How to Exit ECO Mode

To exit ECO mode, simply press the green
ECO button again. ECO will disappear
from the display and the thermostat will
control to its previous set temperature.

Changing the DT92E Installer Parameters

The DT92E has a special Installer Mode where some features can be adjusted to suit
your lifestyle or preferences – these are called Installer Parameters, and are listed in
the table below, along with a description of the options that are possible.
Your installer should set this up for you to suit your application (see CONFIGURATION
& SERVICE DATA section). However, you may wish to alter some of the settings
yourself, and this section shows you how to do this.
