UB200
Summary
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.

Function
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 is a PWM controlled triac. All values are displayed on a large LCD
display.
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.
The digital inputs read signals from a window contact and presence sensors. They can be
used optionally.
The communication bus is RS485 with BACnet MS/TP protocol, therefore the controllers
are easily to integrate into most of the up-to-date SCADA or BMS system. See the BACnet
PICS in Annex 1 below.
