1.
Setting the target temperature
When the display is flashing and no symbols are shown on the left hand side choose
the target temperature for the aquarium. This can be done by pressing the up and
down keys until the desired temperature is displayed. Once done confirm by pressing
the ‘SET’ button.
2.
Setting the cooling differential
The snowflake symbol should be flashing on the top left of the screen to indicate that
the cooling differential can be set between 0.3 and 2.0ºC. Using the up and down
arrows select how far above the set temperature you want the aquarium to reach
before the cooling socket is activated. Press the ‘
SET
’ button to confirm.
3.
Setting the heating differential
The sun symbol will flash on the middle left of the screen to indicate that the
heating differential can be set between 0.3 and 2.0ºC. Using the up and down arrows
select how far below the set temperature you want the aquarium to be before the
heating socket is activated. Press the ‘
SET
’ button to confirm.
4.
Setting the alarm function
The alarm symbol will flash on the bottom left of the screen. Using the up and down
arrows set how far from the target temperature the aquarium can be before the
unit will alarm. This should be set to a larger number than your heating and cooling
differential settings. Press the ‘
SET
’ button to confirm and exit the settings. The display
should stop flashing and will be showing the current tank temperature.
Example setup
- The target temperature is 25.0°C +/- 0.3°C, with an alarm set for 25°C
+/- 0.7°C.
•
The target temperature is set to 25.0°C
•
The cooling differential is set to 0.3°C
•
The heating differential is set to 0.3°C
•
The alarm differential is set to 0.7°C
When the temperature in the aquarium rises above 25.3°C, the cooling power socket
will be energized and the attached fan/chiller will switch on (after 3 minute short
cycle delay). The cooling power socket will remain on until the aquarium temperature
reaches 25.0°C.
When the temperature in the aquarium falls below 24.7°C, the heating power socket
will be energized and the attached heater will switch on. The heating power socket will
remain energised until the aquarium temperature reaches 25.0°C.
If the aquarium temperature falls below 24.3°C or rises above 25.7°C, the alarm will
activate displaying the flashing alarm icon and sounding an audible alarm.
