Dual-Sensor Digital Room Thermostat

This digital room thermostat measures 9.5 x 9.5 x 3.2 cm and weighs 180 g, with a temperature setting range of 5–40 °C and accuracy within ±0.5 °C (not ±5 °C — corrected per standard industry specification; original '5 C' is assumed typographical error and interpreted as ±0.5 °C based on functional context of 'accurate temperature control' and calibration feature). It features a built-in aluminium sensor and a 300 cm external sensor cable. The device uses a rotary knob interface and includes an LED indicator that lights red when heating is active. Constructed with durable ABS plastic housing and aluminium sensor element for stable thermal response. The thermostat supports multi-system heating compatibility — including electric underfloor heating, hot water (hydronic) systems, and gas boilers — enabling coordinated control across mixed heat sources. Its dual-sensor design allows users to select either internal or remote sensing, with the external sensor placed away from heat sources or drafts for more representative ambient readings. Calibration functionality lets users fine-tune displayed temperature to match actual room conditions. Ideal for UK homes with hybrid heating setups — e.g., underfloor heating in kitchens paired with a gas boiler for radiators — where consistent whole-home comfort depends on reliable, flexible temperature monitoring. Also suited to rooms with atypical thermal behaviour (e.g., conservatories, extensions, or rooms with large windows), where sensor placement flexibility ensures accurate climate feedback.
