UB200 Communicative heating and cooling controller, BACnet MS/TP

Communicative heating and cooling controller, BACnet MS/TP

UB200 is a communicative room heating controller with two inputs and two onoff/
PWM outputs for control of a radiator or electrical heater and a cooling valve
(cooling panels, chilled ceilings). It can work autonomously, or in connection to a
primary controller or building management system over BACnet MS/TP.

Datasheet

UB200 is a communicative room heating controller with two inputs and two on-off/PWM outputs for control of a radiator or electrical heater and a cooling valve (cooling panels, chilled ceilings). It can work autonomously, or in connection to a primary controller or building management system over BACnet MS/TP.

  • Systems with radiators, electric heaters, or floor heating, and chilled ceilings or panels – 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 +50 °C. Measured and set values are processed in a PI algorithm, at the output of which there are two PWM controlled triacs. All values are displayed on a large LCD display. 

Controllers are intended for operating in a normal and chemically non-aggressive environment. They do not need any servicing or maintenance. The device consists of two parts: bottom with screw terminal block and cover containing PCB, display, and the knob. The bottom part is fixed by 2 or 4 screws to any flat surface or a flush-mounting box Ø 50 mm. At the back of the bottom there is an aperture for cabling. The bottom should be installed and cabling connected first, and the upper part inserted after the construction works are finished to prevent damage to the controller. 

The controller contains real time clock with a weekly scheduler (6 events per day). It changes between three operation modes: Day, Night, and Off. A short push in the Night mode switches to Party mode – Comfort extension by 2 hours.
