TOA Thermostat for elevator shaft ventilation for 230 VAC or 24 V AC/DC actuators

The TOA is an electronic thermostat (temperature monitor) preconfigured for elevator shaft ventilation with outputs for 230 VAC or 24 V AC/DC spring return actuators. 
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 thermostat can work for heating or cooling applications. The TOA is delivered with a maximum temperature limit of 35°C
(95 °F) and an allowed limit of 30 °C (86 °F). 
The thermostat is preconfigured for lift shaft ventilation, but can also be used for heating or cooling applications.

It can be adjusted by the user using the OPA-S operating terminal if required.
Note: The temperature sensors are not included with the thermostat. These can be ordered under accessories as internal or remote sensors.

Applications

• Ventilation damper control for elevator shafts.
  Control of damper for temperature control in an elevator shaft by opening or closing the motorized dampers (with spring return). Turning the contact off opens the damper, turning the contact on closes the damper.
• Frost protection
  Activating a heating device if temperature gets close to freezing.
