## Summary description

Euroster 4040TXRX is a wireless room temperature regulator consisting of a thermostat transmitter and a receiver socket. It controls heating by maintaining set temperature levels, supports wireless communication between transmitter and receiver, and is designed for easy installation in residential or small commercial spaces to regulate radiators or electric heaters.

## Long description

Euroster 4040TXRX wireless room temperature regulator includes a battery-powered thermostat transmitter and a plug-in receiver socket designed to control electric heaters or radiator valve actuators via switching the connected load. The device maintains target room temperature by measuring ambient conditions at the transmitter and communicating setpoint and control commands wirelessly to the receiver. The system is intended for straightforward installation in residential and small commercial environments where local temperature regulation and wireless control are required.
Advantages
The Euroster 4040TXRX provides wireless communication between thermostat and receiver, removing the need for additional wiring and simplifying retrofit installations. It offers programmable temperature setpoints and stable regulation to reduce temperature fluctuations. The compact receiver socket design allows direct connection to standard mains outlets, while the transmitter’s user interface enables simple adjustment of target temperature. The combined solution suits both radiator and electric heater control depending on the wiring and actuator used.
Suitable for
 Controlling electric heaters or convectors in individual rooms
 Retrofit temperature regulation in apartments and houses without thermostat wiring
 Local temperature control for home offices, bedrooms, and living rooms
 Small commercial rooms where separate room control is needed
Key specifications
 Wireless thermostat transmitter plus plug-in receiver socket
 Room ambient temperature sensing by the transmitter
 Setpoint adjustment via transmitter controls
 Receiver suitable for direct connection to mains outlet and switching of heater load
 Compatibility with radiator actuators or electric heater elements depending on installation
 Designed for residential and small commercial use
How to use
Install the receiver into a nearby mains outlet and connect the heater or actuator to the receiver output according to the heater manufacturer’s wiring instructions. Place the thermostat transmitter in the room where temperature control is required, away from direct sunlight and heat sources to ensure accurate ambient measurements. Set the desired temperature on the transmitter interface; the transmitter will communicate wirelessly with the receiver to switch the connected load on or off to maintain the selected temperature. Consult the supplied manual for pairing steps and any configuration options such as temperature offsets or control modes.
Usage recommendations
Position the transmitter at typical occupant height and not directly above or below heat-emitting devices for accurate readings. When used with radiator valve actuators, verify compatibility and, if necessary, use the receiver with an appropriate actuator interface. For safety, follow local electrical regulations when connecting the receiver and ensure the connected heater does not exceed the receiver’s rated load.
