Designation
Values
Meaning
Current set point value in
comfort mode
Transmit mean value between
heating and cooling
Transmit actual
temperature setpoint
(Heating < > Cooling)
Feedback of current set point
value via the bus:
Same value in comfort
operation mode during both
heating and cooling operation,
i.e.:
Basic set point value + half
dead zone
sent, to prevent room users
becoming irritated.
Example with basic set point
value of 21°C and dead zone
of 2K:
Mean value= 21°+1K =22°C
Although control takes place
at 21
o
C
and/or 23°C
The set point value actually
being controlled is always
sent.
Example with basic set point
value of 21°C and dead zone
of 2K:
During heating and cooling,
21°C and basic set point value
+ dead zone are sent
respectively (21°C + 2K =
23°C)
Parameters for 2-step heating
Differential between main
step and additional step
1 K, 1,5 K, 2 K,
2.5 K, 3 K, 3.5 K,
4 K
Specifies the negative interval
between the current set point
value and the set point value
of the additional step.
Example with basic set point
value of 21°C and 1K
differential:
Main step controls using the
basic set point value and the
additional step controls using
the basic set point value – 1K
= 20°C
