7.7.2 Displaying the actual external temperature
With all Proline Thermostats an external temperature probe can be connected, which for example......
1. ... can be used as an independent temperature measurement channel.
2. ... can be used as the controlled variable for the bath temperature in applications with a no-
ticeable temperature gradient (between the internal bath temperature and an external load).
The setup is described in Section 7.7.4. With the function described in the following, you on-
ly change over the display!
External actual temperatures can also be read in by interface modules (
