## Overview

The JBL Protemp Coolcontrol Thermometer is a precision 12V DC thermostat designed for aquarium coolers, automatically regulating water temperature between 18°C and 36°C. Featuring easy installation with a temperature sensor and suction cup, it offers Auto, Manual, and OFF modes to maintain optimal aquatic conditions, protecting fish and plants from heat stress while ensuring energy-efficient operation.

## Description

12V Control Thermostat for Aquarium Coolers Temperature Control Two important factors influence water temperature. On the one hand the ambient temperature, on the other hand the radiation of the sun. When the room temperature rises sharply in summer, it is important to regularly control the temperature in the aquarium. The desirable temperature is between 24 and 26 ° C. Temperatures above 30 ° C are very problematic and can cause great harm to fish and plants. On the other hand, aquariums should never be directly exposed to sunlight. The higher the temperature, the harder the oxygen vital to animals diffuse into the water.

Review: lo que mas me ha gustado es el provecho sacado al tamaño del item versus el rendimiento. lo que menos me ha gustado es que entiendo que produce cierto ruido al funcionar
Review: I use a JBL Cooler 300 on my 29ga tall freshwater tank which is located on the second floor. During the summer it CA, it can get overly warm. The cooler helps to minimize that. After several years, I noticed the controller plug into the cooler was getting frayed and interrupting power to the unit. Replacing the controller fixed the problem. I’m glad I didn’t need to buy a new unit.

*by T***S on 28 June 2021*

Da leider die JBL Kühler extrem laut sind, steuere ich mit dem Gerät den Hobby Aqua Cooler V4. Die Spannung vom Hobby ist die gleiche, wie von den JBL Lüftern. Bei analogen Drehreglern ist natürlich die Temperaturposition nicht unbedingt stimmig, also einfach mit einem Laborthermometer die Wassertemperatur messen. Dann Automatik einschalten, den Drehregler nach oben drehen (sodass der Ventilator läuft) und beobachten, wie die Wassertemperatur nach einiger Zeit fällt. Ist die gewünschte Minimaltemperatur erreicht (wann er ausschalten soll), gaaaaanz vorsichtig und langsam das Drehrad zurückdrehen, bis der Ventilator abschaltet. Von jetzt an funktioniert es perfekt vollautomatisch. Der Ventilator schaltet sich immer von selbst ein, wenn die gemessene Temperatur 1 Grad höher ist, als die Abschalttemperatur. Also, wenn er bei 24 Grad abschaltet, schaltet er bei 25 Grad ein und kühlt 1 Grad herunter.
