Thermostat TOA-T101, TOA-T102
Overview
The TOA is an electronic thermostat (temperature monitor) for NTC
temperature sensors with outputs for 230V or 24 V AC/DC 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)
It can be adjusted by the user using the OPA-S operating terminal if
required.
Note: The thermostat does not include temperature sensors. These need
to be ordered separately.
