Hysteresis Of The Differentials - Ariston ELIOS 25 Manual

limited to the value of the Maximum Temperature +5°C.
To lower the Safety Temperature, it is rst necessary
to decrease the Maximum Temperature and then set the
Safety Temperature to the desired value.
If the Safety Temperature is displayed but the relevant
Maximum Temperature is not, then the Safety
Temperature will be limited according to the highest
Maximum Temperature operating in the current
scheme (i.e. in scheme no.6, the value of the TS2 safety
temperature will be limited according to the value of the
TM3 maximum temperature if this is higher than TM4).
Should the hydraulic scheme be changed and SCH5
scheme previously activated, all the Safety and Maximum
temperatures will be set at the factory-set default values

WARNING!
It is not possible to set the Differential to a value lower
than the relevant hysteresis because the value of the
Differential is limited to the value of the hysteresis
+1°C. To lower the Differential it is rst necessary to
decrease the value of the hysteresis.
