SENNA HT301S: design-in and commissioning assessment

Package: The manufacturer lists 85mm / 125mm / 19mm (landscape-style wall placement) and a room control supply of 3V DC (2 x AAA Alkaline Battery). Check the cabinet or wall clearance, measuring location and access for its battery before replacing another series.

Electrical contact: The normally-open switching value is 2A/30VDC (Resistive Load) 0.5A/125VAC (Resistive Load) under the stated load condition. Determine the heat-source input type, electrical isolation, permitted cable and inductive-load requirements. A dry-contact relay rating is not blanket permission to drive motors or arbitrary 230 V equipment directly.

Settings: This SENNA HT301S record lists (5°C) – (30°C) for user setpoint adjustment and (-2.0°C) – (+2.0°C) operating sensitivity. Manufacturer control sensitivity is not a verified ±2°C measurement uncertainty. Review setpoint hysteresis, thermal inertia and heating on/off cycle at installation.

Exact model boundary: An RF receiver or connected SMART product under the same series name can have different electrical and connectivity requirements. Use the linked original General Life documentation for the delivered wired configuration.
