  • 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 requires its own controller.

  • Can CoolControl also control the new ProTemp Cooler x200 and x300 (Gen2)?

    Yes, the CoolControl from the previous series can also control the new ProTemp Cooler x200 and x300 (Gen 2) aquarium coolers.

  • Is rattling noise normal during operation?

    The roller turbine ensures an audible air flow that is even and should not rattle or clatter. If such a problem occurs, this could indicate damage caused by a fall or heavy impact on the housing wall. Check that the roller turbine is correctly positioned and that the housing is properly assembled. If this is not the case, your ProTemp Cooler must be returned to the factory for inspection and repair via JBL Customer Service.

  • The ProTemp Cooler X is too loud when running. What is the cause of this?

    The roller turbine of the Cooler 200X or 300X conveys a large amount of air to ensure sufficient evaporation on the water surface and thus cooling. As with a room fan, this is not possible without noise, but it is quiet. To ensure quiet operation, the turbine is mounted on a ball bearing for smooth running. If loud noises occur during operation, please check the attachment to the aquarium rim/base. The vibrations are probably being transmitted to the base and can be eliminated by making small adjustments. If you notice strong vibrations on the housing, this can be remedied by turning the housing.

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

    Yes, because the test strip continues to react. This means that a strip can only be used once. Repeated measurements will produce different values, as these change significantly after 70+ seconds. Please note that the chlorine value must be read immediately 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).
