Setting the temperature control mode
When using an external PT 1000 temperature sensor, the user can
choose between two types of control:
PI mode
Good control results, minimized overshooting, slow rise in temperature
2P-mode (two-point controller)
Maximum heating rate, increased overshooting
Factory setting: PI mode
Changing the temperature control mode
1. Set target temperature to 2 °C
2. Switch off device
3. Hold down temp knob
4. Switch on device
This activates or deactivates the two-point controller (2P) for the
external PT 1000 temperature sensor (2P appears on the display).
When switching on the device, 2P is also displayed next to the
operating mode A/B/D when the two-point controller is activated.
When the heating function is active in 2P mode, (with external PT 1000
temperature sensor) the actual temperature flashes - that notifies the
user that the process temperature has been greatly overshot!
