The TOA is an electronic thermostat (temperature monitor) for NTC temperature sensors with outputs for 230V or 24 V AC/DC actuators.
The thermostat can work for heating or cooling applications. If the measured temperature exceeds the temperature limit, the thermostat switches off its output. If the temperature returns to within the allowed limit, the output is switched back on.
The temperature limits can be adjusted by the user using a operating terminal if required.

    Control of damper for temperature control in an elevator shaft by opening or closing the motorized dampers (with spring return).
  • Frost protection
    Activating a heating device if temperature gets close to freezing.​​​​​
