Configurable per SMS or with a mobile application. A password protects the system against unauthorized access.
Information reforwarding without further configuration needed.
Temperature window alarm with external temperature probe (temperature range from -25° C to 85° C).
Three modes of alarm reset available:
  • Forced mode: keeps the last fired alarm fixed
  • Timed mode: limits the number of alarm messages sent
  • Automatic mode: the alarm is automatically reset when the temperature is back within the valid range
Light indicator of fired temperature alarm.
Temperature alarms can be configured to activate the siren for a given time or to keep it active till the alarm is manually reset.
Supply failure and recovery alarm. A timed delay may be programmed so that the alarm does not fire immediately.
Temperature probe failure alarm. It is fired whenever the probe is disconnected or fails
Adjustable thermostat hysteresis. Heat anc cold modes possible.
Two voltage free switch inputs for the manual control of the relays.
Built-in programmable switch to reset the alarms.
Built-in switch for memory reset. A system memory reset restores default values, such as the default access password.
