7. CHANGING THE BATTERY

The average lifetime of the batteries is 1 year, but frequent use of the back-
ground light may shorten this time considerably. If the
battery voltage appears on the display, the batteries should be replaced (see
Section 2.1). The exact time should be set again after the batteries have been

By pressing the "RESET" button located on the main panel of the thermostat,
the thermostat can be reset to its factory default settings. This results in

new program, as described in Sections 2 and 3.
