| NRT 107: Room- and flow-temperatur controller
How energy efficiency is improved
Analogue input for shifting setpoint depending on outside temperature and integrated time-switch for individual programming of changeover between normal operating mode and operation at reduced temperature.
Areas of application
Room temperature compensated control (heating, cooling, heating/cooling) of individual rooms in 2- or 4-pipe systems with activation of drives, pumps and fans.
Properties
- Detection of room temperature with choice of integrated or external temperature detector
- High level of operating convenience thanks to buttons on front and large LCD display
- Intuitive user interface
- Modern design
- Weekly and annual switching program with 3 temperature levels
- Automatic changeover between summertime and wintertime
- Selection of 8 basic controller models for different applications
