## Long description

Euroster E4020TXRX wireless room temperature controller in white is a compact wall-mounted thermostat designed for remote regulation of indoor heating. The device consists of a user interface unit and a separate receiver that communicate wirelessly to control boiler or actuator operation according to selected temperature setpoints and schedules. The thermostat supports daily comfort and setback temperature programming and is intended for use in residential heating systems where simple wireless control and energy management are required.
Advantages
This wireless thermostat offers straightforward temperature control without the need for wiring between the room unit and the receiver, simplifying installation in existing interiors. The white housing provides a neutral appearance that fits common home decor. Programmable setpoints and schedule capability enable consistent temperature maintenance and contribute to more efficient energy use. The separate receiver isolates the heating control interface from the room sensor, allowing flexible placement and reducing visible components in living spaces.
Suitable for
Control of domestic boilers and heating zones in apartments or houses
Retrofit projects where hardwiring a thermostat is impractical
Rooms requiring daily temperature scheduling for comfort and energy savings
Integration with basic actuator or relay-controlled heating systems
Key specifications
Form factor: wall-mounted room thermostat
Operation: wireless communication between room unit and receiver
Color: white housing for unobtrusive installation
Functions: room temperature setpoint adjustment and daily scheduling
Control output: receiver drives boiler or actuator via relay/command signal
Intended use: residential heating systems and zone control
How to use
Mount the room unit at a representative location in the living area away from direct sunlight, drafts, or heat sources. Install the receiver near the boiler or actuator and connect it to the heating control input according to the system wiring diagram. Pair the room unit and receiver following the manufacturer's pairing procedure, then set the desired temperature setpoints and daily schedule through the thermostat interface. The thermostat will transmit setpoints to the receiver, which switches the heating system on or off to maintain the selected temperature.
Usage recommendations
For accurate temperature control position the room sensor at chest height on an interior wall and avoid locations near doors, windows or kitchen areas. Use setback periods during absence or nighttime to reduce energy consumption, and verify wireless signal strength between the room unit and receiver during installation to ensure reliable operation.
