14. DIFFERENTIAL SETTING
The “differential” (∆t) is the difference between the room tem-
perature when the heating system “goes off”, and the room
temperature when it “comes on”again.
EXAMPLE:
Room temperature (heating system goes off) = 20°C
Room temperature (heating system comes on) = 19,8°C
∆t = 0,2°C
Two different differential values may be selected:
0,2°C (advi-
sable for water-circulating systems, for example “radiators”), or
0,8°C (advisable for air-circulating systems, for example “convectors”).
• Switch the selector on the desired position (fig.15).
15. KNOB LOCK
The “sun” knob, which sets the NORMAL temperature “T1”, may be locked, making it possible for the chronothermostat to be
used in public places, without anyone possibly changing the set temperature.
Ho
w to do it:
After opening the HOLE-CAP inside the base (fig. 16), remove the knob from its seat and replace it with the HOLE-CAP itself
(figs.17 e 18).
