In connection with the built-in Timer,
the thermostat can be programmed
to lower the temperature (LO), e.g.
during the night.
The range is 0ºC to -15ºC.
Turn to choose economy set-back
level, and press ...
(Choose -5ºC if the temperature must
be lowered 5 degrees).
If normal room heating is installed we
recommend not to lower the tempera-
ture at night with more than approx.
-5ºC.
