Garmerain GWT101S - 1-Zone Water Timer

A reliable, easy-to-set-up water timer for a single irrigation zone — it automates watering in a garden, greenhouse, or on a balcony, so plants receive water regularly without manual intervention.

• Type: 1-zone digital water timer.
• Operating pressure: 0.5–8 bar (≈ 7–116 PSI).
• Maximum flow rate (throughput): up to 35 L/min.
• Watering duration: from 1 to 240 minutes (up to 4 hours).
• Watering frequency: every 1–12 hours or at intervals of 1–7 days — selected according to plant needs.
• Power supply: 2 × AA (1.5 V) batteries.
• Operating temperature range: 3 °C–50 °C.
• Valve / connections: standard threads for tap and hose.
• Low-battery indicator and frost protection — at temperatures below ~3 °C, the device should be removed to prevent damage.
• Operating modes: automatic (scheduled), manual watering (without changing the main schedule), and a "Rain-Delay" option (postponement in rain/high humidity).

Recommendations for use

• Install the timer on a standard garden tap or hose, before the pipe/hose leading to the plants.
• Set a schedule: choose a convenient start time, duration, and frequency — this allows regular watering without manual intervention.
• When you are away or have an unpredictable schedule, the timer ensures that plants receive water even when you are not there.
• For winter: remove the device if frost is expected — the water inside may freeze and damage the housing.
• Maintain normal pressure (0.5–8 bar) and good flow rate — excessively low or high pressure, or clogged filters, can disrupt watering.
