Number of stations: 6

Powered by batteries (2 x 1.5 V AA)

Ultrasonic-welded ABS body

Battery compartment with sealing OR

IP68 waterproof rating (totally submersible)

Controls latching solenoids Cable (red) for two-wire mechanical rain sensor connection

2. Technical Characteristics

Programming modes:

- By Program A, B and C (with 4 start times with weekly/monthly/by-cycle frequency)
- By Valve (fixed irrigation duration with 4 daily start times)
- By Valve Start Time (4 start times with independent watering durations)

3. Battery Installation

Unscrew the cap on the back of controller and install two AA type 1.5V batteries, taking care to follow the correct polarity.

NOTE: before closing the compartment, make sure the battery compartment is properly clean.

4. Solenoid Valves Connection

1. Cut off the quick couplings and strip around 15 mm of insulation from the ends of each cable.

2. Connect the black wires coming from each solenoid to the black cables coming from the controller. Secure all cable couplings with waterproof connectors.

3. Connect the red wires coming from each solenoid to the corresponding station wire (blue cable) coming from the controller. Station numbers are identified by the tag on the cable. Secure all cable couplings with waterproof connectors.

5. Rain Sensor Connection

A mechanical rain sensor can be connected to the TBD. Its purpose is to pause the irrigation when the rain falls down.
1. Cut off the red cable approximately halfway of the ring.
2. Strip around 15 mm of insulation from the ends of each cable. Connect both ends of the red cable to each one of the two rain sensor wires.
3. Use waterproof connectors to make cable couplings

Note: TBD is compatible with all rain sensors that work with “normally closed” contact.
