect programming or a blown fuse. First, verify the programming settings. Then, inspect the fuse and field wiring.

The K-Rain RPS46 Mini Irrigation Controller is a versatile and user-friendly device designed for residential irrigation systems. It is available in 4 or 6 station configurations, making it suitable for various garden and turf area sizes. The controller features four separate programs, allowing for efficient watering of different zones, each with its own unique requirements. With a maximum of sixteen start times per day, it offers flexibility to cater to diverse watering needs, from pop-up sprinklers in turf areas requiring less frequent but heavier watering, to spray systems in flower beds needing more frequent watering.
The primary function of the K-Rain RPS46 is to automate irrigation schedules. It allows users to group stations (valves) with similar watering requirements into programs. For example, turf areas, flower beds, pergolas, undercover areas, or vegetable gardens can each have their own program. Once programmed, stations within a program will water sequentially from the lowest number at the nominated start time(s) on the selected days. Each station can be set to water for a maximum duration of 12 hours and 59 minutes.
The controller offers three types of watering day options:
An innovative "water saver" feature allows for quick adjustment of station watering times by a percentage, adapting to seasonal changes. This budget adjustment can be set in 25% increments from 25% to 150%, effectively reducing or increasing watering duration across all active programs.
The RPS46 also includes a rain sensor switch on the fascia. When enabled and the sensor detects rain, all automatic and manual watering cycles will be suspended, preventing overwatering and conserving water. This function can be manually overridden by switching the sensor to the "OFF" position.
For manual operations, the controller provides several options:
The controller also features "stacking start times," meaning if multiple programs are accidentally set with the same start time, they will run sequentially from the lowest program number, ensuring all programmed start times are eventually watered.
The K-Rain RPS46 is designed for ease of use with a clear LCD display and intuitive programming buttons. The selection dial is central to navigating operations and programming.
The RPS46 is an indoor model and must be installed in a protected area away from rain, water ingress, or direct sunlight. It should be mounted near a 120VAC outlet, preferably at eye level for ease of operation.
In the event of a power outage or if the 9-volt battery is not fitted or is low, the controller has a backup default program. This program waters every day at 12:00 a.m. for 10 minutes per station. A standard 9-volt battery should be fitted to the battery snap to maintain clock accuracy and preserve automatic programs during power outages. A "BAT" warning indicator will appear under the AM/PM indicator in clock mode when the battery is low or not fitted.
Servicing should always be performed by an authorized agent. The process involves:
The manual provides a troubleshooting guide for common issues:
The K-Rain RPS46 is a robust and feature-rich irrigation controller designed to provide reliable and efficient watering for residential landscapes, with a focus on user-friendly programming and water conservation.
