With the OptiTherm you have the possibility to measure the room temperature by:
1. Thermostat: sensor built-in to OptiTherm itself
2. External zone: an external sensor connected to each air heater.
3. External average: an external sensor connected on one or more air heaters. Where the average
value is automatically calculated based on the number of connected sensors.
As standard, the temperature sensor on the OptiTherm is used.
