Cause

The CZU controller is not controlling.

Resolution

A DRT3451, STR611 or a STR612 is used as both temperature sensor and setpoint adjust.

Check that the internal setpoint adjust within the controller is set 10'C.

If not, set it to 10'C, then the internal setpoint is ignored and the remote setpoint is used.
