Altering the value of the thermal differential
The factory settings envisage the device operating with a thermal differential of ± 0.2°C.
This thermal differential is suitable for systems with high thermal inertia, for example, systems

with cast-iron radiators.
Where the characteristics of the
system make it necessary to
change this value, proceed as
follows.
Activate manual operation mode
A.
Press button
; on the display,
in place of the temperature the
thermal differential value will
appear B.
Use buttons
to set the desired
differential (from ±0.1 to ±0.9) C.
