• Page 17: 10 - Configuration menu (Installer) 10.4 - Type temperature adjustment methods The thermostat is factory set to work in modulating proportional (PrOP) mode, setting cycles from 7 to 20 minutes (default 7 minutes). This system maintains the desired temperature more stable, whilst increasing the user's comfort sensation and saving on energy consumption. A long cycle is recommended for systems with high thermal inertia and a short cycle for systems with low thermal inertia. As opposed to the modulating proportional, the temperature can be adjusted in thermal differential mode ON/OFF with a preset thermal differential value of 0.3°C (default). The hysteresis value must be set according to the system's thermal inertia; a low value is recommended for systems with radiators made of cast iron and a high value for systems with fan coils. 10.4.1 - Selection of the temperature adjustment mode (proportional or differential ON/OFF) From normal thermostat operation, access the menus by pressing and holding the Mode key. It will be possible to select temperature adjustment mode between modulating proportional (PrOP) factory setting or thermal differential (On:OFF).
