Sensors - Domat Design line

The Domat Design line sensors solve the visual inconsistency and integration complexity that plague modern HVAC and BMS installations — providing unified wall-mounted sensing in multiple color options that blend seamlessly with interior design while offering flexible connection methods (passive Pt1000, 0-10V analog, Modbus RTU digital) to match any controller or retrofit scenario across offices, schools, and commercial buildings throughout the EU. Instead of mixing multiple sensor brands with varying sizes, color variations, and mounting methods that create visual clutter and commissioning confusion, this coordinated family delivers consistent 90×107×26mm housings in white, anthracite, light grey, and dark grey finishes while supporting both legacy wiring and modern digital protocols.

How unified design accelerates deployment: Every sensor in the Design line uses the same wall cutout and mounting approach, enabling standardized installation templates and reducing field mistakes. The UT001/UT051 passive Pt1000 sensors connect directly to existing controller inputs without additional electronics, eliminating drift and calibration issues while providing accurate temperature measurement for room compensation, outdoor reset, and zone control. UT090 CO₂+temperature transmitters deliver 0-10V analog outputs for direct PLC connection, enabling demand-controlled ventilation without digital protocol complexity. UT100/UT200 Modbus RTU sensors provide distributed digital temperature points with flexible probe options (external selection vs. included standard probe), supporting modern BMS architectures that prefer addressable field devices over analog wiring.

Technical capabilities include

• temperature ranges suitable for HVAC applications (-20 to +70°C for room/outdoor, -30 to +100°C for communicative variants),

• appropriate ingress protection (IP20 indoor, IP43 outdoor/harsh indoor, IP65 for technical areas),

• and proven sensor technologies—Pt1000 RTD for temperature, NDIR for CO₂ measurement with auto-calibration features.

• The analog transmitters include configurable scaling (0-5000ppm CO₂ range),

• while Modbus variants support standard function codes and register mapping for straightforward BMS integration.

All sensors maintain the unified design with four color options to match diverse interior specifications.

Installation considerations: Passive Pt1000 sensors require 2-wire or 3-wire configuration matching controller specifications; outdoor sensors need north-facing or shaded placement to avoid solar radiation; CO₂ transmitters require stable 24V power and proper grounding for clean analog signals; Modbus sensors need RS485 topology planning with appropriate termination and unique addressing.
