Hobby Biotherm Easy Control

Hobby Biotherm Easy Control – Automatically Keep Your Terrarium Climate Under Control

The Hobby Biotherm Easy Control performs three important functions in the terrarium: it controls temperature, humidity, and lighting. This means you don’t need multiple individual control units; instead, you can regulate the most important environmental parameters using a single, compact system.

The 40 preset species programs are especially convenient. Suitable settings are already programmed for many common terrarium animals, so you don’t have to adjust every setting yourself. Simply select the number corresponding to the appropriate species, set the current time and the desired start time, and the controller will take over from there.

At the same time, you remain flexible, since all important settings can also be adjusted manually. This makes the Biotherm Easy Control ideal both for beginners and for specific species and special breeding conditions.

Here are 10 common types that are already preset:

1. Bearded Dragon – Pogona vitticeps
2. Leopard Gecko – Eublepharis macularius
3. Corn Snake – Pantherophis guttatus
4. Royal Python – Python regius
5. Crowned Gecko – Correlophus ciliatus
6. Panther Chameleon – Furcifer pardalis
7. Yemeni chameleon – Chamaeleo calyptratus
8. Greek Tortoise – Testudo hermanni
9. Madagascar Day Gecko – Phelsuma spec.
10. Blue-tongued skink – Tiliqua spec.

Three functions in a single device

The Hobby Biotherm Easy Control operates with three separate channels, each of which performs a specific function.

Channel A functions as a timer and turns a connected load on and off at preset times. This makes this channel particularly well-suited for lighting.

Channel B controls the temperature and uses a modern PID control system. This allows the desired temperature to be maintained particularly evenly. In addition, different settings can be configured for day and night.

Channel C functions as a hygrostat and controls the humidity. For example, a sprinkler system or another suitable device can be automatically activated when the desired humidity level is to be reached.

This allows light, heat, and humidity to work together, while you control all the key areas using a single device.

Select an animal species and get started right away

Setting the correct climate parameters can quickly become complicated, especially with a new terrarium. That’s why the controller comes with 40 pre-programmed animal profiles, each with appropriate default settings.

Simply select the number corresponding to your pet’s species. Then set the current time in 24-hour format and the desired start time. The controller will then automatically apply the preset values for temperature, humidity, and lighting.

You can find a complete list of available types and numbers in the user manual and online.

Stable temperatures thanks to PID control

A special feature of the Hobby Biotherm Easy Control is its thermostat with PID control.

The temperature is precisely controlled so that the set value can be maintained as consistently as possible. This helps reduce significant fluctuations while creating a consistent indoor climate.

You can also set separate day and night temperatures. This way, the terrarium doesn’t stay at the same temperature around the clock; instead, you can simulate a natural daily cycle.

Automatically control humidity

You can also set the desired humidity level directly. The hygrostat monitors the set value and controls the connected device accordingly.

This means you don’t have to constantly check on things yourself or turn equipment on or off manually. Especially when it comes to tropical species or sensitive inhabitants, an automatic control system can make daily care much easier.

At the same time, you should ensure that the terrarium is properly ventilated so that, in addition to maintaining the right humidity, there is also good air circulation.

Turn the lights on and off automatically

You can use Channel A to control a device according to a fixed daily schedule. To do this, you set an on and off time, and the controller will then automatically turn the device on and off every day.

That is why this channel is particularly well-suited for LEDs and other terrarium lights. At the same time, it establishes a consistent day-night cycle, ensuring that animals and plants experience consistent conditions every day.

Pre-set, yet fully customizable

The 40 preset programs make it easy to get started, but you’re not locked into these settings permanently. Instead, you can adjust all the important settings yourself.

This means the Hobby Biotherm Easy Control can also be used for species not included in the preset programs. You can also adjust the settings specifically for breeding or for special conditions.

This way, the controller adapts to your needs as they grow, rather than limiting you to fixed programs.

Your settings will be saved

A power outage shouldn’t mean that you have to reset the entire terrarium afterward. That’s why the Hobby Biotherm Easy Control has a built-in memory function.

The saved settings are retained and are automatically restored after a power outage. This ensures that the control system continues to operate using the values you selected.

The easy-to-read display also shows you key operating parameters, so you can quickly check what’s happening in the terrarium.
