ADJUSTMENT LOGICS:
The thermostat operation (either cooling or
heating) takes place with a difference of 0,2°C
from the set point of the controller (Fig. 6). The
thermostat switches on the fan and opens the
valve (if any).
Ventilation is activated (limited to 2 minutes
every 8 minutes) and forced without a real ne-
cessity only with the following setting: cooling
mode and remote air probe; this is due to the
fact that in this situation a good air temperature
detection is possible only if the air is periodically
moved.

The water consent to ventilation (only if the
water probe is connected) is driven by the ac-
tivation and deactivation logic reported in fig-
ure 7; in case of FWEC4T and FWEC10 the water
consent to ventilation is active only in heating
mode.
In the FWEC10 version the fan speed can be
setted manually (like FWEC2T and FWEC4T) or
working automatically according to distance
between room temperature and temperature
SET (Fig.8).
