Building Technologies Central apartment unit QAX910 23.08.2008
To change over between the plant operating modes heating and
cooling, the preset H/C changeover locking time must be expired.
This avoids frequent changeover.
The central apartment unit checks the mixed outside air temperature as a
second criterion and compares it to the outside temperature heating limit and
the outside temperature cooling limit (see page 31).
