FUNCTIONS
MINIMUM AND MAXIMUM THERMOSTAT FUNCTION
This function is active with the device in both MANUAL and AUTOMATIC operating mode when the
probe is used to control the system water temperature. It allows the fan to be blocked until the water
temperature reaches the values suitable for the required regulation. This way, environmental comfort is
improved and consumptions are considerably reduced. Any system activation request in this situation is
indicated in the display with the "FLAME" symbol flashing (fig. 6G).
WINTER OPERATION: The fan motor is disabled when the water temperature drops below the value
pre-set for the P5 adjustable parameter (Default value 30°) with 3 °C hysteresis.
SUMMER OPERATION: The fan motor is disabled when the water temperature rises above the value
pre-set for the P7 adjustable parameter (Default value 20 °C) with 3 °C hysteresis.
In case of faults in the probe, the fan and solenoid valves are disabled. The display indicates error code
E03 or E04 depending on whether the probe is acknowledged as open or in short circuit.
This function is EXCLUDED if no water temperature probe is connected when the device is turned on.
TEMPERATURE UNIT OF MEASUREMENT SELECTION FUNCTION
The unit of measurement of the temperature can be modified from °C (default value) to °F and vice-ver-
sa by following the procedure described in paragraph " MODIFICATION OF OPERATING PARAMETERS".
