+ hysteresis cooling
22
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
Increase in standby mode
(during cooling)
0 K, 0.5 K, 1 K
1.5 K, 2 K, 2.5 K
3 K, 3.5 K, 4 K
4.5 K, 5 K
The standby temperature is
increased in cooling mode.
Increase in night mode
(during cooling)
3 K, 4 K, 5 K
6 K, 7 K, 8 K
The in cooling mode, the
temperature is increased in night
mode.
set point for heat protection
mode
(during cooling)
0 = 42 °C, i.e. no real
heat protection
29 °C, 30 °C, 31 °C
32 °C, 33 °C, 34 °C
35°C
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.
