The TORO RD-12 MOD-R is the replacement module component for the Rain-Dial series irrigation controller, providing 12-station scheduling capability in a modular form factor. This unit is the controller module only, designed to slot into a compatible Rain-Dial enclosure or base unit rather than serving as a standalone controller. It handles zone timing and programming for up to 12 irrigation stations, making it a targeted replacement part for service technicians and irrigation professionals maintaining existing Rain-Dial installations.
This module is suited for residential and light commercial irrigation systems already built around the Rain-Dial platform. When the programming module fails or becomes damaged while the enclosure and field wiring remain intact, replacing only the module avoids a full controller changeout. Irrigation contractors and landscape maintenance professionals typically source this part for existing system repairs rather than new installations.
Designed as a module-only replacement component for Rain-Dial series irrigation controllers that support a 12-station modular configuration. No additional compatible model numbers were specified in the product data.
Installation should be performed by a qualified irrigation technician or licensed contractor. Disconnect power to the controller at the transformer or circuit breaker before removing the existing module or handling any wiring connections. Follow the Rain-Dial system documentation for module seating and zone terminal assignments. Verify all station wiring connections are secure before restoring power and running a test cycle.
