## Summary description

Olympia radiator thermostat HT 430-23A (MPN 73036) is an electronic white radiator control device designed to regulate heating. The unit provides temperature regulation for single radiators, featuring a compact body and user-friendly display-based control. Suitable for replacement or upgrade of radiator valve controls in residential and commercial heating systems.

## Long description

Olympia HT 430-23A radiator thermostat in white is an electronic controller designed to regulate the temperature of a single radiator. The compact unit measures approximately 60 mm wide, 59 mm deep and 100 mm high and comes as a single-piece device intended for replacement or upgrade of radiator valve controls in residential and light commercial heating systems. The thermostat uses a display-based menu for setting comfort and economy periods and supports individual daily schedules.
Advantages
The device offers a compact, near-silent drive mechanism that exerts minimal strain on radiator valves and fits in tight installation spaces. Menu-driven operation and a clear display make programming straightforward, with preset comfort and economy periods for fast commissioning. Several safety and convenience functions such as frost protection, window-open detection and a child lock enhance reliability and practical everyday use.
Suitable for (tasks / use cases)
Replacing a manual radiator valve head in an apartment or house
Upgrading single-room temperature control to electronic scheduling
Maintaining constant room temperature with frost protection during absence
Energy-saving regulation by setting comfort and economy periods per day
When it may not be suitable
The thermostat is intended for control of individual radiators and is not a central heating controller; it does not replace a boiler management system or a multi-zone building automation controller. It may not be suitable where wireless network integration or remote app control is required, since this model provides local, display-based programming only.
