Euroster 4020TXRX multifunctional temperature controller

New Euroster 4020TXRX temperature controllers with a large backlit display and programmable time-based reduction of the comfort temperature control the operation of the heat source. Thanks to the ability to work with two temperature sensors and the PWM function, they work optimally with underfloor heating systems.

Documentation

Minimalist design, reliability, and safety are the key advantages of the new Euroster 4020TX temperature controller. The large backlit display shows two temperatures: the set temperature and the current temperature. The controller effectively stabilizes the room temperature at the desired level, ensuring user comfort and real energy savings. A range of useful additional functions enhances the attractiveness and versatility of the controller, making it suitable for both households and public utility spaces. The controller also features a function that limits temperature adjustments by unauthorized users.

Receivers

The wireless controller is supplied as standard with an RX receiver. Optionally, 3 other receivers are also available, depending on requirements and installation conditions.

default receiver

RX receiver with a volt-free controlled output 5(3)A, installation in a 230V electrical socket

optional receiver

RXN

RXN receiver with a volt-free controlled output 5(3)A, wall-mounted installation

optional receiver

RX230
