Compatibility & Installation Notes
Use with compatible 24 VAC irrigation valves; the manual specifies one valve solenoid per station terminal. Select a fixed station count that covers your system because this is not a station-expansion-module controller. Follow the manual for common, station, sensor and master-valve or pump-start-relay connections. The controller does not supply pump power. LNK2 and a compatible rain sensor are separate additions; do not assume a stand-alone controller includes weather-based control.
Frequently Asked Questions
Does the ESP-TM2 include WiFi?
No. Remote app control requires the separately sold Rain Bird LNK2 WiFi module.
Which zone counts are offered here?
This listing offers ESP-TM2-8 with eight fixed zones and ESP-TM2-12 with twelve fixed zones.
Can the controller be installed outdoors?
Yes. These North American indoor/outdoor models use a weather-resistant cabinet and 120V power supply.
Will it retain the schedule during a power outage?
Nonvolatile memory retains the watering program. An internal lithium battery maintains the clock and date; an external backup battery is not required.
Why Buy from Big Frog Supply?
Big Frog Supply maps both listed SKUs to their fixed 8- and 12-zone capacities and identifies LNK2 as a separate purchase, helping you size the controller and plan an optional WiFi upgrade together.
