Parameters for heating / cooling operation
Dead zone between heating
and cooling
1 K, 1,5 K, 2 K,
2,5 K, 3 K, 3,5 K
4 K, 4,5 K, 5,5 K
6 K
Specifies the interval between
set point value in heating and
cooling operations.
Example with set point value
of 21°C and Dead zone of 2K:
Cheops will only start cooling
when the temperature ≥ Set
point value + Dead zone is,
i.e. 21°C + 2K = 23°C.
Increase in standby mode at
cooling
0,5 K, 1 K, 1,5 K
2 K, 2.5 K, 3 K
3,5 K, 4 K
The temperature is increased
in standby mode during
cooling operation
Increase in night mode at
cooling
3 K, 4 K, 5 K
6 K, 7 K, 8 K
See increase in standby mode
Set point value for heat
protection at cooling
42 °C (no heat protection)
29 °C, 30 °C, 31 °C
32 °C, 33 °C, 34 °C
35 °C
The heat protection represents
the maximum permitted
temperature for the controlled
room. It performs the same
function on cooling as frost
protection mode on heating,
e.g. saves energy while
prohibiting non-permitted
temperatures
Important:
In principle, Cheops control
will not allow a set point
value above 42
o
C (even via
bus set point value
definition)
