How to proceed:
•
When the unit has been operating for about
one day, check the water temperature with a
precision 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 obstructed 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 control-
ler. 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 calibra-
tion range.
