Biotherm Easy Control

The preset controller for stable terrarium conditions

The Biotherm Easy Control is a preset controller for precise control of temperature, humidity and lighting in terrariums.
It combines a timer, thermostat with modern PID control and hygrostat in one compact system and enables reliable, species-appropriate climate control without complex programming.
The controller has 40 common species stored with coordinated standard values.
A complete overview can be found in the instruction manual or online.
After selecting the appropriate number, simply set the current time in 24-hour format and define the desired start time.
From this point on, the controller automatically takes over the control of all connected components.
Temperature curves with separate day and night values, constant humidity and lighting times are automatically regulated and adapted to the selected animal species.
The internal structure operates via three clearly defined channels.
Channel A acts as a timer and controls a consumer with an adjustable ON and OFF period per day, for example, the lighting.
Channel B acts as a thermostat with precise PID control, regulating the temperature and ensuring particularly stable values.
Channel C functions as a hygrostat and maintains a defined humidity value. This clear system logic reduces technical hurdles and creates reliable conditions in the terrarium.
Despite the preset programmes, the controller remains completely flexible.
For special species, individual breeding conditions or special climate requirements, all parameters can be adjusted manually and tailored precisely to the needs of the animals being cared for.
The easy-to-read display provides information on all relevant values at all times.
An integrated memory function permanently stores all settings and automatically restores them after a power failure.
This keeps the terrarium climate stable and controllable at all times.

Highlights at a glance

40 preset species programmes
The Biotherm Easy Control has 40 stored animal profiles with coordinated standard values. This means that suitable climate parameters are immediately available for many common reptiles and amphibians.

Easy species selection by number
The desired animal species can be conveniently selected by number. After entering the current time in 24-hour format and setting the start time, the controller takes over complete control.

Automatic daily control
Temperature, humidity and lighting are coordinated and regulated throughout the day. This creates a stable, species-appropriate climate without complex programming.

PID-controlled temperature control
The integrated thermostat works with precise PID control. Day and night temperature values can be defined separately to realistically reflect natural fluctuations.

Constant humidity control
The integrated hygrostat reliably maintains a specified humidity value within the desired range. This ensures that even sensitive climate conditions remain stable at all times.

Integrated timer function
The timer function can be used to control a consumer with a defined ON and OFF period per day. This is ideal for lighting or other technical components.

Individually customisable
Despite the preset programmes, all parameters can be adjusted manually at any time. The controller thus remains flexible for special types or specific breeding requirements.

Clear display and memory function
The easy-to-read display provides information about all relevant operating values at all times. An integrated memory function automatically restores all saved settings after a power failure.
