Overview

The HOBBY Biotherm eco is a programmable temperature controller designed for use in enclosed rooms, specifically for aquariums and terrariums. It allows for precise temperature regulation and offers various programmable functions to create optimal environmental conditions for aquatic and reptilian life.

Function Description:

The core function of the Biotherm eco is to monitor and control the temperature of an external heating or cooling device connected to its integrated slot. It operates with a high degree of precision, regulating temperature within a range of 10 °C to 60 °C with an accuracy of 0.1 °C.

Key features include:

  • Function Monitoring of External Devices: An LED on the housing indicates when the external device (heater or cooler) is actively being controlled.
  • Safety Shutdown during Programming: For safety reasons, the output slot is deactivated when the device enters programming mode.
  • Safeguard Function: To protect electronic components, a 60-second delay is implemented between switching states before the slot becomes active again.
  • Return Function: If no button is pressed for 90 seconds while in programming mode, the device automatically reverts to operating mode.
  • Malfunction Displaying: In case of a sensor fault or short circuit, "E01" is displayed, and the heater is deactivated to prevent overheating. The manual recommends using submersion tube heaters with integrated thermostats and safety cut-out functions for added safety.
  • Clock Programming: The device allows for setting the current time (hours and minutes). The factory preset is 12:00, and this setting is retained even after a reset.
  • Choice of HEAT/COOL Mode: A convenient inversion function allows switching between "HEAT" and "COOL" modes. This enables the connection of either a heating device to increase temperature or a cooling device to counteract temperature increases.
  • Temperature Programming: Users can set a desired temperature between 10 °C and 60 °C with 0.1 °C precision.
  • Nocturnal Temperature Programming: This feature allows for programming two turn-on/turn-off times to simulate a natural temperature drop at night. Users can set the start and end times for the night period and specify a different desired temperature for this period. If no night time is programmed, the set temperature is maintained for 24 hours.
  • Temperature Alarm Setting: A visual alarm is triggered if the temperature deviates from the programmed desired value by a user-defined margin. An alarm window can be set between +/- 0.1 °C and 10 °C. The factory setting for the alarm is "00," meaning no alarm is set. For example, if the temperature is set to 25 °C and the alarm window is +/- 3 °C, an alarm will activate if the temperature drops below 22 °C or rises above 28 °C.

Important Technical Specifications:

  • Operating Voltage: 230 V, 50 Hz
  • Load Capacity: Max. 2,000 W (ohmic load)
  • Temperature Display Range: -9.9 °C to 99.9 °C
  • Temperature Control Range: 10 °C to 60 °C
  • Temperature Alarm Range: +/- 0.1 °C to 10 °C (00 means 'no alarm')
  • Temperature Display Accuracy: 0.1 °C
  • Temperature Control Accuracy: +/- 0.1 °C
  • Sensor Tolerance: +/- 0.5 °C
  • Sensor Cable Length: 3 m

Usage Features:

The Biotherm eco offers both "Single mode" and "Toggle mode" for display. In Single mode (factory preset), either the temperature or the current time is displayed continuously. In Toggle mode, temperature and time are displayed alternately every 2 seconds. Users can switch between these modes by pressing the "down" button.

Programming is initiated by pressing the "MENU" button. Navigation through menu items is done using the "up" and "down" buttons. To modify a value, the "MENU" button is pressed, causing the value to flash. The "up" and "down" buttons are then used to adjust the value, and "MENU" is pressed again to acknowledge.

Exiting programming mode happens automatically after 90 seconds of inactivity or by holding the "MENU" button for 3 seconds, saving all changes. Programming can be canceled at any time without saving by simultaneously pressing the "up" and "down" buttons.

Manual activation/deactivation of the slot is possible by holding the "up" button and then pressing "MENU." Pressing these buttons a second time deactivates the slot, and a third press reactivates program mode.

Maintenance Features:

In case of malfunction, a reset function is available. This involves unplugging the device, plugging it back in while holding the "MENU" button, and then releasing "MENU." It's important to note that a reset will erase all programmed settings except for the clock, reverting the device to factory presets.

The manual also provides a "Source of Fault" table, indicating that an "E01" display signifies a sensor fault or short circuit, requiring repair. For warranty or repair issues, the device should be returned to the place of purchase.

The device is designed for indoor use only, and contact with water should be avoided. It should not be modified, and covers or housings should not be opened. If damage is detected, the product should not be used and should be immediately disconnected from the mains. The temperature sensor should be positioned away from heat sources to ensure accurate readings.
