"Transmit individual state"
The 1 bit status object "Controller status, ..." contains the status information selected by the
"Single status" parameter. Meaning of the status signals:
"Comfort mode active" -> Active if operating mode "Comfort " or a comfort extension "" is
activated.
"Standby mode active" -> active if the "standby " operating mode is activated.
"Night-mode active" -> active if the "night " operating mode is activated.
"Frost/heat protection active" -> active if the "frost/heat protection" operating mode is
activated.
"Controller disabled" -> Active if controller disable is activated (dew point mode).
"Heating / cooling" -> Active if heating is activated and inactive if cooling is activated.
Inactive if controller is disabled.
"Controller inactive" -> Active with the "heating and cooling" operating mode when the
measured room temperature lies within the dead zone. This status information is always "0"
for the individual "Heating" or "Cooling" operating modes. Inactive if controller is disabled.
"Frost alarm" -> Is active if the detected room temperature reaches or falls below +5 °C.
This status signal will have no special influence on the control behaviour.
i
Upon a reset, the status objects will be updated after the initialisation phase. After this,
updating is performed cyclically every 30 seconds in parallel with the command value
calculation of the controller command values. Telegrams are only transmitted to the bus
when the status changes.
Command value limit
Optionally a command value limit can configured in the ETS. The command value limit allows
the restriction of calculated command values to the range limits "minimum" and "maximum". The
limits are permanently set in the ETS and, if command value limitation is active, can be neither
undershot or exceeded during device operation. It is possible, if available, to specify various
limiting values for the basic and additional stages and for heating and cooling.
i
It should be noted that the command value limit has no effect with "2-point feedback
control" and with "Transmitting of command values for heating and cooling via a common
object"! In that case it is still possible to configure the command value limit in the ETS, but it
will have no function.
The "Command value limit" parameter on the parameter page "Room temperature control ->
Controller general -> Command values and status output" defines the mode of action of the
limiting function. The command value limit can either be activated or deactivated using the 1-bit
communication object "Command value limit", or be permanently active. When controlling via
the object, it is possible to have the controller activate the command value limit automatically
after bus voltage return or an ETS programming operation. Here the "Command value limit after
reset" parameter defines the initialisation behaviour. In the "Deactivated" setting, the command
value limit is not automatically activated after a device reset. A "1" telegram must first be
received via the "Command value limit" object for the limit to be activated. In the "Activated"
setting, the controller activates the command value limit automatically after a device reset. To
deactivate the limit a "0" telegram must be received via the "Command value limit" object. The
limit can be switched on or off at any time using the object.
