The all new PRE5502e “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 PRE5502e combines both operational efficiency with guest comfort.

Designed to optimize energy savings with its unique three stage technology, the new PRE5502e combines both operational efficiency with automation thanks to its unique built-in 3 stage programming and secure temperature set-points. The PRE5502 has no user controls allowing full control of the unit, the unit can only be triggered into comfort mode when a 230V AC at 50Hz is applied to the unit remote trigger terminal. The PRE5502e can be pre-programmed to a wide range of temperature and time settings to suite all situations, and then locked, making the new PRE5502e 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.
