When delivered the controller displays will be in German.
Other options can be selected in the „Language“ menu (refer to 4.3.2):
English, Francais
After mains failure, manual input is required to continue the
thermoregulation procedure.
Other options can be selected in the „Mains Failure Auto“ menu (refer
to 4.3.7): On (enabled). After mains failure or even after activation/
deactivation, the thermoregulation procedure will be continued
automatically. The setpoint programmed last will be used for
thermoregulation.
Three options are available. (The default setting is „Auto“)
1.„Auto“
2.„On“
3.„Off“
1.„Auto“ means that the compressors will only operate when cooling is
required.
2. Always Off means that the compressor will not turn on even if
cooling is required
3.Always On means continuous compressor operation even when
cooling is not required)
The thermal fluid temperature measured inside the thermostat is used
as the controlled variable for thermoregulation.
Other options can be selected in the „Control Mode“ menu (refer to
4.3.4):Process control
Process thermoregulation (cascade) is carried out via a process Pt100
sensor placed at a measuring point outside of the thermostat, e.g. in
reactor
The thermostat controls the temperature to the predefined setpoint of
20 °C. Use the SET key and the encoder to select other options (refer to
4.1 and 4.7): Any temperature value within the performance parameters
of the thermostat (refer to the Data Sheet 2.4 Appendix, type plate!) and
the safety limits (refer to 3.1!).
With this lower limit set at 5°C it is not possible to enter a lower setpoint.
The setting can be changed in the „Alarm Config.“ menu (refer to
4.4.1): Any temperature value within the performance parameters of the
thermostat (refer to the Data Sheet, Appendix or type plate.) and the
safety limits (refer to 3.1!).
With this upper limit set at 35°C it is not possible to enter a higher setpoint.
The setting can be changed in the „Alarm Config.“ menu (refer to
4.4.1): Any temperature value within the performance parameters of the
thermostat (refer to the Data Sheet, Appendix or type plate) and the fety
limits (refer to 3.1).
All the parameters changed by the customer can be reset to the default
values via the „Factory Default“ menu option.
The programs for operating the thermostat are described in Chapter 4 of
the Operating Instructions.
