When using an external PT1000 temperature sensor, the user can
choose between two types of control:

PI mode
Good control results, minimised overshooting, slow rise in tempe-
rature.

2P mod (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 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!
