Peripherals

The Domat peripheral field device portfolio eliminates the complexity and compatibility risks of multi-vendor sensor procurement by providing a complete, systematized range of HVAC and BMS sensing solutions.

How comprehensive coverage streamlines integration: Every device category supports multiple sensing technologies (passive Pt100/Pt1000/Ni1000/NTC, active 0-10V/4-20mA outputs, Modbus RTU digital communication) and installation methods (wall-mount, duct-mount, immersion, strap-on, pendulum) to match any retrofit or new construction scenario. The systematic approach spans essential HVAC measurements—temperature (room/duct/outdoor/mean-value), humidity and IAQ, CO₂ for demand-controlled ventilation, static and differential pressure, airflow monitoring, frost protection, and occupancy detection — with consistent documentation, mounting accessories, and technical support across the entire range.

Key product families address specific integration challenges:

Presence & Lighting (DIP200) combines PIR occupancy and illuminance sensing in a single ceiling device with swappable lens optics and Modbus communication for daylight harvesting and HVAC setback strategies.

Temperature Sensing ranges from basic passive room sensors (RTF1) through high-precision immersion probes (TF65 IP67) to communicative Modbus variants (HFTM-Modbus) with cable or stem configurations.

Humidity & IAQ includes duct-mount (KFTF series) and wall-mount (AFTF series) transmitters with combined temperature outputs, while CO₂ sensors (RCO2-W, RFTM-CO2-W) support both standard (0-2000ppm) and high-occupancy (0-5000ppm) ranges for demand-controlled ventilation.

Pressure & Flow measurement covers static pressure transmitters (SHD series, 0-1 to 40 bar), differential pressure for filter monitoring and airflow verification (Premasgard series, ±25Pa to ±10 bar), and flow switches for pump protection.

Thermostats & Protection provide frost protection (FST series with sensing lengths up to 6m), mechanical room thermostats (RTR series), and strap-on/immersion variants for local safety cutoffs.

Wireless Solutions (W-ALTM1, W-AFTF, W-GATEWAY) enable sensor deployment in locations where wiring is impractical, with wModbus gateways providing standard Modbus RTU integration.

Room Units & HMI (RTF series) combine sensing with local user interfaces — pushbuttons, LEDs, setpoint adjustment, mode selectors—supporting various sensing elements (Pt100/Pt1000/Ni1000/NTC) to match controller input requirements.

Mounting Accessories include immersion sleeves (TH08 brass/stainless), duct flanges (MF-15-K), and installation hardware ensuring proper sensor placement and environmental protection.

Technical advantages include wide operating ranges (-50°C to +180°C depending on application), appropriate ingress protection (IP20 to IP67), galvanic isolation on digital variants, and proven sensor technologies with documented accuracy specifications. Selection flexibility supports legacy installations (passive resistance sensors) through modern digital architectures (Modbus RTU) while maintaining consistent mechanical interfaces and installation procedures.

Constraints: Match sensor constant (Pt/Ni/NTC) to controller input specifications; segregate low-voltage signal cables from mains wiring; respect immersion pocket lengths and duct insertion depths; follow RS485 topology rules for Modbus devices; plan wireless gateway placement for reliable coverage; observe environmental limits for humidity and CO₂ sensors.
