30 - ENGLISH
• Precision of the reading in air conditioning mode:
- ≤ ±0,5 °C between +20 °C and +30 °C
- ≤ ±0,8 °C at the temperature extremes
• Software settings: possibility of compensating the temperature
reading with a software offset (± 3 °C max) to adapt the measure-
ment to the specific installation conditions
• Hysteresis: adjustable between 0,1 °C and 1 °C
• Thermostat operating range:
- +4 °C - +15 °C in antifreeze mode
- +5 °C - +35 °C in heating or cooling mode
• Clock accuracy: ≤ ±1 s a day
• Principal functions:
- hourly temperature settings in 20-minute steps
- 3 programmable temperature set-points for heating + 3 tempera-
ture set-points for cooling
- weekly programming
- 2 fixed programs and 2 user configurable programs (for both heat-
ing and cooling)
- possibility of overriding the program to vary the temperature
- programs retained even in the event of a power outage
- regulation for both heating and cooling systems
- antifreeze function
- possibility of timed switch off
- remote activation option via telephone dialler
- instructions in 5 languages (Italian, English, French, Spanish, Ger-
man)
- device reset
- self-diagnostic functions: automatically activated at regular inter-
vals during normal operation, to check the state of the temperature
probe, the state of the display driver, the efficiency of the EEPROM
memory, the efficiency of the backup stage
- button lockout function with 3-digit PIN number to prevent unau-
thorised access to all the thermostat functions and programs (for
example, when installed in a public place)
