Temperature regulator Euroster E2026 programmable thermostat, model E2026

Euroster E2026 is a programmable wall-mounted temperature regulator intended for controlling central heating boilers and electric devices, with recommended use for underfloor heating systems. The device supports weekly programming with 10-minute resolution, four temperature levels and includes a running-time counter. An optimization module for heating curve adjustment is integrated to help maintain comfort while limiting energy consumption.

Advantages

The regulator offers precise temperature control with 0.2°C regulation accuracy and 0.1°C measurement resolution, multiple hysteresis settings, and a backlit LCD for clear readout. Battery-powered operation (2×AA) and a volt-free SPDT relay output enable flexible installation and compatibility with various heating systems. Compact wall-mounted design and a two-year warranty complete the feature set.

How to use

Mount the Euroster E2026 on a wall using the supplied fixing plugs and insert two AA alkaline batteries. Configure the weekly program with 10-minute resolution and set the desired temperature levels for each time block. Connect the device to the heating system using the volt-free SPDT relay output following the wiring instructions in the manual; use the hysteresis setting that best suits system responsiveness. Use the built-in heating curve optimization to fine-tune regulation for stable indoor temperature and reduced energy use.

Usage recommendations

Install the regulator away from direct sunlight, drafts and heat sources for accurate temperature measurement. Replace batteries promptly when indicated and follow the manual for relay wiring to ensure safe, reliable operation.
