Description
Specifies the buffer zone
between set points for heating
and cooling mode.
The dead zone is expanded
through hysteresis in switching
(2 point) control.
See in the Appendix: Dead zone
The standby temperature is
increased in cooling mode.
The in cooling mode, the
temperature is increased in night
mode.
Heat protection represents the
maximum permitted temperature
for the controlled room. It
performs the same function
during cooling as the frost
protection mode during heating,
e.g. saves energy while
prohibiting non-permitted
temperatures.
