H/c changeover
When value "Heating off/cooling on" is exceeded, the H/C changeover signal is
changed to cooling. When value "Heating on/cooling off" is exceeded, the H/C
changeover signal is changed to heating. Attenuation can be set for the input
signal.

If a digital input is used for changeover, operating line "Heating on/cooling off" = 1
and "Heating off/cooling on" = 0 must be set (factory setting).
If changeover by calendar and by digital input is configured at the same time, the
controller uses the latter.
