Lighting time (in minutes) 1…60; 10 4.4. Temperature controller The KNX K8 actuator provides eight temperature controls that are independent of the device outputs and thus may also be used for the control of other heating/cooling actuators. 4.4.1. General regulation For an adequate regulation of the indoor temperature, comfort, standby, eco and building protection modes may be used. - Page 15 The status object shows the current status of the output variable (0 = OFF, >0 = ON) and may, for example, be used for visualisations or to switch off the heating pump as soon as the heating is off.
