The all new PRE5004e “ecostat” is one of the next generation time and temperature limiting thermostats from the Prefect stable. Designed to optimize energy savings with its unique three stage technology, the new PRE5004e combines both operational efficiency with guest comfort.

The PRE5004e can be pre-programmed to a wide range of temperature and time settings to suite all situations, and then locked, making the new PRE5004e tamperproof, insuring that predicted energy savings are achieved. Prefect`s unique understanding of this market, influences the design of all our products, this is why the new “ecostat” range boasts local Infra-red programming via the PRE5901 Handset, so should there be a need to make a change to the times or temperatures, it can be achieved simply, quickly and securely. Alternatively for larger projects, we can factory pre-set your preferred settings at point of manufacture, thus insuring continuity, whilst reducing time on site. The all new PRE5004e Cleverly simple!
