General Life NORA HT10S RF

NORA 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: NORA
Model: HT10S RF
Category: Wireless room thermostat
Connection: Radio link to receiver; receiver relay to equipment

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.

NORA HT10S RF — electrical and control assessment

Room thermostat and receiver: Room unit dimensions: 85.7mm / 85.7mm / 33.5mm, supply: 3V DC (2 x AAA alkaline batteries). Receiver dimensions: 90mm / 90mm / 25mm, supply: 230V (AC). Unlike the battery room thermostat, the relay receiver’s mains connection requires qualified installation and protection.

Contact selection: Receiver NO ratings of 7A (240VAC – resistive load) 10A (120VAC – resistive load) must be compared with the actual heater/boiler thermostat input and its resistive or inductive nature. The same housing designation does not prove that a wired NORA HT10S RF sibling has an identical output.

Control and radio validation: The recorded setpoint band is (5°C) – (30°C) and operating sensitivity is 0.3°C. A sensitivity parameter does not specify installed measurement uncertainty. Verify controller heating cycles, radio pairing, battery-low indications, coverage through obstructions and behavior if link to the receiver is lost.

Documentation: Use the linked exact-model General Life record to confirm supplied receiver, wiring terminals and revision. Do not assume Wi-Fi/app support from the RF label.
