Available in Tamperproof (230V/24V) and Standard Accessible (24V)

Product Overview

The DT-340 is a versatile range of surface-mounted dial thermostats designed for the specific demands of commercial and multi-occupancy buildings.

The range offers two distinct control philosophies:

1. Tamperproof (230V & 24V): For "safety-conscious" environments like Student Accommodation, Care Homes, and public areas where preventing unauthorised adjustment is critical.
2. Standard Accessible (24V): A non-tamperproof option for areas where end-user adjustment is required, but low-voltage integration is necessary.

Both variants feature a robust surface-mount chassis that eliminates the need for a recessed back box, making them the ideal retrofit solution for upgrading older commercial heating systems.

Technical Features & Benefits

• Secure Tamperproof Models (230V/24V): The cover is secured by robust integral clips that require a flat-head screwdriver to remove. The set-point dial is concealed underneath, preventing unauthorised adjustment and protecting energy efficiency targets.
• Accessible Control (24V Non-Tamperproof): Available as a standard adjustable unit for 24V applications, allowing users to adjust temperature comfort directly via the external dial.
• Rapid Commercial Retrofit: Designed with a low-profile chassis for direct wall mounting. This removes the need for chasing out walls or installing flush boxes, significantly reducing installation time in refurbishment contracts.
• Advanced Sensing: Features a precision internal air sensor plus a facility for a Remote NTC Sensor (4k7 Ohm @ 25°C), allowing for remote monitoring or floor temperature limiting.

Instant Diagnostics: Includes a high-visibility Red LED Call-for-Heat indicator, providing immediate visual feedback for maintenance teams during fault finding or routine inspections.

Product Description
The DT-340 Range is the professional choice for commercial heating control, balancing occupant comfort with facility management requirements.

For landlords and facility managers, the Tamperproof variants (available in both mains 230V and low-voltage 24V) provide "lock-down" energy security. The temperature dial is hidden behind a removal-resistant cover, ensuring that heating schedules and set-points cannot be tampered with by transient occupants.

For low-voltage applications requiring user autonomy, the 24V Non-Tamperproof model provides the same rugged reliability but with an accessible interface for easy adjustment.

Whether controlling single UFH zones or integrating with commercial BMS strategies, the DT-340 offers a straightforward, "install-and-forget" solution. Its surface-mounted design allows for rapid deployment on any substrate, while the remote sensor capability provides flexibility for complex room layouts.
