## Long description

Euroster E4020 is a wired daily temperature controller designed for time-programmed room heating control. The device supports a 24-hour schedule with multiple switching periods, allowing temperature setpoints to change automatically throughout the day. It connects by cable to heating systems or boiler controllers and is suitable for managing radiators, underfloor heating manifolds or central heating zones to maintain required indoor temperatures according to a daily timetable.
Advantages
