Temperature
In this menu advanced temperature control parameters can
be modified.
Supply air involves keeping a constant supply air temperature
without consideration to the load in the premises.
Extract air involves keeping a constant temperature in the
extract air duct (premises), by modulating the supply air
temperature.
The reaction speed of capacity control signal can be modified.
A higher Setting will result in a smoother control; a lower Set-
ting will result in a faster reaction speed. but also greater risc
of oscillations.
