Basic and additional
heating and cooling
The room temperature controller
distinguishes between two different
operating modes. The operating modes
specify whether you want the controller
to use its variable to trigger heating
systems ("heating" single operating
mode) or cooling systems ("cooling"
single operating mode). You can also
activate mixed operation, with the
controller being capable of changing
over between "Heating" and "Cooling"
either automatically or, alternatively,
controlled by a communication object.
In addition, you can establish two-level
control operation to control an additional
heating or cooling unit. For two-level
feedback control, separate command
values will be calculated as a function of
the temperature deviation between the
setpoint and the actual value and
transmitted to the bus for the basic and
additional levels.
This parameter specifies the operating
mode and, if necessary, enables the
additional level(s).
Additional stage inhibit
object
Yes
No
The additional stages can be separately
disabled via the bus. The parameter
enables the disable object as necessary.
This parameter is only visible in two-
level heating and cooling operation.
Transmit heating and
cooling command
values to one common
object
Yes
No
If the parameter is set to "Yes", the
command value will be transmitted on 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, if applicable, with additional
levels.
Type of heating control
(if applicable, for basic
and additional stage)
Continuous PI control
Switching PI control (PWM)
Switching 2-point feedback
control (ON/OFF)
Selecting a feedback control algorithm
(PI or 2-point) with data format (1 byte or
1 bit) for the heating system.
