Setpoint range (manufacturer: Operating Temperature Range)(5°C) – (30°C)

Battery Life1 Year (2 x AAA)

Ambient operating temperature(-10°C) – (+50°C)

Storage Temperature(-20°C) – (+60°C)

Specification scope: These values refer to the wired ARUNA 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.

Selection and wiring assessment — ARUNA HT16S

Installation footprint: The manufacturer-linked card gives 85.7mm / 85.7mm / 30.1mm for this compact room thermostat, with a room-unit supply of 3V DC (2 x AAA Alkaline Battery). Confirm mounting clearance, service access, battery replacement and the actual cable entry when replacing a differently shaped wall control.

Contact and appliance interface: The quoted relay switching condition is 2A/30VDC (Resistive Load) 0.5A/125VAC (Resistive Load). A normally-open, resistive-load rating must be distinguished from powered control inputs and boiler/heat-pump requirements; never treat the contact as automatically suitable for a 230 V inductive load. Confirm the receiving device’s control-voltage and switching method before installation.

Setpoint and control behavior: ARUNA HT16S lists (5°C) – (30°C) for its selectable room setting and (-2.0°C) – (+2.0°C) as operating sensitivity. An adjustable negative-to-positive sensitivity span is not a stated measurement-accuracy band. Evaluate switching cycling and the heat source’s response time, especially if retrofitting a slow underfloor loop.

Revision check: Keep the ARUNA HT16S wired SKU separate from any RF receiver or SMART platform even if the series and faceplate resemble each other. This model-specific comparison uses recorded manufacturer fields; order-code details and approvals must be checked with the linked current official documentation.

ARUNA HT16S — same manual group, distinct SKU

The manufacturer groups ARUNA HT16S with HT15/HT15S in technical documents, but each thermostat remains a distinct product selection. The wired 3 V design offers temperature control through a boiler relay contact, not radio communication. Verify the actual control menu and setpoint/sensitivity settings, and compare the 30.1 mm enclosure depth against the wall location. A general spec-table measurement figure does not replace a whole-building temperature control accuracy test.
