UI0xx
Communicative room units and
sensors
Summary
The UI... room unit range is a family of universal communicative human-machine
interface for control of HVAC units and plants, and IRC controllers. The units
communicate over Modbus RTU / RS485 and they can be used as open system
components with majority of building control system and controllers.
Application
▪ripening and cooling boxes, datacenters, controlled climate storage rooms,
alarm messaging systems etc.
▪systems with fancoils, convectors, floor and radiator heating, AHUs, air
conditioning units.
▪control of boilers, DHW, heating circuits, building controls in general
▪monitoring of room temperature and humidity
▪with a SCADA system: temperature, humidity and status recording, remote
control.
Function
The units acquire temperature and optionally relative humidity in room, temperature
correction (knob) and required operation status which is set by push of the button or
in menu. In the configurable menu following values can be set and displayed:
-temperature, actual temperature correction
-humidity (actual value only at room units containing the humidity sensor)
-time (only display at room units with RTC)
-basic setpoint - day
-basic setpoint - night
-outside temperature for heating enable
-DHW temperature
-heating curve type (1...4)
-operation mode (Residential with Day, Night, Time schedule, Off, or Hotel /
Office with Comfort, Standby, Party, Off)
-fan stage (Auto, Off, St.1, St. 2, St. 3)
-A/C mode (Auto, Heating, Cooling, Off, Fan only)
-weekly scheduler: 7 days, up to 6 events per day

-another 5 variables (air quality, fan speed etc.) –each has a profile where max.
and min. values, step, number of decimals, and symbol set are defined.
It is also possible to set / reset any of the LCD symbols on the display over Modbus.
The turn / push knob has three basic functions:
•instant edit (turning the knob) –settings of one predefined analogue value,
usually room temperature correction
•quick edit (short push) –change of predefined state, e.g. Presence (Comfort /
Standby / Off), Air condition (Auto / Heating / Cooling / Fan only / Off) etc.
•long push –jump to menu where values are listed by turning the knob, short
push selects the value to be edited, and the value is changed by turning the
knob followed by short push for confirmation.
After definable inactivity time, the display goes back to its basic state with rolling
display of selected values (e.g. actual temperature and humidity).
The unit Modbus address and functionality is defined over the RS485 interface with
service software ModComTool which is free for download at http://domat-
int.com/en/downloads/software To interface the room unit to the computer use the
USB/485 converter M080, RS232/RS485 converter M012, or any suitable RS485
converter.

Units with no knobs are used as indicators, units with no knobs / display are used as
communicative temperature / rH sensors, both optionally with remote controlled
inputs / outputs. Process control algorithms (activating of the outputs by increased /
decreased temperature, humidity etc.) must be implemented in a master controller.

Dimensions
All dimensions in mm.
Installation
Units are intended for operating in a normal and chemically non-aggressive
environment. They do not need any servicing or maintenance. Install them in a vertical
position at places where they can be operated easily and measure correct values of
temperature and humidity, i.e. in the height of about 150 cm, with no direct sunlight
or other heat / cool source (AHU outlets, refridgerator, electrical appliances). 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 have been finished to prevent damage to the unit.
Seal the conduits to avoid influencing the sensor by draught. Use insulating pad when
installing the sensor on cold walls. Avoid sensor exposition to sunlight or other heat
sources.
Opening the
cover
When removing the display part, proceed as follows:
-press gently the side parts of the unit and pull the right of the display part by
several milimeters
-pull the left of the display part
6 03/2017 Subject to technical changes. domat UI0xx
-pull the display part and remove it from the bottom.
Do not bend the display part too much, the connector pins could be damaged. The
locks are only at the sides of the display part, not at the top nor bottom.
Display
Over Modbus, it is possible to set /
reset the complete symbol set except
for the 7 segment digits, „Error“ and
„Setting“ texts, and symbols of °C, °F,
%, and rH. Those are part of the
configurable menu profiles. The
register description is available in a
separate document Room units UI... –
Communication description.
LCD symbol set (see in the picture).
RoHS notice
The device contains a non-rechargeable battery which backups the real-time clock and
part of the memory. After the device is not operable, please return it to the
manufacturer or dispose of it in compliance with local regulations.
