General Life ILLONA HT110S RF

ILLONA HT110S 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: HT110S RF
Category: Wireless room thermostat
Connection: Radio link to receiver; receiver relay to equipment

Room Thermostat Specifications

Dimensions (manufacturer order)85mm / 125mm / 24mm

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) – (35°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 “HT100-RF – HT100S-RF – HT110S-RF ENG – TPI”. 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.

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.

Installation decisions for ILLONA HT110S RF

Separate radio and relay units: The mobile room unit is 85mm / 125mm / 24mm and has 3V DC (2 x AAA alkaline batteries) supply; the receiver is 90mm / 90mm / 25mm and accepts 230V (AC). Do not mix up their wiring and electrical-safety duties. The room thermostat must be situated where it measures representative air temperature, while the mains-powered receiver needs safe access and wiring.

Contact capacity: The receiver’s normally-open relay is shown as 7A (240VAC – resistive load) 10A (120VAC – resistive load) at the indicated resistive load. Check heat-source on/off input type, wire insulation and any external power/inductive load rather than assuming this family rating applies to every boiler.

Temperature and RF commissioning: ILLONA HT110S RF lists (5°C) – (35°C) as its setpoint span and 0.3°C as its operating sensitivity. The control sensitivity is distinct from the quoted measurement resolution. Test actual radio range, pairing, power-loss and lost-communication behavior with the delivered receiver.

Product scope: Compare any wired or app-enabled sibling as a separate ordering variant, not a guaranteed compatible replacement. Manufacturer model-sheet, firmware/receiver version and terminal diagram remain definitive.
