Specification scope: These values refer to the wired NORA HT15 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.

NORA HT15: practical control selection

Housing and power: NORA HT15 records 85.7mm / 85.7mm / 33.65mm (shared user manual) dimensions and 3V DC (2 x AAA Alkaline Battery) supply. Compare the wall opening, battery access and permitted sensing location before replacing an older thermostat; a wired heat-source connection does not imply mains power to this faceplate.

Electrical design-in: Normally-open relay switching is listed as 2A/30VDC (Resistive Load) 0.5A/125VAC (Resistive Load). Test compatibility with the receiving heating controller’s contact voltage and load type. Resistive current values are not permission to switch inductive motors or a 230 V boiler input without a matching schematic.

Control response: The setpoint span is (5°C) – (30°C) and the operating sensitivity is (-2.0°C) – (+2.0°C). A sensitivity adjustment range is not evidence of a corresponding measurement error bound. Verify commissioning hysteresis and cycling against the actual plant.

Order-scope check: Keep this wired NORA HT15 separate from RF receiver and SMART variants; radio, firmware, relay and power assumptions must be checked on the correct General Life documentation.
