RESTMO Ball Valve Water Timer (Model DE-O-HTB-4A-GN) - Instruction Manual

Introduction

This manual provides detailed instructions for the setup, operation, and maintenance of your RESTMO Ball Valve Water Timer, Model DE-O-HTB-4A-GN. This electronic watering valve is designed to control garden irrigation efficiently, featuring a pressure-loss-free ball valve, two flexible watering programs, and a rain delay function. Please read this manual carefully before use to ensure optimal performance and longevity of your device.

Key Features

• Pressure-Loss-Free Ball Valve: Operates effectively across an ultra-wide water pressure range of 0 to 120 PSI (0-8.3 bar) without pressure loss, ensuring consistent water flow. Ideal for use with rain barrels and low-pressure water sources.
• Two Flexible Watering Programs: Offers two selectable watering intervals. Choose a high-frequency cycle (every 1 to 12 hours) for plants requiring frequent watering or an interval cycle (every 1 to 7 days) for plants with lower water needs. Watering duration is adjustable from 1 to 240 minutes.
• Water-Saving Rain Delay: Features three selectable rain delay modes: 24, 48, and 72 hours. This function allows you to pause watering with a single button press during rainfall, conserving water and preventing overwatering.
• Easy Operation: Equipped with a clear LCD screen for intuitive parameter adjustment. Rotary knob and buttons facilitate easy mode selection, making it user-friendly for all ages.
• Universal Connection: Standard 3/4" BSP thread fits most outdoor faucets and garden hoses. Tool-free installation, no additional parts required.

Setup

1. Battery Installation

The water timer requires two AA batteries (not included) for operation. These batteries typically provide power for approximately one year.

1. Locate the battery compartment on the back of the device.
2. Open the compartment cover.
3. Insert two new AA batteries, ensuring correct polarity (+/-).
4. Close the battery compartment cover securely.

2. Connecting the Water Timer

The timer features a standard 3/4" BSP thread for easy connection.

1. Ensure the faucet is turned off.
2. Screw the water timer onto your outdoor faucet. Hand-tighten only; do not overtighten.
3. Connect your garden hose to the outlet of the water timer.
4. Turn on the faucet. The ball valve design ensures no pressure loss, even with low-pressure sources like rain barrels.
