## Description
The ESP-TM2 is Rain Bird's Extra Simple Programming residential controller. This 12-station indoor/outdoor cabinet is the conventional panel contractors already know how to hang, wire, and hand off — and it is LNK2-ready, so the same box becomes a Wi-Fi smart controller when the homeowner is ready.
Factory programming is three programs (A/B/C) with four start times per program. Station run times go from one minute up to six hours. Seasonal adjust scales a program from 5% to 200% without rewriting every station. Rain-sensor terminals are on the board; you can obey or bypass the sensor globally or per station.
This 12-zone SKU is the right pick for larger residential and light-commercial sites that do not need ME3 expansion. Station count is fixed — if the job may grow past 12 valves or needs flow, move to ESP-ME3 (modular to 22).
Add the LNK2WIFI module in the 5-pin accessory port and a Rain Bird rain sensor (WR2-48 is the usual pair) to meet EPA WaterSense weather-based controller criteria. The Rain Bird app is free. This shop is Big Irrigation Supply, not Rain Bird Corporation.

## FAQ
### Is the ESP-TM2 12-zone LNK2 compatible?

Yes. Every TM2 we sell is LNK Ready. Plug LNK2WIFI into the accessory port. Confirm the Wi-Fi / LNK Ready mark on the door — this line is not the older ESP-TM.

### Does TM2 include Wi-Fi?

No. Wi-Fi is the LNK2WIFI module. RC2 is the 8-zone SKU with Wi-Fi already in the cabinet.

### How do I get WaterSense on a TM2?

Add LNK2WIFI and a Rain Bird rain sensor (WR2-48 is the usual pair), then enable weather adjust in the Rain Bird app. Confirm the combination on your water district's list before you promise a rebate.

### Can I expand a TM2-12 later?

Station count is fixed. Move to a larger TM2 or to ESP-ME3 if you need more valves. ME3 is the path if you also want FG100 flow.
