After selecting
confirm your menu settings by pushing
SET
You will then automatically return to the menu selection or to the control mode.
Note: in cooling operations (menu
“rd”=1), AH1(2) is the turn-on value and AL1(2) is the turn-off value after turning on!
IMPORTANT
The color coding of the sensors is not standardized. Polarity with clamps 6, 7, 8 causes a
fault message or an unrealistic display value. This will not damage the controller. If the
sensors are exchanged, the correctly installed sensor can be calibrated during operation at
a random reference temperature (see page 5, menu
PSb).
Make sure the sensor is suitable for the temperature range to be measured. PT 100
sensors with lower or higher measuring ranges can be connected to the device.
Push the "SET" button followed by code entry 0001 in order to gain access to these
parameters.
Use the below table for the setting of temperature values after you have entered the basic
settings according to the parameter table „Basic Settings“, page 13 correctly.
