Horstmann Mains Electronic Room Thermostat Tamperproof HTT4

Secure HTT4 — 230V Mains Operated Tamper-Proof Electronic Room Thermostat

The Secure HTT4 is a mains operated, tamper-proof electronic room thermostat designed for public areas and applications where user adjustment of temperature is not required or desirable. Based on the proven HRT4-A platform, it combines modern energy-saving control technology with robust Secure design, making it ideal for multi-occupancy buildings and commercial or domestic heating systems.

Tamper-Proof Temperature Control for Shared Spaces

Designed specifically for environments such as rented properties, care facilities and communal areas, the HTT4 prevents unauthorised temperature changes while maintaining comfortable and consistent heating. Load compensation technology reduces temperature swings commonly associated with older mechanical thermostats, improving comfort and efficiency.

Energy-Efficient and Boiler Plus Ready

When used alongside a suitable time control, the HTT4 is Boiler Plus compliant, helping installers meet current efficiency regulations. Its accurate temperature control can deliver energy savings of up to 10% compared with traditional thermostats, making it a smart upgrade for new installations or system refurbishments.

Installer-Friendly Design and Broad Compatibility

The HTT4 is easy to install thanks to an industry-standard wall plate and standard fixing centres. It is compatible with most domestic gas, oil and solid-fuel heating systems that respond to a 230V on/off control signal, and works seamlessly with Secure programmers and zone valves.
