General Life ILLONA HT340S RF

ILLONA HT340S 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: ILLONA
Model: HT340S RF
Category: Wireless room thermostat
Connection: Radio link to receiver; receiver relay to equipment

Room Thermostat Specifications

Dimensions (manufacturer order)85mm / 125mm / 20mm

Power supply3V DC (2 x AAA alkaline batteries)

Temperature measurement figure (manufacturer-reported)0.1°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 linked manufacturer document is titled “HT300S RF”. An exact match of series, model and published dimensions could not be established. Its data is not substituted for the model-specific RF product table; the correct manual and hardware revision remain to be confirmed.

ILLONA HT340S RF — electrical and control assessment

Room thermostat and receiver: Room unit dimensions: 85mm / 125mm / 20mm, 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 ILLONA HT340S RF sibling has an identical output.

Control and radio validation: The recorded setpoint band is (5°C) – (30°C) and operating sensitivity is check exact model. 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.
