UC150 is a communicative room heating controller with one PWM output for control of a radiator or electrical heater. It can work autonomously, or in connection to a primary controller (SoftPLC) or a building management system (RcWare Vision or any SCADA).

  • Systems with radiators or electric heaters – control and measuring of room temperature
  • monitoring and communication of room temperatures

The controller reads actual room temperature, setpoint shift by a knob, and set operation status which is set by short push of the knob. The room temperature is measured in the range of 0 to +60 °C. Measured and set values are processed in a PI algorithm, at the output of which there is a PWM controlled triac. All values are displayed on a large LCD display. 

The output works either as PWM controlled by a PI controller, or on/off (thermostat). The functionality and control parameters, i.e. P and I constants, and hysteresis for the on/off mode (in the P parameter field), can be set with domat.exe, the configuration software, which is free to download at www.rcware.eu.
