6. Outdoor temperature dependent switching between supply air temperature
control and extract air temperature control
When the outdoor temperature is lower than a settable limit (winter), outdoor compensated supply
air temperature control will be active, otherwise (summer) cascaded room temperature control as in
control mode 4.
7. Outdoor compensated room temperature control
The room temperature can be compensated when the outdoor temperature increases. One can, for
instance, imagine accepting a slightly higher room temperature if it is warm outside or, conversely,
a slightly lower temperature if it is chilly. This function is included to conserve energy.
8. Outdoor compensated extract air control
The extract air temperature can be compensated when the outdoor temperature increases. One can,
for instance, imagine accepting a slightly higher extract air temperature if it is warm outside or,
conversely, a slightly lower extract air temperature if it is chilly. This function is included to
conserve energy.

Control
When the unit is in running mode the heating valve is controlled by the analogue output ”Y1
Heating” or by two digital outputs “Heating 3-pos. actuator, increase” and “Heating, 3-pos. actuator,
decrease”.
