4.37.1 Temperature temporary change
A temporary change of the temperature can be performed using UP/DOWN arrow keys.
The change of the temperature will affect current time interval and all subsequent time intervals having the
same configuration. In any case, it will be valid only until 11pm.
The temporary change is indicated by the
blinking of modified time intervals
. A triangular icon will be di-
splayed above the current time interval: the point of the icon will be upward in case of temperature increase,
downward in case of temperature decrease.
The temperature can be changed with 0,3°C steps. To cancel the temporary change, set the temperature
value within the set range.
4.37.2 Chronothermostat status
The system chronothermostat have three status: active, non-active and antifreeze.
The active status can be changed using UP / DOWN arrow keys and then pressing ’1’ key repeatedly until
you reach the desired option.
-
Active status:
the chronothermostat activates the boiler according to the setup.
-
Manual setup status:
the chronothermostat activates the boiler according to a threshold set manually.
-
Non-active status:
the chronothermostat will never activate the boiler.
-
Antifreeze status:
time schedule set will be ignored and the chronothermostat will activate the
boiler in order to maintain a temperature value equal or above the antifreeze
thresholds.
Note: the chronothermostat manual setup can be selected via keypad or via SMS (with <T.#> message,
where <#> stands for the degrees with no decimals).
Note: the SMS command <T.ON> set the thermostat to automatic mode.
4.37.3 Boiler failure detection
This function detects possible failures or blocks of the system boiler.
The function generates a boiler failure event when environment temperature has not raised by at least
0.3 degree
after two hours of boiler working.
If the failure condition is not reset, a boiler failure event will be generated every 48 hours and the dialler,
when configured, will activate consequently.
