Room temperature controller | Room temperature controller - General
Command values for heating and cooling to separate objects (4-pipe / 2 circuits)
If the parameter is set to "Yes", the command value will be transmitted to a shared
object during heating or cooling. This function is used, if the same heating system is
used to cool the room in the summer and used to heat the room in the winter.
This parameter is only visible with "Heating and cooling" mixed operating mode.
Additional separate command value ob-
jects
If the parameter is set to "yes", two separate objects "Command value heating" and
"Command value cooling" are displayed in addition to the shared object "Command
value heating/cooling". These objects are for both visualisation purposes and also
rooms with, for example, combined wall heating/cooling and separate underfloor
heating.
This parameter is only visible in the mixed "Heating and cooling" operating mode
with output of the command values to a shared object.
Type of heating control (if applicable, for
basic and additional level)
Selecting a feedback control algorithm (PI or 2-point) with data format (1-byte or 1-
bit) for the heating system.
Type of heating (if applicable, for basic
and additional level)
Adapting the PI algorithm to different heating systems using predefined values for
the proportional range and reset time control parameters.
With the "Using control parameters" setting, it is possible to set the control paramet-
ers in a manner deviating from the predefined values within specific limits.
This parameter is only visible if "Type of heating control = Continuous PI control".
Proportional range
Separate setting of the "Proportional range" control parameter.
This parameter is only visible if "Type of heating = via control parameter" and the
heating control type "PI control".
Reset time (0 = inactive)
Separate setting of the "Reset time" control parameter.
This parameter is only visible if "Type of heating = via control parameter" and the
heating control type "PI control".
