Checking the temperature values
N O T E
The heater switches on and off automatically in order
to maintain the set temperature.
A light in the glass bulb indicates that the heater is
functioning.
The light and heater are switched off when the set
temperature is reached.
How to proceed:
• When the unit has been operating for about one
day, check the water temperature with a preci-
sion thermometer.
• The measured temperature is lower than the set
temperature: Check the water flow around the
unit and, if necessary, move the unit to a different
position where the water circulation is not ob-
structed by e.g. plants
• Measure the temperature again after some time.
• The temperature difference is still too great:
Calibrate the unit. (-> Calibrating the unit)
• The measured temperature is higher than the set
temperature: Calibrate the unit. (-> Calibrating
the unit)
Calibrating the unit
• Calibration range: It is possible to calibrate the
unit by plus 3°C and minus 3 °C.
• The calibration controller protrudes out of the
different-coloured temperature controller. There
are 3 fixed positions in the plus and minus range.
Each position corresponds to approx. 1 degree
centigrade.
N O T E
Do not attempt to go outside the calibration range.
How to proceed:
 E
• Use a screwdriver for the calibration or break the
supplied tool out of the holder.
• Measured temperature is too high: Keep the
temperature controller at the set value and move
the calibration controller in the direction of - (mi-
nus).
• Measured temperature is too low: Keep the
temperature controller at the set value and move
the calibration controller in the direction of +
(plus).
