  • What are the correct sector settings and nozzle settings for Turbo-Driven Pop-Up Sprinklers?

    With the Turbo-Driven Pop-Up Sprinklers 200 and 380 the jet rotates backwards and forwards in a circle. The pop-up sprinkler rotates backwards and forwards with the same speed both with smaller sectors or angles, e.g. 90? and with larger sectors, e.g.360?.
    To achieve a uniform sprinkling density on a lawn with several simultaneously operating pop-up sprinklers, the sprinklers with a large angle, e.g. 360? require nozzles with a greater output.
    Reason: Within a given time, a pop-up sprinkler with the small angle e.g. 90? covers a square metre of lawn with its oscillating jet more often than one with a large angle.
    Because of this, the pop-up sprinkler includes 4 nozzles with different water consumption. These should be adjusted according to the operating instructions or the packaging.
    Technically, these pop-up sprinklers could sprinkle each sector with each of the 4 different nozzles.
    T 380 nozzle adjustment: For this, the cover must be removed (central screw). Then the range adjustment mechanism is held with one hand and the nozzle selector disc is turned with the other hand until the required nozzle is in the range adjustment mechanism.

  • How do you adjust the TVR 50?

    To adjust the TVR 50 (e.g. to a 90? quarter-circle) proceed as follows:
    1. Pull the sprinkler head out of the well
    2. Hold the lower, grey piston with one hand,
    3. Turn the orange adjusting sleeve with the other hand until the white line aligns with the white line on the grey piston between 360? and 180? (= 90? setting)
    4. Let go of the orange adjustment sleeve,
    5. The spray direction is now in the region between the two triangular arrows
    6. By turning the grey piston (a cracking noise is normal when doing this) the spray direction can be rotated in the required direction.

  • What are the technical details for this water controller?

    The controller requires a 230 V connection. The 9 V alkaline battery is used for protection against power failure. The controller is protected against splashed water and is frost-proof. However, the battery must be removed before the start of the winter period.

  • Can the flow rate be completely shut off?

    No, The sprinkler can only be reduced to a very small flow by means of the flow regulator.

  • Can the Soaker Hose be repaired, branched or fixed?

    The 13 mm connecting elements of the GARDENA Micro-Drip-Systems fit the hose: e.g. connectors, T-joints, plugs, pipe guides.

  • How does the switching mechanism of the pulse sprinkler work?

    The switching mechanism consists of magnetised plastic and replaces the previous mechanism, which was spring-operated. This increases reliability and reduces the force required for switching.

  • How does the rain sensor work? What are its technical data?

    It works according to an opto-electronic principle. The function can be checked with a resistance meter: If rain is registered = 56 Ohm; dry = 23 Mega Ohm. Reaction time for precipitation: a few seconds. Drying time: approx. 2 hours, depending on the weather. This sensor is not frost-proof. GARDENA control units only check the state of the sensor every 60 seconds in automatic mode.

  • How does the Moisture Sensor work?

    The moisture sensor functions according to an electro-thermal principle.
    The tip of the moisture sensor must be firmly pressed into the ground.
    The sensor heats the felt in the tip for 7 seconds every 10 minutes.
    This procedure measures the cooling time:
    Wet: = long cooling time
    Dry = short cooling time

  • Is the Moisture Sensor frost-proof?

    No. The Moisture Sensor must be stored in a dry, frost-free place.
