6.3) TEMPERATURE DIFFERENTIAL (ON/OFF)
The chronothermostat is set (in factory) to work
with a
Differential mode ON/OFF
preset differential value of
.
0.3°C
The differential value must be set according to the system's thermal inertia.
A low value is recommended for systems with radiators (e.g. cast iron) and a
high value for systems with fan coils.
The differential value may be displayed and changed as follows:
•
Keep
pressed until the existing differential value blinks on the display
t1
(example in fig. 36 - factory setting
).
0.3C
•
Modify the value (from 0.2 to 0.7) using the keys (example in fig. 36).
•
Press
the desired value is obtained to return to program operation
OK twice
(example in fig. 37).
This function can be protected by a password (see chapter ).

Very low differential on/off values (for example 0.2°C) may
result in increased frequency of control transmission to the
receiver, resulting in more rapid battery depletion with
respect to data stated.

If for any reason the thermostat must be installed in a position where the detected
temperature can be affected (e.g. an external wall, which is generally colder than
the rest of the house in winter), an Offset value (correction value) can be set for the
detected room temperature.
Correction can be set from -1.9 to 1.9°C (factory setting 0.0).
