Salus Elypso EL600F Smart Thermostat Zigbee 3.0 Rechargeable UFH Radiator Heating Cooling
The Salus Elypso EL600F is a Zigbee 3.0 smart thermostat with a built-in 750 mAh rechargeable Lithium-Ion battery — no mains wiring, no AA cells to replace. A 65 mm circular aluminium body with a matt glass face and a central rotating dial makes it as much a design statement as a heating control. The supplied charging dock doubles as a desktop stand and activates always-on display mode when the thermostat is placed on it, keeping the current temperature visible at all times. For wall mounting, both circular and square bezels are included in the box.
Via the Salus Premium Lite app and a UG800 or UGE600 gateway (sold separately), the EL600F controls underfloor heating, wet radiator systems, electric heating and cooling — pairing with up to 16 TRV3RF super-quiet radiator valves for room-by-room coordination, and with the RX30RF dual-channel receiver to call the boiler or heat pump. Optimum Start/Stop, landlord lockout, temperature calibration and email/text alerts are all included. Boiler Plus compliant. Software support guaranteed to 31 December 2030.
The integrated 750 mAh Li-Ion battery means no mains cable run to the thermostat location and no disposable batteries to replace. The dock charges it overnight via USB-C — just place it on the dock when not in use.
The supplied dock is a desktop stand and battery charger in one. When the thermostat sits on the dock, it switches to always-on display mode — the current room temperature is permanently visible, making it ideal as a shelf or mantlepiece unit rather than a wall-mounted control.
Pair up to 16 TRV3RF super-quiet smart radiator valve heads with a single EL600F for room-by-room coordination. When combined with an RX30RF receiver, the thermostat can automatically call the boiler when any paired TRV needs heat.
One thermostat model covers underfloor heating (KL08RF / CB12RF wiring centres), wet radiator systems (TRV3RF valves + RX30RF), electric heating and cooling — configurable in the app to match the installed system type.
The thermostat calculates how early to start heating so the room is at setpoint at the scheduled time, not after it. Optimum Stop cuts heating early based on the same thermal model to avoid overshoot and reduce wasted gas or electricity.
Lock the thermostat to a permitted setpoint range via the app — ideal for rental properties. Email and text alerts notify the owner of temperature exceedances, connectivity loss or other events, without requiring on-site attendance.

What else do I need to make it work?
At minimum: a Salus UG800 or UGE600 Universal Gateway. For boiler or heat pump control: an RX30RF dual-channel receiver (RX10RF is not compatible). For UFH: a KL08RF or CB12RF wiring centre. For radiator room control: TRV3RF radiator valve heads (up to 16 per EL600F thermostat). All available from Quality Heating.
How long does the battery last?
SALUS Controls does not publish a specific on-battery runtime figure — battery life depends on Zigbee traffic and how often the display is woken. In practice, most users charge the thermostat nightly or every few days using the dock. The always-on display mode is only active when the thermostat is physically on the dock — off the dock, the display sleeps between interactions, conserving battery.
Can I use it for cooling?
Yes — the EL600F supports both heating and cooling modes when used with compatible Salus Smart Home equipment, such as a fan-coil unit interfaced through the smart home system. The mode is selected in the app or via the rotating dial menu on the thermostat.
What happens if my internet goes down?
The EL600F supports offline local mode — paired TRV3RF valves and the RX30RF receiver continue operating over Zigbee without cloud access, running stored schedules. Full app and cloud features return automatically when internet connectivity is restored.
How does landlord lockout work?
Via the Salus Premium Lite app, lock the thermostat to a permitted temperature range — for example 16–22 °C. Tenants can adjust the setpoint only within those limits using the dial or app, and cannot access settings or schedules outside the permitted band. Alerts notify the landlord if temperatures exceed agreed limits.
