Salus RX30RF Zigbee Smart Home Receiver 230V Dual Channel OpenTherm Boiler Zone Control
The Salus RX30RF is a 230 V mains-powered Zigbee receiver for the Salus iT600 / Smart Home ecosystem. It provides two independent relay-output channels that can be configured to control a single heating zone, two heating zones, or one heating zone plus domestic hot water — giving the same receiver the flexibility to serve combi boiler, conventional system and zone-valve installations without changing hardware.
A key feature is the built-in OpenTherm controller with auto-detection: when connected to an OpenTherm-capable boiler and paired with a compatible Salus thermostat (such as the Elypso EL600T), the RX30RF switches automatically from relay to digital modulation — letting the boiler continuously adjust its water temperature for the heat demand, rather than simply cycling on and off. Two operating modes — RX1 (boiler receiver — any zone calls) and RX2 (zone receiver — one specific thermostat calls) — are selected via an internal slider switch, and a manual override mode allows the output to be forced on or off without the Zigbee network for emergency use or commissioning.
Two independent relay outputs allow the same receiver to handle: a single CH zone; two CH zones with separate thermostats; or one CH zone plus domestic hot water. No swapping hardware for different system types.
The built-in OpenTherm interface auto-detects whether the boiler supports the OT protocol. When detected, it switches from relay to digital modulation — the boiler adjusts its water temperature continuously rather than cycling, reducing temperature overshoot and gas waste.
RX1 mode: any Salus thermostat in the Zigbee network can call this receiver on — used for the boiler or system pump. RX2 mode: only one specific thermostat activates this output — used for an individual zone valve. Both modes can coexist in one installation.
An internal slide switch changes between AUTO (Zigbee-controlled) and MANUAL (operator-controlled). In MANUAL, the output is forced on or off regardless of the network — useful during commissioning or if a thermostat battery fails.
Dual-colour LED indicators show at a glance whether the receiver is in AUTO or MANUAL mode, whether the output is currently active (green), and whether the Zigbee network is connected.
Works with radiator systems, wet underfloor heating manifolds, fan-coil units and zone-valve S-plan setups. Compatible with the full Salus iT600 / Smart Home thermostat and TRV range.

What is the difference between RX1 and RX2 mode?
In RX1 mode the receiver responds to a heating demand from any Salus thermostat in the network — typically used for the boiler or system circulator pump, where any zone calling for heat should start the boiler. In RX2 mode the receiver responds only to the specific thermostat it has been paired with — used for an individual zone valve that should only open when its own thermostat calls. Both modes can operate simultaneously using two RX30RF units on one gateway.
Will OpenTherm work with my boiler?
OpenTherm is supported by most modern condensing combi boilers from Worcester Bosch, Vaillant, Viessmann, Baxi, Ideal and others. The RX30RF auto-detects whether the boiler supports OT and switches modes automatically — no manual configuration needed. If the boiler is not OT-compatible, the receiver operates in standard relay mode and all zone-control features still work.
Which gateway does it need?
For full remote app control via the Salus Premium Lite app, pair the RX30RF with a Salus UG800 or UGE600 Universal Gateway connected to your router. For a local offline system (no internet), use a CO10RF coordinator instead. The RX30RF cannot operate autonomously without one of these coordinators.
What happens if the Zigbee network goes down?
Set the internal slider to MANUAL mode and use the bottom ON/OFF switch to control the output directly. This provides continuous heating until the network issue is resolved, without requiring any app access or thermostat involvement.
