ELSNER 70651 KNX eTR 101 Room temperature controller, black

The KNX eTR 101 room temperature controller, model 70651, is a device designed to measure and regulate indoor temperature with precision and efficiency.

Key Features

This controller measures the ambient temperature and displays the current value in digits illuminated in white. Through the KNX bus, the device can receive external temperature values and combine them with its own data to obtain an overall temperature value (mixed value), with proportions that can be set as a percentage.

Control functions

• Temperature measurement with the possibility of calculating a mixed value from values measured internally and externally.
• View the current value or setpoint/base value.
• Ambient temperature adjustment using two touch buttons (+/-).
• Temperature control through an integrated PI controller for heating and cooling systems (one or two stages).
• Control based on separate setpoint values or base setpoint temperature.

Configuration and Installation

<p-The configuration of the device is carried out using the KNX ETS 5 software. The controller features a compact design with dimensions of 81.5 mm x 81.5 mm and a mounting depth of approximately 12 mm. The case is made of glass and plastic, available in white (RAL 9003) and black (RAL 9005).
