  • Can I operate two coolers with one ProTemp CoolControl?

    The ProTemp CoolControl is connected between the power supply and the ProTemp Cooler. It is therefore not possible to connect two coolers to one controller. Each Cooler needs its own controller.

  • Can the CoolControl also regulate the new ProTemp Cooler x200 and x300 (generation 2)?

    Yes, the CoolControl of the predecessor range can also regulate the new ProTemp Cooler x200 and x300 (generation 2) aquarium coolers.

  • Is rattling normal during operation?

    The cross-flow fan provides an audible air flow that is uniform and must not rattle or clatter. However, if such a problem does occur, it could be an indication of damage from a fall or strong impacts on the enclosure wall. Check that the cross-flow fan is correctly mounted or if the housing is incorrectly assembled. If these are not the causes your ProTemp Cooler must be returned to the factory for inspection and repair by the JBL customer service.

  • The cooler does not cool down the aquarium

    JBL ProTemp Coolers cool the water temperature by 2-4 °C in high ambient temperatures. To achieve this with this product, it’s important the maximum recommended aquarium volume is adhered to. Please note that the cooling effect only occurs when the cooler is in operation and that the system needs to have been running continuously for a few hours beforehand. The air flow needs to be directed across the entire width of the aquarium and be at a 45° angle to the water surface. If only a part of the water surface is ventilated or the angle is set to 90°, the desired effect will be lost or greatly reduced. The housing can be rotated 360°.

  • Is it absolutely necessary to read the water test strips after 60 seconds?

    Yes, because the test strip will continue to react further. That’s why a strip can only be used once. A repeat measurement would result in different values, as these change considerably after 70+ seconds. Please note that the value for chlorine is to be read after a few seconds.

PUSH messages from JBL

What are PUSH messages? As part of the W3C standard, web notifications define an API for end-user notifications that are sent to the user's desktop and/or mobile devices via the browser. Notifications appear on the end devices as they are familiar to the end user from apps installed on the device (e.g. emails). Notifications appear on the end user’s device, just like an app (e.g. for emails) installed on the device.

A notification makes it possible to inform the user about an event outside the context of a website, such as a new blog post, a competition or a voucher.

These notifications enable a website operator to contact its users whenever they have a browser open - it doesn’t matter whether the user is currently visiting the website or not.

To be able to send web push notifications, all you need is a website with a web push code installed. This allows brands without apps to take advantage of many of the benefits of push notifications (personalised real-time communications at just the right moment).
