RAIN BIRD ESP-TM2 OUTDOOR CONTROLLERS LNK WIFI COMPATIBLE

Rain Bird ESP-TM2 Outdoor Controllers provide local dial and button programming for residential garden reticulation and light commercial irrigation. The range includes fixed 4, 6, 8 and 12 station models. Each has a separate master-valve / pump-start circuit.

The ESP-TM2 provides 3 independent programs with 4 start times per program and station run times from 1 minute to 6 hours. Choose days of the week, odd/even calendar dates or a watering interval from 1 to 30 days. Station capacity is fixed, so choose the model for the number of zones required.

Add the optional LNK2 Wi-Fi module for Rain Bird app control, remote access and automatic weather-based seasonal adjustment. A suitable 2.4GHz Wi-Fi network and internet connection are required for online functions. The controller can still be programmed locally using its dial and buttons. LNK2 is sold separately.

Bluetooth assists LNK2 setup. For nearby app access without a site internet connection, connect to the module’s Wi-Fi hotspot. This local connection is separate from remote access when away from the property.

Seasonal adjustment changes station run times by percentage, either across all programs or for an individual program. Delay Watering can suspend eligible scheduled watering for up to 14 days. Permanent Days Off can exclude selected weekdays from odd/even or cyclic schedules.

A compatible rain or rain/freeze sensor can stop scheduled watering. Sensor bypass is available globally or by station. Delay Watering also follows the station’s sensor-bypass setting, so stations set to ignore the sensor can continue watering during a delay.

Manual watering can run a station, a program or a test of all stations. The controller supports one 24VAC irrigation solenoid per station plus a master valve or pump-start relay. The master-valve output can be enabled or disabled by station, and an adjustable delay between stations provides further control.

The outdoor cabinet is weather-resistant and rated IP24. A backlit LCD assists local programming. Automatic short detection reports the affected station. Non-volatile memory retains the schedule, an internal lithium battery maintains the clock during outages, and Contractor Default lets you save and restore a schedule backup. AC power is required to operate the valves.

3 Year Rain Bird Trade Warranty.

How watering programs work

The ESP-TM2 has three separate watering programs, labelled A, B and C. Each program is its own schedule, with separate watering days, start times and station run times.

Each station controls a watering zone, such as a lawn or garden bed. Within each program, choose which stations will water and set how long each runs. Run times range from 1 minute to 6 hours.

Each program allows up to four start times on its selected watering days. One start time begins the whole program. The controller waters its stations one after another for their set run times.

For example, Program A could start at 6am, water the lawn for 10 minutes, then water a garden bed for 5 minutes. That needs one start time. Add another start time to repeat the same sequence later that day. Programs B and C can have different schedules. Use only the programs and start times you need.

Avoiding common programming mistakes

• Avoid unintended repeat cycles. One start time runs the whole program. Each extra start repeats it. Turn unused start times OFF.
• Check all programs. A station included in more than one active program can water again under each schedule. Use multiple programs for the same station only when that extra watering is intended.
• Allow time for the whole watering cycle. Overlapping start times are queued rather than running stations together. A later cycle can therefore finish later than expected. Allow for every station, seasonal adjustment and any delay between stations when spacing starts.
