Specification scope: These values refer to the wired GAIA HT16S only. RF and SMART versions have separate receiver, power and connectivity requirements. The manufacturer’s 0.1°C measurement figure is reproduced as reported; it is not an independently established ±0.1°C accuracy claim. Check the current manual and exact variant before installation.
Document revision: The current product pages and the shared HT15 / HT15S / HT16S manual report different case depths (30.1 mm and 33.65 mm respectively). The dimensions above follow the linked source. Compare the shared manufacturer manual and confirm the exact hardware revision before installation.

Model selection and commissioning — GAIA HT16S

Dimensions and supply: GAIA HT16S has a manufacturer-listed 85.7mm / 85.7mm / 30.1mm housing (compact-style). Room-unit supply is 3V DC (2 x AAA Alkaline Battery). Verify wall coverage, cable exit, battery accessibility and clearance from sources of hot/cold air before mounting.

Relay compatibility: The exact wired profile gives 2A/30VDC (Resistive Load) 0.5A/125VAC (Resistive Load) for the normally-open contact. These resistive ratings cannot be used as a universal motor/boiler starting-current rating. Identify the heating unit’s voltage-free versus powered thermostat input and the correct contact circuit before connection.

Control setup: The recorded room setpoint band is (5°C) – (30°C); operating sensitivity is (-2.0°C) – (+2.0°C). This setting span is not a measurement-accuracy band; investigate permitted hysteresis and programmable control behavior in the current manual. Confirm heat-source cycling response and suitable room placement.

Not interchangeable by name: A sibling GAIA HT16S RF or SMART configuration can use a separate receiver or different control interface. Do not infer its voltage or programming functions from this wired model. The linked original General Life page remains the source for the exact revision.
