Description
Output set point for temperature
control.
If the object receives a base set
point which is lower than the
minimum valid base set point,
the base set point will be
increased to the value set here.
If the object receives a base set
point which is higher than the
maximum valid base set point,
the base set point will be set to
the value set here.
Limits the possible setting range
for the set point offset function.
Applies to both the
man. set point offset
as well as the rotary control17.
Example: for a base set point of
21°C in heating mode and a
reduction by 2K, the device
regulates with a set point of 21
– 2 = 19°C.
By what value should the
temperature be reduced in night
mode?
Preset temperature for frost
protection mode in heating mode
(Heat protection applies in
cooling mode).
Feedback of current set point
value via the bus:
The set point actually being used
for control is always to be sent
(= current set point).
Example with Base set point
21 °C and dead zone 2 K:
During heating, 21 °C is
transmitted and during cooling,
base set point + dead zone is
transmitted
(21 °C + 2 K = 23 °C)
