10.3| Supply temperature upper limit
This function protects the environment and the people therein from the infeed of air that is too hot.
The function is enabled with TL5 and requires setting the upper limit TL2 beyond which the supply temperature
must not rise.
The behavior mirrors what follows for the lower supply limit. When the supply temperature “SUP - Supply Temp”
rises above the upper limit TL2 decreased by band TL6, the heating device and any damper to feed in outside air
(free-heating) are limited in a manner proportional to amount the supply temperature diers from the limit setpoint.
Above the setpoint, the limitation is total
