access to the changeover switch by pulling out the quick
reference and removing the plastic disk in front of it.

Testing inputs and outputs
To test inputs and outputs, you need to read off and set parameters
using the operator panel. Skip any tests which are not relevant to your
installation.
Procedure for testing inputs and outputs:
1. Check that all the temperatures are reasonable. Follow the
instructions in chapter 4.
2. Ensure that the controller is in the “timed operation” operating
mode. There is a description of how to set the operating mode in
chapter 4.
3 Close input X2 (extended daytime operation) to measurement
neutral (M) and check that the clock and the flashing sun appear
in the display window.
