By adjusting the temperature differential, the system can be pre-
vented from continually switching on or off; systems with high thermal
inertia (for example, with cast iron radiators) require a low temperature
differential value, and systems with low thermal inertia (for example,
fan coil units) require a higher value.
Example:
If the ambient temperature is set to 20 °C and the tem-
perature differential is set to 0.3 °C, the system will come on when
the ambient temperature falls to 19.9 °C and will go off when it
reaches 20.3 °C.
Press the
selection button on
THERM DIF
and, using the rotary
knob, set the desired value (can be selected between 0.1 °C and
1°C); lastly press the
selection button to confirm.
