Art. No. SC 1000 KNX
"Heating" or "cooling" single operating modes:
In heating mode, the controller will turn on the heating when the room temperature has fallen
below a preset limit. In heating mode, the feedback control will only turn off the heating once a
preset temperature limit has been exceeded.
In cooling mode, the controller will turn on the cooling system when the room temperature has
exceeded a preset limit. The control system will only turn off the cooling system once the
temperature has fallen below a preset limit. In this connection, variable "1" or "0" will be output,
depending on the switching status, if the temperature exceeds or falls below the hysteresis
limits.
The hysteresis limits of both operating modes can be configured in the ETS.
i
It has to be pointed out that the message objects for heating and cooling will already
become active as soon as the temperature falls short of the temperature setpoint of the
active operating mode in case of heating or exceeds the temperature setpoint in case of
cooling. In this case the hysteresis is not being considered.
The following two images each show a 2-point feedback control for the individual operating
modes "Heating" (figure 89) or "Cooling" (figure 90). The images take two temperature
setpoints, one-stage heating or cooling and non-inverted command value output.
