eTR 101 Modbus
Room Temperature Control Unit
Temperature controller
The Room Temperature Control Unit eTR 101 Modbus measures the room temperature and displays the current value. The target temperature can be changed using the + and - touch buttons. The eTR 101 Modbus is a Modbus server with RS485 interface and RTU protocol. Modbus client, e.g. PC, SPS or MC, can read the measured values and other settings with ""Function 04h (read input registers)"" or with ""Function 06H (write single register)"" and ""Function 10H (write multiple registers)"" adjust, for example, the display of the setpoint or the basic setpoint shifts.
Models:
N° 30184 eTR 101 Modbus, signal white RAL 9003 – Version with locking screw on the bottom of the housing
N° 30185 eTR 101 Modbus, jet black RAL 9005 – Version with locking screw on the bottom of the housing
N° 30180 eTR 101 Modbus, signal white RAL 9003 – Discontinued model, no longer produced
N° 30181 eTR 101 Modbus, jet black RAL 9005 – Discontinued model, no longer produced
Note on the changeover of the eTR series housing from January 2025:
The new models have a locking screw on the bottom of the housing. This makes it more difficult to remove the device from the wall. It can only be installed and uninstalled with a tool (screwdriver). The new design thus creates a barrier to unauthorised tampering. The installation depth of the new models is increased by approx. 0.5 mm. Appearance, range of functions and ETS application remain the same.
- Temperature measurements.
- Display of the current temperature or the setpoint and the basic setpoint shifts
- 2 touch keys (+/-) for changing the target temperature or the basic setpoint shifts
