11. CHANGING THE BATTERY
When the screen shows the symbol
the unit warns the user that the batteries
have limited energy and that they must be
replaced in the next 3 weeks. To replace the
batteries simple remove the cover (photo 2)
to expose the battery compartment. Take
care of the battery orientation and insert the
new batteries according to the graphic
representation etch on the plastic base.
The reverse installation will not harm the
device, but it will permit it to operate.
The battery life time has been design to be
approximately 3 years. Factors that
influence the battery life are prolong use of
the keyboard with the backlight active, low
temperature and high humidity as well as
battery quality. When you remove the
batteries, the device will operate normally
for 30sec without losing time-date settings.
If the room, in which the thermostat is
installed, falls below 5°C, the unit activates
the burner output irrelevant of the ON or
