Specification scope: These values refer to the wired ARUNA HT260S 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.

Selection and wiring assessment — ARUNA HT260S

Installation footprint: The manufacturer-linked card gives 85mm / 125mm / 24mm for this wider rectangular 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 HT260S 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 HT260S 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 HT260S — prevent suffix-based substitutions

ARUNA HT260S has its own product record and cannot be assumed pin- or feature-equivalent to HT250S, although its catalog lists the same common battery, thermostat relay and setting bands. Obtain the selected unit’s control-interface details and confirm actual sensitivity in its operating manual. When the boiler input needs a voltage-free call for heat, follow the HT260S contact diagram rather than borrowing an RF thermostat kit’s receiver wiring.
