b) Configuration
In this example of reversible installations, configure the thermostat
as “automatic” function (refer to the configuration pages at the
beginning of the guide). The thermostat will manage activation
of the heating or air conditioning by comparing the ambient
temperature with the setpoint temperature. The difference from
paragraph 5.2 is that activating the fan outputs will have no impact
on the installation. Depending on whether or not people are
present, the mode should alternate between
COMFORT
(presence)
or
ECO
(absence), or even
FROST PROTECTION
(long absence).
