Setting and integral proportional thermal differential
This type of adjustment lets the programmable thermostat reduce system running times as the room
temperature approaches the set temperature, thus substantially reducing consumption while maintaining
excellent comfort .
Integral proportional adjustment has the advantage of letting you manage a wider variety of systems with
respect to the setting of the thermal differential, and it is especially suitable for floor and radiant systems .
The difference between the set temperature and the ambient temperature is just a few tenths of a degree .
This ensures more precise adjustment .
You can select three preset programmes based on the type of system to adjust (PI 1, PI 2 and PI 3) as shown
in the table .
Programme Cycle duration Minimum ON time Proportional Range Type of system
PI 1 10 minutes 1 minute 1 .5 °C
Base for gas burner, fan coil units,
zone valves, aluminium radiators
PI 2
5 minutes 1 minute 1 .5 °C Electric radiators
PI 3 20 minutes 2 minutes 1 .5 °C Radiant or floor systems, cooling
