The Room Temperature Controller KNX eTR 101-BA2 measures the room temperature and displays the current value in white illuminated figures. Via the bus the device can receive an external measured value and process it with own data to overall temperature value (mixed value). The KNX eTR 101-BA2 has a integrated PI controller for a heating/cooling system. Either binary contacts such as pushbuttons or window contacts or analogue temperature sensors T-NTC can be connected to 2 inputs
Models:
N° EL-71313 KNX eTR 101-BA2, signal white RAL 9003 – Version with locking screw on the bottom of the housing
N° EL-71314 KNX eTR 101-BA2, jet black RAL 9005 – Version with locking screw on the bottom of the housing
Functions
- Measurement of temperature. Mixed value from own measured value and external values (proportions can be set in percentage), output of minimum and maximum values
- Display of the actual value or the target value/basic setpoint shift
- 2 touch buttons (+/-) for adjustment of the room temperature
- PI controller for heating (one or two step) and cooling (one or two step) depending on temperature. Control according to separate target values or basic target temperature
- 2 inputs for binary contacts or T-NTC temperature sensor
- Configuration is made using the KNX software ETS 5
