General Life MITRA HT10S RF

MITRA 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: MITRA
Model: HT10S RF
Category: Wireless room thermostat

Room Thermostat Specifications

Dimensions (H/W/D)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 (H/W/D)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 product table reports 0.3°C operating sensitivity. General hysteresis text describes a 0.5°C default; these descriptions should not be treated as equivalent specifications.

Wireless installation assessment — MITRA HT10S RF

Two electrical units: The MITRA HT10S RF room thermostat is 85.7mm / 85.7mm / 33.5mm and uses 3V DC (2 x AAA alkaline batteries), while its distinct receiver is 90mm / 90mm / 25mm and requires 230V (AC). Do not wire receiver mains into the battery-powered room unit or assume the thermostat can operate without its correct paired receiver.

Heating switching: The receiver’s published normally-open resistive load is 7A (240VAC – resistive load) 10A (120VAC – resistive load). The heat source must accept this contact topology and the selected receiver’s output wiring; a resistive rating is not an inductive pump or compressor switching certificate.

Wireless commissioning: Test radio pairing, communication reliability through the actual walls/floors, manual receiver control and safe response to a lost wireless link. The room setpoint is (5°C) – (30°C) and operating sensitivity is 0.3°C. A control sensitivity figure must not be confused with measurement resolution. Locate the sensor away from localized heating or drafts.

Variant boundary: This MITRA HT10S RF receiver-based product should not inherit a wired sibling’s low-voltage relay specification or a SMART app’s features. Confirm receiver serial/revision, radio pairing instructions, current maker diagram and boiler terminal scheme before replacement.
