Wireless dry-contact signal transmitter (WiFi + RF)

TB01/TB08 · ThermoB Link series

230VHVAC Controllers & OEM SolutionsWiFiwireless

For a boiler, pump or alarm start signal without a cable. Wireless transmission of a relay signal (RF + WiFi); the hub serves up to 8 transmitters/outputs.

Why it matters

  • A wireless (RF + WiFi) system for relaying a single dry-contact relay state from one point to one or more other points
  • Transmitter TB01.TX.1 monitors an open/closed circuit on input SW1 and forwards the state wirelessly
  • Hub receiver TBH08-RO.1 (HUB-RF8.1) serves up to 8 modules (transmitters and/or remote outputs) and drives its own relay output R1

No cable between the wiring center and the boilerThe underfloor manifold and its wiring center are on one floor, while the boiler is in the basement — there is no control cable between them. Running one through finished floors is practically impossible.A separate temperature in every room — multi-zone underfloor heatingThe bedrooms overheat while the living room stays cold — the entire underfloor system is driven by a single thermostat and one temperature for the whole floor.Two independent zones with a shared heat sourceTwo zones — say a living floor and a bedroom floor, or two apartments sharing one boiler — must be heated independently, yet there is only one heat source.Fan coil with no cable to the boiler / heat pump – wireless demand with TB01The fan coil is in a room with no control cable run from the boiler, heat pump or wiring centre, yet the source must only start when the fan coil needs heating or cooling.Heat pump with underfloor heating and coolingThe heat pump supplies low-temperature water and the system responds slowly. Without zoning some rooms overheat while others never reach comfort, and when switching to cooling the logic of all zones must flip at once.Radiators upstairs, underfloor downstairs — one systemThe ground floor has underfloor heating with a manifold, the upper floor has radiators. The two systems need different control logic, yet a single boiler must start on demand from either of them.Renovation without opening walls: fully wireless controlThe walls are finished and the furniture is in place, but there is no heating control. Running new cables would ruin the renovation.Holiday house: warm on arrival, protected all winterThe house sits empty for months. The heating must not run for nothing, the pipes must not freeze, and on Friday evening the house should be warm before you even arrive.Large house with 8 wired zonesA new house with eight or more underfloor-heated rooms: every room wants its own temperature, and the installation must be tidy, reliable and expandable.
