BATTERY
The Chronothermostat is provided
with 2 battery thresholds: the first
threshold indicates that the batteries
are low and must be replaced.
In this condition, and with the display
in the off state, a flashing battery
icon will be seen every 5 seconds
After touching the Finder button and turning on the display, the battery icon
will continue to flash.
At the second threshold the Chronothermostat turns off, the output relay
will be set to OFF and it will no longer be possible to make any further
adjustments. In this condition the flashing battery icon can be seen every
5 seconds (until the batteries completely run out).
