General Life CERES HT16S RF

CERES HT16S 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: CERES
Model: HT16S RF
Category: Wireless room thermostat
Connection: Radio link to receiver; receiver relay to equipment

Room Thermostat Specifications

Dimensions (manufacturer order)85.7mm / 85.7mm / 30.1mm

Power supply3V DC (2 x AAA alkaline batteries)

Temperature measurement figure (manufacturer-reported)0.1°C

Operating sensitivity (manufacturer-reported)(-2.0°C) – (+2.0°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

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

Power supply230V AC

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

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.

CERES HT16S RF: model-specific RF commissioning notes

Physical split: The thermostat unit is 85.7mm / 85.7mm / 30.1mm and uses 3V DC (2 x AAA alkaline batteries); the supplied receiver is listed as 90mm / 90mm / 25mm with 230V AC. These are separate circuits; the room unit’s battery supply must not be connected to the receiver’s mains terminals.

Switch output: The receiver’s normally-open contact is stated as 7A at 240VAC; 10A at 120VAC under resistive conditions. Identify the building heating unit’s thermostat input, any needed isolation and inductive-load restrictions before using that relay to switch equipment.

Control behavior: The recorded room setpoint window is (5°C) – (30°C), with (-2.0°C) – (+2.0°C) sensitivity. A negative-to-positive setting range does not prove ±2°C sensing accuracy. Test actual RF signal quality, pairing, signal-failure response and manual receiver behavior at the installation site.

Order-specific checks: CERES HT16S RF RF is not interchangeable with the same series wired model purely by appearance. Verify exact receiver, electrical terminals and manufacturer revision in the linked official instructions.
