4.2.4.4 Controller extension
The device unites two independent room temperature controllers (Controller 1 and Controller 2).
Each controller is an independent function section of the device and has its own parameter and
object range in the ETS. Therefore, the room temperature controllers can be switched on or off,
irrespective of the pushbutton sensor function, or configured as a controller extension.
A controller can be used for single-room temperature control. Depending on the operating
mode, current temperature setpoint and room temperature, command values for heating or
cooling control and fan controller can be sent to the KNX. These command values are usually
then converted by a suitable KNX actuator, e.g. heating or switching actuators or directly by
bus-compatible actuating drives, evaluated and converted to physical variables for air
conditioning control.
The controllers of the device can either work as a main controller or as a controller extension.
As the main controller, the room temperature controller function is fully switched on and the
control algorithm activated. Only the main controller transmits control value telegrams. A
controller extension itself is not involved in the temperature regulating process. With it, the user
can operate the single-room controller, i.e. the main controller from different places in the room.
In this way, any number of operating extensions can be set up.
In this chapter, the functions of the room temperature controller are described as an extension.
i
The following chapters on room temperature control apply for both Controller 1 and
Controller 2. The functions of both controllers are identical.
4.2.4.4.1 Connection to room temperature controller
Function
The controller extension can be activated to control a KNX room temperature controller. The
controller extension function is enabled using the "Controller extension
n
" setting of the
parameter "Controller
n
" in the "Room temperature control" parameter node.
The controller extension itself is not involved in the regulating process. With it, the user can
operate the single-room regulation from different places in the room. It can also be used to
adjust central heating control units which are located, for instance, in a distribution box.
Typical KNX room temperature controllers generally offer different ways of influencing or
visualising the room temperature control...
-
Switching over between different modes of operation (e.g. "Comfort", "Night" ...) with
different setpoint temperatures assigned to each mode by the thermostat.
-
Signalling the presence of a person in a room. The signalling may also be combined with a
configured switchover in the mode of operation.
-
Readjustment of the setpoint temperature in levels which are referred in each case to the
configured setpoint temperature of the current operating mode (basic setpoint shift).
The room controller display compact module permits by means of its control buttons the
complete control of an external room temperature controller by changing the operating mode, by
predefining the presence situation or by readjusting the setpoint shift (cf. the following sub-
chapters). For this purpose, the TSM buttons selected as extension operation buttons must be
configured for the "Controller extension" function.(see chapter 4.2.4.6.7. Controller extension
function). It should be noted that an extension operation is possible only with button
