General Life SENNA HT10S RF

SENNA HT10S RF is a General Life wireless room thermostat. The room unit communicates with a separate RF receiver, which switches compatible equipment through its relay.

Model Identification

Manufacturer: General Life
Series: SENNA
Model: HT10S RF
Category: Wireless room thermostat

Room Thermostat Specifications

Dimensions (manufacturer order)85.7mm / 85.7mm / 33.5mm

Power supply3V DC (2 x AAA alkaline batteries)

Temperature measurement figure (manufacturer-reported)0.1°C

Operating sensitivity (manufacturer-reported)0.3°C

Setpoint range(5°C) – (30°C)

Battery life (manufacturer-reported)1 year (2 x AAA)

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

Storage temperature(-20°C) – (+60°C)

Receiver Specifications

Power supply230V (AC)

Dimensions (manufacturer order)90mm / 90mm / 25mm

Relay NO switching current (resistive load)7A (240VAC – resistive load) 10A (120VAC – resistive load)

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

Storage temperature(-20°C) – (+60°C)

Specification scope: These values apply to the RF configuration. The thermostat and receiver have different power supplies. The receiver’s mains supply must not be confused with the equipment’s thermostat input. Relay ratings are for resistive loads. The 0.1°C measurement figure is manufacturer-reported and does not establish an independent ±0.1°C accuracy claim.

Compatibility and Installation

Confirm that the heating or cooling equipment supports the receiver’s on/off relay connection, and follow the exact equipment and thermostat manuals. The RF link replaces the cable between room unit and receiver; the receiver still needs power and an equipment connection. Electrical installation should be performed by a qualified installer.

Source and Revision Notes

The technical table reports 0.3°C operating sensitivity, while general hysteresis text describes a 0.5°C default. These manufacturer statements should not be treated as equivalent specifications.

Radio and switching integration — SENNA HT10S RF

The SENNA HT10S RF temperature controller’s listed size and supply are 85.7mm / 85.7mm / 33.5mm and 3V DC (2 x AAA alkaline batteries), respectively. Its separate 90mm / 90mm / 25mm receiver uses 230V (AC). Plan location, radio propagation, pairing and safe mains wiring independently.

Receiver normally-open switching is 7A (240VAC – resistive load) 10A (120VAC – resistive load) for the quoted resistive loading. Compare output type and voltage with the boiler’s input requirements; this figure is not a motor contactor or direct compressor-start rating.

The user setpoint range is (5°C) – (30°C) and operating sensitivity is 0.3°C. These fields govern control setup, not an independently verified temperature error specification. Test fail-safe reaction to battery depletion, RF loss and communication failure.

The supplied receiver/order revision determines electrical installation. Do not transfer RF figures to a wired or internet-connected sibling without the current model manual.
