Setting a Temperature
1. Press the Set button and hold for 3 seconds. The Set indicator light
on the screen will appear.
2. Press Set button again. The temperature displayed on the screen
now is the target temperature.
3. While holding in the Set button, use the Up or Down buttons to enter
a desired target temperature.
4. Once you reach your desired target temperature, press the Power button
to set that temperature. You will then return back to the main screen.
The temperature displayed on the screen under normal working
status shows the current temperature.

Heating
The heat socket on the controller is for plugging a heating device
into. Most common is the Mangrove Jack’s Heat Belt or Heat Pad.
Cooling
The cooling socket on the controller is for plugging a fridge or
chiller into.
Temperature Probe
Insert the temperature probe into a fridge or temperature controller
box. If using a fridge it is best to read the temperature from the
middle of the fridge to get the most accurate reading of the
temperature inside.

Additional Settings
Apart from setting a target temperature (code F1), we recommend
keeping all other settings as their defaults. However, for your reference,
a complete list of the settings that you can change are described in the
table below:
To change settings other than setting a target temperature (F1):
1. Press the set button and hold for 3 seconds. The Set indicator light
on the screen will appear. The screen should also display “F1.”
2. Use the Up or Down buttons to select the code corresponding to the
setting of the function you would like to change.
3. While holding in the Set button, use the Up or Down buttons to enter
the desired value for that function.
4. Once you reach your desired target value, press the Power button to
set that value.
Code Function Default
F1 Setting a target temperature 10ºC
F2 Temperature hysteresis value 0.5ºC
F3 Cooling delay time (for compressor delay protection) 3 minutes
F4 Temperature calibration 0ºC

How do I change the temperature hysteresis value?
1. Press the set button and hold for 3 seconds. The Set indicator light on the
screen will appear.
2. Use the Up or Down buttons to select F2, the code corresponding to
temperature hysteresis value.
3. While holding in the Set button, use the Up or Down buttons to enter the
desired value.
4. Once you reach your desired target value, press the Power button to set
that value.
The cooling does not switch on immediately when the measured temperature
increases above the target temperature + hysteresis value. Is this normal?
The controller has been set to a default cooling delay time of 3 minutes. During
this delay time the Cool indicator light should be flashing. If the delay time you
experience is greater than 3 minutes, then this setting has likely been changed
from its default. To change the cooling delay time back to 3 minutes:
1. Press the set button and hold for 3 seconds. The Set indicator light on the
screen will appear.
2. Use the Up or Down buttons to select F3, the code corresponding to cooling
delay time.
3. While holding in the Set button, use the Up or Down buttons to select 3.
4. Press the Power button to set that value.
My controller does not display the correct temperature. How do I fix this?
The most likely cause for this is that the temperature calibration setting has
been changed from its default value of 0 ºC. To change this back:
1. Press the set button and hold for 3 seconds. The Set indicator light on the
screen will appear.
2. Use the Up or Down buttons to select F4, the code corresponding to
temperature calibration.
3. While holding in the Set button, use the Up or Down buttons to select 0.0.
4. Press the Power button to set that value.
