8.9 ReCO
2
The ReCO
2
function is used for controlling the TBBR air
recirculation section in sequence with CO
2
control or tem-
perature control, for instance.
If both the CO2 and the temperature functions are
selected, the function with the presently lowest signal
(highest outdoor air set point) will apply.
CO
2
function:
The air recirculation rate increases if the input signal for
CO
2
(0-10 V DC) is low and decreases if the input signal is
high.
CO
2
+ flow function:
The air recirculation rate increases if the input signal for
CO
2
(010 V DC) is low and decreases if the input signal is
high. If the input signal for CO
2
still is too high without air
recirculation, the airflow will be steplessly increased to the
max. preset flow setting.
Temperature function for heating, economy:
Recirculation takes place upstream of the reheater.
Temperature function for heating, comfort:
Recirculation takes place downstream of the reheater.
Temperature function for cooling, economy:
Recirculation takes place upstream of air cooler.
Temperature function for cooling, comfort:
Recirculation takes place downstream of the air cooler.

8.10 IQnomic Plus
IQnomic Plus is a name given to additional modules for
extra control functions.
See the special instructions for the IQnomic Plus, and
wherever applicable the relevant Function Guide.

Outdoor air
Pressure sensor for outdoor air
measurements.
The outdoor airflow is kept constant in response to pressure
sensor readings. See special installation instruction for the TBLZ-
1-23-aa Pressure sensor.
When the recirculation damper opens, the speed of the extract
air fan is reduced and vice versa.
