Etymology or name origin
The name “Salus” is derived from Latin, meaning “health,” “well-being,” or “safety,” expressing the brand’s focus on reliability and user welfare. The model prefix “iT” represents “intelligent thermostat,” while the number “600” indicates its succession within the manufacturer’s product lineage, denoting enhanced feature sets and wireless expansion. This taxonomy has shaped brand perception within the UK and European heating controls market, conveying technological progress, modular flexibility, and installer trust.
Overview / context
Industry background
Heating controls have transitioned from mechanical dials to sophisticated wireless platforms in response to shifts in energy prices, regulatory mandates, and occupant expectations. The drive toward “smart” infrastructure reflects both consumer desire for convenience and legislative pressure for efficiency. Within this context, the Salus iT600 system emerges as a defining technology, aligning its architecture with boiler upgrades, underfloor heating deployments, and energy efficiency retrofits.
Control system architectures
Core heating systems commonly utilise a combination of boilers, radiators, and underfloor circuits, historically managed by a central, wall-mounted thermostat or timer. In contrast, the iT600 introduces a distributed architecture through wireless linkages and app integration, supporting per-zone programming, occupancy-based scheduling, and adaptive modulation for diverse heating plant configurations.
Smart versus traditional controls
Traditional controls regulate temperature by toggling the entire heating system according to coarse time and temperature presets, often wasting energy in unused areas. The iT600 replaces this with precise, room-level data collection and actuation, enabling your organisation to dynamically adjust temperature programming and achieve measurable reductions in energy use. Mobile app access and programmable routines introduce a level of flexibility and adaptability unavailable in legacy systems.
Interoperability with plumbing and HVAC infrastructure
The iT600’s open protocol compatibility, especially with OpenTherm-enabled boilers, makes it suitable for a range of heating plant types, from combi to system and regular boilers. Its actuators and controllers interface seamlessly with both radiators and manifold-fed underfloor heating. Property upgrades can thus leverage existing pipework and emitters while gaining the efficiencies and reporting of a modern control scheme. Maintenance, troubleshooting, and extension of the system are further supported by installer networks such as Plumbers 4U, ensuring ongoing adaptability to your changing property requirements.
