Timeguard Digital Room Thermostat With Night Set-Back - TRT033N

The Timeguard TRT033N is a modern digital room thermostat designed for precise temperature management and enhanced energy-saving control. Featuring a clear illuminated display and easy “+ / –” push-button settings, it allows you to adjust the set-point quickly and view the current room temperature at a glance. The unit supports a standard supply voltage of 230 V AC at 50 Hz, with voltage-free changeover contacts rated at 3 (1) A for reliable integration into a wide range of heating systems.

Beyond standard thermostat functions, the TRT033N incorporates intelligent energy-management features: a built-in night set-back mode that reduces the set temperature by approximately 4 °C for between 1 to 9 hours, and a frost-protection mode that activates below 5 °C to safeguard pipework and systems. The set temperature range extends from 10 °C to 30 °C in 0.5 °C steps, and a rear DIP-switch allows selection of temperature swing (0.5 °C or 1 °C) and PID control for enhanced stability.

Installation and practicality have been carefully considered. The thermostat is surface-mount with wall plate included, and is powered by 2 × 1.5 V AA batteries (supplied) to drive the display and memory functions. The compact dimensions of 90 × 95 × 30 mm make it suitable for standard wall locations, and the unit is backed by a 3-year manufacturer guarantee, offering confidence for both domestic and commercial HVAC applications.
