What S+S Regeltechnik does
S+S Regeltechnik GmbH is a privately held German manufacturer of sensor and control technology for building and system automation, headquartered in Nuremberg and founded in 2001. The company designs and produces a broad portfolio of measurement devices covering temperature, humidity, pressure, air quality (CO2, VOC, fine dust, O2), brightness/presence, and flow, organized under sub-brands including RYMASKON (room operating units), PREMASGARD (pressure), KYMASGARD (wireless sensors), THERMASREG (thermostats), and RHEASREG (flow). Its core technology is built around industrial communication protocol support — Modbus, W-Modbus, BACnet, W-BACnet, and EtherCAT P — which positions the products for interoperability with major building management systems, and includes a room automation platform (RYMASKON) for controlling temperature, fans, sun protection, and lighting.
The business operates a vertically integrated model with its own 4,000 m² production facility in Nuremberg (plus a 2,600 m² second-phase expansion in preparation) and sells through three channels: a direct e-commerce storefront (spluss.com) with 24-hour delivery across Germany, a global distributor/dealer network, and trade fair-driven enterprise engagement. Revenue is generated almost entirely through one-time hardware sales, with visible catalog prices ranging from roughly $33 for basic frost protection thermostats to over $400 for advanced room controllers. Target end markets are diversified across use cases including Smart Buildings (primary), Smart Industry, Smart Agriculture, Smart Infrastructure, Smart Logistics, and Smart Cities, with no publicly disclosed large anchor customers. The company carries a "Made in Germany" quality positioning and a 5-year product guarantee, and has executed at least one acquisition (Consens, February 2022) to broaden its portfolio.

S+S Regeltechnik product offering
Product offeringCore offering
S+S Regeltechnik designs, manufactures, and sells intelligent sensor devices and room automation controllers for measuring and controlling environmental parameters including temperature, humidity, pressure, air quality (CO2, VOC, fine dust), brightness/movement, and flow. The portfolio is sold under brand families RYMASKON (room operating units), PREMASGARD (pressure), KYMASGARD (wireless), THERMASREG (thermostats), and RHEASREG (flow), supporting protocols such as Modbus, W-Modbus, BACnet, W-BACnet, and EtherCAT P for building and industrial automation customers.
Product overview
S+S Regeltechnik offers a comprehensive portfolio of measurement and control technology for building and system automation. The core product line centers on the RYMASKON® room operating unit series (RYM 1301, 1401, 1321C, 1361C, 1431C, 1461C, and RYMASKON 200 series) for intelligent room control managing temperature, humidity, fans, sun protection and lighting. Supporting the room automation system are sensor product categories including temperature sensors (passive and active with 0-10V/4-20mA output), humidity sensors and hygrostats, pressure transmitters (PREMASGARD® SHD and 11D series), air quality sensors (CO2, VOC, fine dust, O2), brightness/presence sensors, and flow monitors (RHEASREG® KLSW). Connectivity options include Modbus-SD, W-Modbus (wireless), BACnet, W-BACnet, and EtherCAT P protocols. The product range is complemented by PowerIO for flexible installation systems and comprehensive accessories for mounting, protection, and wiring. The company also offers customized product designs beyond the standard catalog range.
