Description
The Heatit DIN Thermostat is a compact and professional thermostat developed for DIN-rail installation inside electrical switchboards. Designed to manage electrical heating systems with high accuracy, it supports both residential applications such as underfloor heating and more demanding industrial environments.
Its robust design allows it to operate with a wide temperature range, making it suitable for everything from standard indoor heating to cold-storage or frost-protection systems. The unit features an intuitive front-panel interface and accepts two external NTC sensors, allowing installers to monitor room and floor temperatures simultaneously.
With ZeroX relay technology, the thermostat switches the load at the optimal moment (0 volts), reducing wear on the heating elements and extending their lifespan. Thanks to its DIN-rail mounting format and compact size, it integrates easily into new or existing electrical installations.
