Programmable Functions; Setting The Current Time; Control Of Temperature 1 (Water Heating); Alarm Setting Temperature - Hobby Biotherm pro Mode D'emploi

3. Programmable functions

In program mode, the functions can be configured in the following sequence.

3.1 Setting the current time

The factory presets the time at 12:00:00. The time setting is not cleared during a reset however.

3.2 Control of temperature 1 (water heating)

The temperature is regulated with a precision of 0.2° C. The temperature can be set within the range 10.0-40.0° C.
The factory presets the relative humidity to 25° C. It is possible to program two turn-on/turn-off times to simulate the
drop in temperature at night. The Biotherm pro system has an automatic sorting function which will re-arrange the
time periods into the correct sequential order when exiting program mode.

3.3 Alarm setting temperature

An audible and visual alarm is triggered when the temperature exceeds or drops below the programmed desired
value. An alarm window between +/- 1° and 5° C can be set. The factory setting is the value 00 (no alarm).
Example: Temperature 25° C, alarm window +/- 3° C means that an alarm is triggered below 22° C and above 28° C.

3.4 Deactivation/Activation of audible temperature alarm

The audible alarm can be switched "ON" or "OFF". The factory setting is "OFF", as otherwise an alarm could be
triggered immediately when the system is first put into service whilst the sensor is located outside the aquarium,
where the temperature may be either too high or too low.

3.5 Choice of HEAT /COOL mode

A convenient inversion function makes it possible to switch from HEAT to COOL . This permits connection to an
external Cooling device instead of a Heater to counteract an increase in temperature.
3.6 Automatic control temperature 2 (floor heating/cooler)
Slot 2 (floor heating) is automatically regulated 0.1° C (preset) higher. The difference to the water temperature can be
programmed between 0.1 and 5.0° C.
Example: You have set the water temperature to 25.0° C. When 25.0° C is measured, slot 1 (water heating) is swit-
ched off. The floor heating remains active. If the floor heating system is so powerful that 25.1° C is measured, slot 2
(floor heating) is also switched off.
A warm substrate strengthens the roots of plants, encourages biological substrate activity and generates a circulati-
on in the substrate to improve the transport of oxygen and nutrients. This provides the best possible conditions for
healthy plant growth.
Hint: Submersion tube heaters with a thermostat should be set 3-4° C higher than the desired temperature to ensure
correct operation of electronic control via the Biotherm pro system.

3.7 Timer control

As an alternative to temperature regulation, the second slot ( ) can be used to control external devices via a timer
switch with a one-second control interval. It can be selected between ON, Aut, and Int. If ON Mode is selected the
external device at slot 2 is permanent activated. If Automatic Mode is selected up to 8 turn-on/turn-off times can be
programmed. The Biotherm pro system has an automatic sorting function which will re-arrange the time periods into
the correct sequential order when exiting program mode. If Interval mode is selected external devices are switched on
for at least 1 second and switched of for at least 30 minutes.
Attention: The Biotherm pro system can be optionally operated in the temperature 1 control (slot 1) + temperature 2
(slot 2) combination, or the temperature (slot 1) + timer switch (slot 2) combination. Programming a temperature for
slot 2 ( ) will delete the programmed settings for a timer switch on slot 2 ( ) and vice versa.
