Fan settings
For optimal performance
the fan setting would
be on ‘Auto’—fan is
controlled by the system, i.e.
only comes on when the system
is heating the house. When the
thermostat is running the fan, the
fan blade symbol appears next to
‘Fan’ on the screen to indicate the
thermostat has the fan on.
There are additional fan settings
that can be programmed.
-
Lo
, fan is continuously on low.
Depending on the installation,
in some instances better
heating can be achieved with
the fan running continuously
on low—can help reduce cold
spots.
-
Med
, fan is continuously on
medium.
-
Hi
, fan is continuously on high.
Changing the fan setting
1. Press ‘System & Fan’.
2. Press ‘Fan’.
3. The current setting will flash,
use the up/down keys to shift
between Lo, Med, Hi, and Auto
modes.
4. Press ‘Done’ to save the
setting.
Changing the fan to circulate air
on a hot day
If you want air to circulate through
the house on a hot day do the
following:
1. Press ‘System & Fan’.
2. Use the up/down keys to
toggle between ‘Heat’ and
‘Off’, select the off setting
(‘Off’ will flash).
3. Select ‘Fan’ and use the up/
down keys to toggle between
the fan settings and select the
desired fan speed. The screen
display would look similar
to that shown below—fan
symbol would also display.
Remember this is a manual
override of the system so if you
want to stop the fan you will need
to go back into the fan menu and
change ‘Fan’ back to auto.
