2-Wire Programmable Heating Thermostat

Slim 86 x 86 x 28 mm surface-mount thermostat, designed for UK-standard 2-cable heating circuits. Powered by two AA 1.5 V batteries (not supplied), enabling flexible placement on any interior wall. Temperature measurement range: 5°C to 99°C; setpoint range: +5°C to +35°C; accuracy: ±0.5°C. Illuminated LCD presents both ambient and target temperatures side-by-side for instant verification. Programming flexibility includes six distinct time-and-temperature segments for Monday through Friday, plus two for Saturday and Sunday — supporting realistic UK occupancy patterns such as early-morning warmth, daytime economy mode, and evening comfort. Anti-freeze protection maintains +5°C minimum automatically, preventing frozen pipes in poorly insulated spaces or during sudden cold snaps. Relay output is potential-free with 3 A rating, compatible with most 2-wire-compatible heating actuators and controllers. Mounting involves only two screws and two wire connections. Configuration uses logical menu navigation with contextual prompts, supported by bilingual instructions and an official brand walkthrough video — making it accessible for non-technical users across all age groups.
