E817 Set-Back Tamperproof Thermostat + Timeout

Product Code: E817

The E817 Set-Back Tamperproof Thermostat regulates room temperatures to two different temperature setpoints, a lower temperature ‘Set-Back’ and a higher boost temperature ‘Setpoint’. A pushbutton on the side of the unit allows the user to select between the two levels, while LED indicators illuminate to clearly identify which mode the unit is in.

In addition to this set-back functionality the E817 incorporates a timeout while in the high/boost mode. It automatically reverts back to regulating the temperature to the lower ‘Setback’ mode after the pre-selected timeout period (anything between 0.25 and 8 hours) has expired, thus helping to reduce overall energy consumption.

Full adjustment of the two temperature levels and timeout can be achieved only through adjusting internal thumbwheels located inside the tamperproof unit, so preventing unauthorised modification to the thermostat’s configuration.

Additional delay periods can easily be accommodated, please call our sales team for further information on our customisation service.
